Question

3. What value of y makes this true? 25 - y<15 A. 8 B. 9 C. 10 D. 11

Answer 1

To figure out which value of y makes this true, plug in each option:

y = 8

25 - y < 15       Plug in 8 for y

25 - 8 < 15

17 < 15      This is false because 17 is not less than 15

y = 9

25 - y < 15     Plug in 9 for y

25 - 9 < 15

16 < 15     This is false because 16 is not less than 15

y = 10

25 - y < 15       Plug in 10 for y

25 - 10 < 15

15 < 15    This is false because 15 can't be less than itself (15)

y = 11

25 - y < 15     Plug in 11 for y

25 - 11 < 15

14 < 15       This is true because 14 is less than 15

Your answer is D
