Step-by-step explanation:
Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8
True

I'm not sure, but I believe your answer would be
8/10 = 4/20
Forgive me if I'm wrong, but the others seem to say the same thing that this answer doesn't.
