Question

Evaluate 9(b+2) -5b for b=1/4

Answer 1

Answer:

19

Step-by-step explanation:

To solve this, we plug in the value 1/4 as b. We will get 9(1/4 + 2) - 5(1/4). 2 is 8/4, so 2 + 1/4 is 9/4, and 9 * 9/4 is 81/4. 5 times 1/4 is simply 5/4, and the answer is 81/4 - 5/4 = 76/4 = 19.

Answer 2

When b=1/4, put b into the equation:

9(b+2) -5b
= 9 [(1/4)+2] -5(1/4)
= 9(2 1/4) - 5/4
= 9 (9/4) - 5/4
= 81/4 -5/4
= 76/4
= 19

Therefore, the answer is 19.
