Question

What is the value of this expression when g= -3.5?8-|2g-5|a. 20b. 10c. 6d. -4​

Answer 1

Answer:

d. -4

Step-by-step explanation:

Let's plug in g

8 - |2(-3.5) - 5|

8 - |-7-5|

8 - |-12|

The absolute value is always positive of any number,

8 - 12

= -4

Answer 2

Answer:

D. -4

Step-by-step explanation:

We are given this expression:

$8-|2g-5|$

and asked to evaluate when g= -3.5 Therefore, we must substitute -3.5 in for g.

$8-|2(-3.5)-5|$

First, multiply 2 and -3.5

2 * -3.5 = -7

$8-|-7-5|$

Next, subtract 5 from -7.

-7-5= -12

$8-|-12|$

Next, evaluate the absolute value of -12. The absolute value is how far away a number is from 0, and it is always positive. The absolute value of -12 is 12.

$8-12$

Subtract 12 from 8.

$-4$

The value of the expression is -4 and D is the correct answer.
