Sarah earns $7.50 per hour babysitting and $5.00 per hour walking dogs. Last week she worked h hours babysitting and twice as many hours walking dogs. Write an expression to show the amount of money Sarah earned last week. Then multiply and combine like terms to write the expression as one term.

$17.5h

Step-by-step explanation:

babysitting = 7.50(h)

dog walking = 5(2h)

total $ earned = 7.5(h)+5(2h)

$17.5h

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
