Add the 2 coefficients because they are considered like terms.
Your answer should be 25b to the 4th
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
(divided both sides by -3z)
z=

Step-by-step explanation:
c is cat food d is dog food
3c + 4d = 43

2d = 11
d = 5.50
3c + 2d = 3c + 22 = 43
3c = 21
c = 7
c+d = 7 + 5.50 = 12.50

18 inches = 1.5 feet
Multiply 2 on both sides;
36 inches = 3 feet
As for 72 inches, multiply each side by 4
18 inches = 1.5 feet

As for 144 inches, divide both sides by 18
1 inch is approximately 0.083
Multiply both sides by 144
144 inches = 12 feet
