Please help? 1) - 12 = r + 5
2) x + 4 =- 8
3) 32 = - 4 f
4) 4 = 7 +z
5) 7 = - 2 +k

r=-17

x=-12

f=-8

z=-3

k=9

Step-by-step explanation:

-12=r+5

Subtract 5 from both sides

-17=r

x+4=-8

Subtract 4 from both sides

x=-12

32=-4f

Divide both sides by -4

-8=f

4=7+z

Subtract 7 from both sides

-3=z

7=-2+k

Add 2 to both sides

9=k

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
