Question

14=m-(-3)
-9r+12=-24
2.8=-3t-9.2
7(w+4)=49
1/2 (-8k+)=18

Answer 1

Explanation:

14=m-(-3)

14=m+3

m = 11

-9r+12=-24

-9r = -36

r = 4

2.8=-3t-9.2

3t= -9.2 -2.8

3t = - 12

3 = -4

7(w+4)=49

7w + 28 = 49

7w = 21

w = 3

1/2 (-8k+)=18 [Was there supposed to be a number after the "-"?]

-4k = 18

k = - 4.5
