You first multiply the outside exponents into the numbers in the parentheses.
When you have an exponent being multiplied directly to another exponent, you multiply the exponents together.
For example(because I am a bad explainer):
When you divide an exponent by an exponent, you subtract the exponents
For example:
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:
You can think of it like this if you want:
Now multiply the outside exponents into the exponents in the parentheses
Divide 27 and 9
Your answer is 
The text tells us 215 is 86% of the questions
We are looking for 100% of the questions
We get that number by:
Multiplying 100 and 215 and dividing it by 86
And that equals 250
Answer:
$4
Step-by-step explanation:
27 - 3 = 24
24 ÷ 6 = 4

-6.9x - 7.8y = 71.76
to find the y int, sub in 0 for x and solve for y
-6.9(0) - 7.8y = 71.76
-7.8y = 71.76
y = 71.76/-7.8
y = -9.2...so the y int is (0,-9.2)
to find the x int, sub in 0 for y and solve for x
-6.9x - 7.8y = 71.76
-6.9x - 7.8(0) = 71.76
-6.9x = 71.76
x = 71.76 / -6.9
x = -10.4....so ur x int is (10.4,0)
