Answer:
a = c + 16
Step-by-step explanation:
a = b + 12
b = c + 4
Solve for b in the first equation.
a = b + 12
a - 12 = b
Put b as a - 12 in the second equation and solve for a.
a - 12 = c + 4
a = c + 4 + 12
a = c + 16
9r
Explanation:
4r + 9r = 13r
13r-11r = 2r
2r + 7r = 9r
The answer is 4 and 3/8, because if you subtract 5 3/4 from 10 1/8, you'll get your answer: 4 3/8. Hope this helps, and good luck!!
