Question

Evaluate the expression by using the given values of the variables. y ÷ 4 • 3 – 6 ÷ x + 8 where x = 3 and y = 24

A.
8

B.
12

C.
–8

D.
24

Answer 1

y ÷ 4 • 3 – 6 ÷ x + 8 replace y with 24 and x with 3

24 ÷ 4 • 3 – 6 ÷ 3 + 8

6 • 3 – 6 ÷ 3 + 8

18 – 6 ÷ 3 + 8

18 - 2 + 8

16 + 8

24

Answer 2

First you plug in the the variable values.

24/4 × 3 - 6/3 + 8.

Then you follow the procedure using order of operations (First you do multiplication/division right to left, then subtraction/addition)

24/4 is 6, then multiply by 3 which is 18.

So far you have 18 - 6/3 + 8. Then you divide 6/3 because it is division and you get 2.

18 - 2 + 8, then you subtract 2 from 18 to get 16 and add 8 which is 24. So the answer is D
