Answer:
42
Step-by-step explanation:
ABC + CBD = ABD
3x+33 + 5x+13 = 70
Combine like terms
8x +46 = 70
Subtract 46 from each side
8x+46-46 = 70-46
8x = 24
Divide each side by 8
8x/8 = 24/8
x=3
We want to find ABC
ABC = 3x+33 = 3*3 +33 = 9+33 = 42

Answer:
Step-by-step explanation:
7.50a + 2.50c = 1945
a + c = 364
Use -2.50 for 2nd equation
7.50a + 2.50c = 1945
-2.50a - 2.5oc = -910
5a = 1035
a = 207 adult tickets were sold
207 + c = 1945
c = 1738 child's tickets were sold
