I NEED HELP!!!! WITH NUMBER 9, & 10??
Answer:
awnser one is 7 and question 2 is -10
Step-by-step explanation:
−12−2−−55=? question one
In the first fraction, the negative numerator and negative denominator cancel each other.
Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
122+55=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(12/2, 5/5) = 10
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(122×55)+(55×22)=?
Complete the multiplication and the equation becomes
6010+1010=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
60+1010=7010
Since 70 divided by 10 equals 7 then,
7010=7
Therefore:
−12−2−−55=7
Question 2
−81+6−3=?
In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.
The equivalent equation is
−81+−63=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-8/1, -6/3) = 3
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−81×33)+(−63×11)=?
Complete the multiplication and the equation becomes
−243+−63=?
The two fractions now have like denominators so you can add the numerators.
Then:
−24+−63=−303
Since -30 divided by 3 equals -10 then,
−303=−10
Therefore:
−81+6−3=−10
Solution by Formulas
Apply the fractions formula for addition, to
−81+6−3
and solve
(−8×−3)+(6×1)1×−3
=24+6−3
=30−3
=−10
A triangle has sides with lengths of 6 centimeters, 5 centimeters, and 3 centimeters. Is it a right triangle?
Answer:
No
Step-by-step explanation:
A triangle with a side of five is only a perfect right triangle when it's in a 5,12,13 ratio.
Furthermore, to check, 5^2 is 25 and 3^2 is 9. 25+9 is 34, which doesn't not have a square root of 6.
A store is advertising a sale with 10% off all items in the store. Sales tax is 5%.A 32-inch television is regularly priced at $295.00. What is the total price of the television, including sales tax, if it was purchased on sale? Fill in the blank to complete the sentence. Round your answer to the nearest cent.
Answer:
$280.25Step-by-step explanation:
Step one;
given
price= $295.
Discount
10% of 295
=10/100*295
=0.1*295
=29.5
new price= 295-29.5=
=$265.5
Tax
5% of 295
=5/100*295
=0.05*295
=14.75
tax=$14.75
Total price= discount sales+tax
=265.5+14.75
=$280.25

Angle PQR is a straight angle.
The measure of angle SQR is 25°.
The measure of angle PQS is xº.
What is the value of x?
Answer:
x=155
Step-by-step explanation:
since its a straight line, it has to equal 180 in total.
SQR is 25, so to find PQS you subtract 180-25
Which equals 155

(x^3 + 8x^2 + kx + 4) ÷ (x+ 2)
Please help how do i solve for k please include steps this is called remainder theorem
Answer: 14
Step-by-step explanation:
Check it
Answer:
k = 14
Step-by-step explanation:
The Remainder theorem states that if f(x) is divided by (x + h) then the remainder is f(- h)
If (x + h) is a factor of f(x) then the remainder is zero, that is f(- h) = 0
Given (x + 2) is a factor of f(x) then f(- 2) = 0, that is
(- 2)³ + 8(- 2)² - 2k + 4 = 0
- 8 + 8(4) - 2k + 4 = 0
- 8 + 32 - 2k + 4 = 0
- 2k + 28 = 0 ( subtract 28 from both sides )
- 2k = - 28 ( divide both sides by - 2 )
k = 14

Step-by-step explanation:
You want to start by looking for two coordinates and decide which ones you'll use.
Then you want to find the difference between the two y coordinates also known as the rise.
Then you'll want to find the difference between the two x coordinates also known as the run.
After that you'll want to divide the difference of the two y coordinates with the difference of the x.
Hopefully this helps, much love.

Answer:
A
Step-by-step explanation:
1/6^2 =
1/36
Answer:
B
Step-by-step explanation:
When you divide 2 numbers with the same base, you subtract the exponents. We know fractions are basically division, so we would do 3-5. You get -2 as your exponent and we know negative exponents can be written two ways: [tex]6^{-2} and \frac{1}{x6^{2} }[/tex]. Both of those are there, so they are not the correct answer. B can be determined as the one not because the exponent is positive.

Lisa hikes 9 miles in 2 hours. At this rate, how far does she hike in
1/6
hours?
Answer:
72 miles
Step-by-step explanation:
Answer:
0.75 or 3/4 miles hiked in 1/6 hours
Step-by-step explanation:
2 hours = 120 minutes
1/6 x 60 = 10 minutes
9 / 120 = 0.075 miles per minute
10 x 0.075 = 0.75
At a bake sale, a student spent $5.70 buying 3 brownies and 5 cookies. His
friend spent $4.50 buying 1 brownie and 6 cookies. What is the price of a
brownie?
Answer:
i think the answer would be 90 cents for each brownie
Step-by-step explanation:
This can be solved as a system of 2 linear equations.
x = price of a brownie
y = price of a cookie
Since $5.70 bought 3 brownies and 5 cookies, our first equation is:
3x + 5y = 5.70
Since $4.50 bought 1 brownie and 6 cookies, our second equation is:
x + 6y = 4.50
So just solve the following system for x and y:
3x + 5y = 5.7
x + 6y = 4.5
Get x = 4.5 - 6y from the bottom equation and substitute for x in the top equation:
3(4.5 - 6y) + 5y = 5.7
Solve for y:
13.5 - 18y + 5y = 5.7
-13y = -7.8
y = 7.8/13 = 0.6 = price of cookie = $0.60
Now substitute this value of y into either equation and get x. From the bottom equation,
x + 6(0.60) = 4.50
Solve for x:
x = 0.9 = price of brownie = $0.90
