Duane's mom bought him a new pair of sneakers for his birthday. She wants to wrap the gift, but is not sure how much wrapping paper to purchase. The shoe box measures 10 inches long, 13 inches wide, and 5 inches tall. The wrapping paper comes in sheets that measure 26 inches by 17 inches. How many sheets of wrapping paper will Duane's mom have to purchase?

1.47 sheets

Step-by-step explanation:

Duane's mum purchased a new pair of sneakers for him on his birthday.

Length of shoe box= 10 inches

Width of shoe box= 13 inches

Height of shoe box= 5 inches

Volume of the shoe box= length×width×height

= 10 × 13 × 5

= 650 inches

The wrapping paper measures 26 inches by 27 inches

= 26 × 17

= 442 inches

The sheets of wrapping paper that Duane's mum need to buy will be:

Volume of shoe box divided by measurements for wrapping paper.

= 650 / 442

= 1.47 sheets

Step-by-step explanation:

A: x = 12-4 = 8

B: x =  12/4 = 3

No wonder you asked for help. Some of the questions don't make sense!

x+3 = 9 ⇒ x=6, which doesn't match either A or B.

3·x = 9 ⇒ x=3, which matches B

9 = 3·x is the same as the previous equation, i.e., B.

3+x = 9, doesn't match either A or B.

x = 9-3, doesn't match either A or B

x = 9÷3 ⇒ x=3, which matches B

x+x+x = 9 ⇒ x=3, which matches B

I'm guessing that there is an error in tape A, and x should be 6, not 8.
