10a. This equation does not because 3/4 x 8 = 6 and not 9.
10b. This equation doesn’t because 3x8 does not equal 28.
10c. This equation does because 5 x 8 = 40 which means y = 8.
10d. This equation does because 8/2 = 4. Fractions are just division problems and 8 divided by 2 equals 4, meaning y = 8 was n this equation.

Complete Question
On Tuesday Jack bought four boxes. On Wednesday half of all the boxes that he had were destroyed.
Write an expression for how many boxes Jack has now
A. 1/2b+4

C. 4b−1/2b
D. b+42/2
Answer:
C. 4b−1/2b
Step-by-step explanation:

The expression for how many boxes Jack has now is given as
Number of boxes Jack bought in Tuesday - half of the boxes destroyers on Wednesday.
This is expressed mathematically as:
4b - 1/2b
