m + p ÷ 5 when m = 1, and p = 5 when x = 2, and y = −7

2

Step-by-step explanation:

WHen you fill in what you know you get

1+5/5

when we divide we get

1+1

Then we add/ subtract what there is to add/subtract

2

Our answer is 2

Y = x+12
52 = x + y

You plug in the (x+12) for y in (52 = x + y) making the equation 52 = x + x +12 or simplified 52 = 2x + 12. You subtract 12 from both sides of the equation to get 40 = 2x. You divide both sides by 2 to get 20 = x.

You then plug in 20 for x in y = x+12, now y = 20 +12. Simplified y = 32

32 + 20 = 52
