10. What is the value of x in this equation?
-4x + 8 = 42

x = -17/2

Step-by-step explanation:

-4x + 8 = 42

Subtract 8 from each side

-4x+8-8 = 42-8

-4x = 34

Divide each side by -4

-4x/-4 = 34/-4

x = -17/2

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
