Question

Evaluate each expression if x=8, y=14, and 2=-0.67. 2x +15-9

Answer 1

The expression we have to evaluate is:

`2x+15-9​`

and we need to substitute the value of x = 8:

`2(8)+15-9`

Next, we solve the multiplication between 2 and 8, which is equal to 16:

`16+15-9`

And finally we add and substract the corresponding terms:

`16+15-9=22`

Answer: 22
