Question

Evaluate b*2−16a+5 when a=1/2 and b=7.

Answer 1

To evaluate the expression b*2−16a+5 when a=1/2 and b=7, substitute the values of a and b into the expression and simplify.

Step-by-step explanation:

To evaluate the expression b*2−16a+5 when a=1/2 and b=7, we substitute the values of a and b into the expression:

b*2−16a+5 = 7*2 − 16*(1/2) + 5

Next, we simplify the expression:

7*2 − 16*(1/2) + 5 = 14 - 8 + 5 = 11

Therefore, the value of the expression b*2−16a+5 when a=1/2 and b=7 is 11.
