Question

If 3a- 7>14, then which of these could a be ? a. 8 b. 5 c. 1 d. -8

Answer 1

Explanation:

3a = 7+14

3a = 21

a = 7

inequality = (7,∞)

if 7, 3a - 7 > 14 = 14 > 14 which is not possible

so its 8

Answer 2

A) 8

Explanation:

Plug in the optional values for "a".

3(8) - 7 = 17

17>14

Repeat with the other options and you'll see this is the only choice.
