Answer:

Step-by-step explanation:

5y + 6y + 7y = 18y......any numbers that add(or subtract) to equal 18, stick them before the y....

Answer:

(B)Finding the product of 9, 10, and 9.
(D)810

Step-by-step explanation:

Given a rectangular prism shaped storage shed with dimensions:

9 feet by 9 feet by 10 feet

Volume of a rectangular prism =Length X Width X Height

Tammy can find the volume of the storage unit by finding the product of 9, 10, and 9.

Therefore:

Volume of the storage shed= 9 X 9 X 10 $=810cm^3$

Therefore, to completely fill the storage shed, Tammy would need 810 unit boxes that each measure 1 cubic foot

qwelly [4]

Answer:

563.53%

Step-by-step explanation:

Suzanne's cell phone monthly bill = $85

The money spent on her cell phone bill is 563.53% of the money spent on student health insurance.

On an annual basis, the first set of expenses (cell phone) is 563.53% of the second set of expenses (health insurance)
