Answer 1

790-280=510

280-120=160

Answer 2

To find the values of the expressions 790 - a and a - 120 when a = 280, simply substitute the value of a into the expressions and perform the calculations:

1. For the expression 790 - a: 790 - a = 790 - 280 = 510

2. For the expression a - 120: a - 120 = 280 - 120 = 160

So, when a = 280, the values of the expressions are: 790 - a = 510 a - 120 = 160
