hammer [34]

Answer:

x = 14 and y = 6

Step-by-step explanation:

To find the solution to this problem, we plug in the values of x and y from each answer choice and simplify.

1.

  • (11) + (9) = 20. 20 = 20.
  • (11) - (9) = 20. 2 ≠ 8.

2.

  • (9) + (11) = 20. 20 = 20
  • (9) - (11) = 20. -2 ≠ 8.

3.

  • (14) + (6) = 20. 20 = 20.
  • (14) - (6) = 8. 8 = 8.

4.

  • (6) + (14) = 20. 20 = 20
  • (6) - (14) = 8. -8 ≠ 8.

Therefore, the correct answer is x = 14 and y = 6.

AnnyKZ [126]
We know that the puppy weights 56 ounces and it tells us that 1 pound = 16 ounces so every 16 ounces we have a pound. It wants to know how many pounds does the puppy weights. 56 / 16 = number of pounds. So 56 divided by 16 = pounds. The puppy weights 3.5 pounds

grandymaker [24]
To answer this question you would start with 1 whole piece and break it into 4 equal pieces. Each piece would be 1/4 of the original.

If you used 3 of these, you are left with 1/4.

Out of the 1/4 leftover, you create 5 equal-sized pieces.

1/4 divided by 5.
1/4 x 1/5 = 1/20 of the original board for each.

A class of 32 students earned
Yuliya22 [10]

Answer:

5/16 Got a C

Step-by-step explanation:

A = 1/4 x 32

B = (32 - A)/2

D = 2

A = 8

B = (32 - 8)/2

B = 24/2

B = 12

D = 2

8 + 12 + 2 = 22

22/32 did not get a C

32/32 - 22/32 = 10/32

10/32 - > 5/16
