Answers
6x + 27
Step-by-step explanation:
Multiply 3 by the numbers in parentheses
3(2x + 9) = 6x
Step 1: Simplify both sides of the equation.
3(2x+9)=6x
(3)(2x)+(3)(9)=6x (Distribute)
6x+27=6x
Step 2: Subtract 6x from both sides.
6x+27-6x=6x-6x
27=0
Step 3: Subtract 27 from both sides
27-27=0-27
0=-27

Answer:
-10
Step-by-step explanation:
The reason why I believe the answer to your question is -10 is because inequality represents the difference in size, degree, circumstances, etc.; lack of equality. So I had to find the difference between -5 and 5, and -5 minus 5 is -10.

Two radio stations are playing this week's #1 hit song. One radio station plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3pm. How many minutes will pass before they play the same song again.
Answers
Answer:
72 minutes until they play again
Step-by-step explanation:
18+18+18+18=72
24+24+24=72
Answer: 72 minutes
======================================================
Explanation:
The GCF of 18 and 24 is 6, since this is the largest factor shared between the two numbers
18 = 6*324 = 6*4To find the LCM, we'll involve the GCF. The LCM of two numbers x and y is found by multiplying them, and then dividing over the GCF of them.
LCM of x and y = (x*y)/(GCF of x and y)
LCM of 18 and 24 = (18*24)/6
LCM of 18 and 24 = 432/6
LCM of 18 and 24 = 72
-----------
To help confirm this, we can list out the multiples of each
multiples of 18 are: 18, 36, 54, 72, 90, ...multiples of 24 are: 24, 48, 72, 96, ...We see that 72 is the lowest common multiple. This is the final answer because each station will play the same song 72 minutes apart.
The stations play the same song at 3 PM. Then 72 minutes later (4:12 PM), the same song is played again on both stations at the same time. Then at 5:24 PM, another 72 minute gap, is when the same song is played again at the same time. And so on.
----------
Side note: 72 minutes = 60 min + 12 min = 1 hr, 12 min

First you split the shape into a rectangle and a triangle. So now you have a triangle with the sides 4 x 3.6 and a triangle with the sides 4 x 2.7.
Side note: 2.7 comes from subtracting 3.6 off of 6.3.
Rectangle:
A = lw
A = 4 (3.6)
A = 14.4m²
Triangle:
A = 1/2lw
A = 1/2 (4) (2.7)
A = 5.4m²
Then you add the areas of both the rectangle and the triangle together.
14.4 + 5.4 = 19.8m²

Answers
Answer for number 4:
4. It will take them 3.5 hours on the fourth day.
Alright, so this is a multistep problem.
1. We need to calculate how many miles they have already traveled.
In order to do that, we multiply the number of hours by the average speed on each day.
- On day 1, they drove 5 hours at an average of 70 mph. 5 * 70 = 350, so they drove 350 miles on the first day.
- On day 2, they drove 7 hours at an average of 65 mph. 7 * 65 = 455, so they drove 455 miles on the second day.
- 350 miles + 455 miles = 805 miles, so they've driven 805 miles so far.
2. We need to figure out how far they have left to travel.
They started out with 1,050 miles, so they've got 245 miles left. 1,050 - 805 = 245.
3. We need to figure out how many hours they've got left to drive.
On the third day, they drive at an average speed of 70 mph, and they've got 245 miles left. to find the amount of time they need to drive, we divide the distance by the speed.
245 miles ÷ 70 mph = 3.5 hours. Therefore, it will take them 3.5 hours to reach their friend's home.
Answer For Number 5:
10 gallons of water will leak out in 30 hours.
This question involves unit rates.
1. We need to figure out how much water leaks out per hour.
- Since 7 gallons of water will leak out in 21 hours, we divide the amount of water by the amount of time it took for it to leak out. The answer will be how much water leaks out in an hour.
- 7 gallons ÷ 21 hours = 1/3 gallon of water. Now we have our unit rate. Every hour, 1/3 gallon of water leaks out.
2. We need to figure out how much water will leak out in 30 hours.
- Since we know how much water leaks out in 1 hour, we can easily figure out how much water leaks out in 30 hours. All we need to do is multiply how much water leaks out in one hour by 30!
- 1/3 gallon * 30 hours = 10 gallons of water.
Therefore, 10 gallons of water will leak out in 30 hours.
I hope this helps!
But I’m pretty positive about number 5 it was easy so: 1st step is we need to find how much the faucet fills the bucket per hour then multiply it by three in that way we know how many gallons of water will there be in 30 hours :
21 divided by 7 = 3 gallons of water per hour
So 3 x 30 = 90 gallons of water in 30 hours
So that’s the whole thing I hope you got the whole idea and my explaining was good enough ☺️

Answers
Answer:
Step-by-step explanation:
The natural numbers, whole numbers, and integers are all subsets of rational numbers. In other words, an irrational number is a number that can not be written as one integer over another.
Moderators i have not copied this ans
..? ⬇️
The natural (or counting) numbers are 1,2,3,4,5,
1
,
2
,
3
,
4
,
5
,
etc. There are infinitely many natural numbers. The set of natural numbers, {1,2,3,4,5,...}
{
1
,
2
,
3
,
4
,
5
,
...
}
, is sometimes written N
N
for short.
The whole numbers are the natural numbers together with 0
0
.
(Note: a few textbooks disagree and say the natural numbers include 0
0
.)
The sum of any two natural numbers is also a natural number (for example, 4+2000=2004
4
+
2000
=
2004
), and the product of any two natural numbers is a natural number (4×2000=8000
4
×
2000
=
8000
). This is not true for subtraction and division, though.
The rational numbers are those numbers which can be expressed as a ratio between two integers. For example, the fractions 13
1
3
and −11118
−
1111
8
are both rational numbers. All the integers are included in the rational numbers, since any integer z
z
can be written as the ratio z1
z
1
.
All decimals which terminate are rational numbers (since 8.27
8.27
can be written as 827100
827
100
.) Decimals which have a repeating pattern after some point are also rationals: for example,
0.0833333....=112
0.0833333....
=
1
12
.
The set of rational numbers is closed under all four basic operations, that is, given any two rational numbers, their sum, difference, product, and quotient is also a rational number (as long as we don't divide by 0
0
).
An irrational number is a number that cannot be written as a ratio (or fraction). In decimal form, it never ends or repeats. The ancient Greeks discovered that not all numbers are rational; there are equations that cannot be solved using ratios of integers.
The first such equation to be studied was 2=x2

1.414
2
=
1.999396
, which is close to 2
2
. But you'll never hit exactly by squaring a fraction (or terminating decimal). The square root of 2
2
is an irrational number, meaning its decimal equivalent goes on forever, with no repeating pattern:
2‾√=1.41421356237309...

1.41421356237309...

and e

, the most important number in calculus:
e=2.71828182845904...
e

2
and the golden ratio), and transcendental numbers, which are not the solutions of any polynomial equation. π
π
and e
e
are both transcendental.
The real numbers is the set of numbers containing all of the rational numbers and all of the irrational numbers. The real numbers are “all the numbers” on the number line. There are infinitely many real numbers just as there are infinitely many numbers in each of the other sets of numbers. But, it can be proved that the infinity of the real numbers is a bigger infinity.
The "smaller", or countable infinity of the integers and rationals is sometimes called ℵ0
ℵ
0
(alef-naught), and the uncountable infinity of the reals is called ℵ1
ℵ
1
(alef-one).
There are even "bigger" infinities, but you should take a set theory class for that!

Angie and Kenny play online video games. Angie buys 1 software package and 2 months of game play. Kenny buys 1 software packages and 6 months of gameplay. Each software package costs $50. If their total is $250, what is the cost of one month of gameplay?
Answers
Answer:
$18.75 is the cost for 1 month of gameplay.
Step-by-step explanation:
2 software packages in total
Unit price for software package is $50, and since there are two packages, $50x2=$100
Now, we know that the total amount of money that the software cost was $100, we can do 250-100=150
150 is how much they spent for 8 months of gameplay. (2+6=8)
To find how much 1 month of gameplay costs, we need to do 150/8 which is equivalent to $18.75
18.75 is the cost of One month of gameplay

**Solve the equation:
x(x+3)(x+3)=0
Answers
Answer:
three solutions: {-3, -3, 0}
Step-by-step explanation:
This polynomial has already been factored, and the factors are x, x + 3 and x = +3. To solve this equation, set each of the factors equal to zero separately and solve each of the resulting equations:
x = 0 is a solution; the given equation equals zero when x = 0.
The next factor is x + 3; setting this equal to 0 yields the solution x = -3.
The last factor is x + 3; x = -3 is the third solution.
In summary, (x + 3)(x = 3) = 0 has two solutions; we call them "repeated roots." x(x + 3)(x = 3) = 0 has three solutions: {-3, -3, 0} of which two are "repeated."
