Solve 3kx + 24 = 9 kx for x.
Answer:
Step-by-step explanation:
3kx + 24 = 9kx
First subtract 3kx to both sides.
24 = 9kx - 3kx
24 = 6kx
Divide both sides by 6
24/6 = kx
4 = kx
Divide both sides by k.
4/k = x
William must have at least $250 this month. He has already earned $100, how much more
should he earn this month? Use m to represent the amount of money he still needs to eam.
Subtract the amount he has from the amount he needs:
M = 250 -100
M = 150
He needs to earn$150 more
Answer:250-100=150

1: Ten baseballs weigh 1,417.4 grams. About how much does 1 baseball weigh? 2: Round your answer to the nearest tenth of a gram. 3:Round your answer to the nearest gram. 4: Which answer would you give if someone asked, "About how much does a baseball weigh?" Explain your choice.
Answer:
141.74 grams
Step-by-step explanation:
According to the given situation, the computation of each baseball weighs is shown below:-
Each baseball weighs = Total weight of all ten baseballs ÷ Total amount
= 1,417.4 ÷ 10
= 141.74 grams
Therefore for determining the each baseball weighs we simply applied the above formula.
The same is to be considered

Write the equation of the line that passes through the points (4, -3) and (3, 2). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
Use the slope equation to find the slope of the 2 points. Then substitute the values given and the slope into the point slope equation.
Step-by-step explanation:
Point slope equation: y − y1 = m(x − x1)
Slope: y2-y1/x2-x1

How do I find x and what’s the relation ?
Answer:
X=17
Step-by-step explanation:
Im sorry if this sounds a bit confusing. Im better at doing the math then explaining it. All the angles in that are 90-degree angles and because of that, you can assume that the angle that you trying to find is also 90 degrees. So to find that equation you can do this.
4x+22=90 -22 from both sides.
-22=-22
you are left with
4x=68 then divide 4 from both sides.
/4=/4
you then get x=17 which is your answer.
Check your answer by plugging 17 into x.
4*17+22=90
The answer is 90 so you are correct.

You are going on a field trip and need to choose where to go, The zoo charges a $100 fee plus $10 per student. The museum charges $200 plus $5 per student. How many students have to go on the trip to make the museum a better deal
Answer:
21 kids have to go on the trip to make the museum a better deal
Step-by-step explanation:
Zoo: y=10x+100
Museum: y=5x+200
10x+100=5x+200
5x=100
x=20
When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars

Answer: A! x=-1 2/5, y= 1 3/5
Step-by-step explanation:
First put -3x+3y=9 into slope-intercept form(y=mx+b)
3y=-3x+9
then solve for y
y=-1x+3
enter your y-intercept into the equation below..
2x-7(-1x+3)=-14
2x+7x-21=-14
2x+7x=-14+21(when changing sides it changes signs that's why 21 is now a positive)
2x-7x=7
-5x=7 divide -5 into 7
7/5
x=-1 and 2/5
then input x back into the first equation
-3(7/-5)+3y=9
21/5+3y=9
3y=9-21/5
3y=24/5
divide 3 into 24/5
=24/15=1 and 9/15 reduce it anddd
y=1 and 3/5
Jill says that 23/1000 can be written as 0.23. Which explains whether or not Jill is correct? A. Yes, Jill is correct. The fraction 23/1,000 is equivalent to 0.23. B. No, Jill is not correct. The fraction is equivalent to 0.023. The decimal 0.23 is equivalent to. C. No. Jill is not correct. The fraction is equivalent to 0.0023. The decimal is 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100.
Answer:
B. No, Jill is not correct, the fraction is equivalent to 0.023.
Step-by-step explanation:
The given fraction is [tex]\frac{23}{1000}[/tex]
Observe that in the denominator there is 1000, which has three zeros after 1.
In changing the given fraction to decimal, there must be 3 significant digits after the decimal.
According to this option (b) is correct.
Moreover, when 23 is divided by 1000, we have
[tex]\frac{23}{1000}=0.023[/tex]
But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.
Hence option (b) is correct,
Write 0.18 as a fraction in simplest form.
Answer: The answer is 9/50

Lucy runs at an average speed of 3.5 miles per hour. John runs 2 miles per hour faster than Lucy. How far will John run (r) he runs x number of hours?
Answer:
It is 5.5 miles/hour if you are trying to figure out how fast john runs.
Step-by-step explanation:
if john run 2 mile/hour faster than lucy, you just have to add how fast lucy is running by 2. This will equal john's miles/hour. now you times 5.5 by how many hours he runs.

Admission to a local aquarium is $10 for
adults and $7 for children. The aquarium
collected $6,549 from the sale of 783
tickets. Find the number of adult tickets and
children tickets that were sold.
First, let's define variables:
A = adults
C = children
Okay, now that's done, time to set up the two equations required to solve:
10a + 7c = 6549
a + c = 783
One way you can solve this is to set up the second equation to isolate a variable. For example,
a = -c + 783
Using this, we can plug it into the first equation and solve for c.
10(-c+783) + 7c = 6549
-3c = -1281
c = 427
Now, use the value of 427and plug it in either equation to solve for a.
a + 427 = 783
a = 356
356 adult tickets were sold, and 427 children tickets were sold.

Which of the following equations are true about the following parallelogram?
Answer:
A, B, E
Step-by-step explanation:
A is true since the sum of the measures of two consecutive angles of a parallelogram is 180 deg.
B is true since opposite angles of a parallelogram are congruent.
C is false since that equation gives x = -1, but x cannot equal -1 since that would make angle 3x - 12 have a negative measure.
D is false for the same reason as choice C.
E is true since x = 20 is the solution of the equations in choices A and B.
