Question

In 21-23, evaluate each expression for the given valué.

21. j + (-6); j-3
22. 8-g+2; g=-10
23. 3m +5; m = -15.

Answer 1

21. Since you didn't say what the value of j was. If j equal -3 then

21. −3 + (−6)

Subtract 6 from −3 to get −9.

−9

OR IF IT EQUALS 3

21. 3 + −6

Subtract 6 from 3 to get −3.

−3

22. 8 − −10 + 2

The opposite of −10 is 10.

8+10+2

Add 8 and 10 to get 18.

18+2

Add 18 and 2 to get 20.

20

23. 3 x −15 + 5

Multiply 3 and −15 to get −45.

−45+5

Add −45 and 5 to get −40.

−40
