Answer: I think so since it’s a decimal
Step-by-step explanation:
Answer:
A = 120
C = 45
Step-by-step explanation:
(12x + 12) + 15 + (3x + 18) = 180
(12x + 3x) + (12 + 15 + 18) = 180
15x + 45 = 180
15x = 180 - 45
15x = 135
x = 135/15
x = 9
A = 12x + 12 = 12(9) + 12 = 108 + 12 = 120
C = 3x + 18 = 3(9) + 18 = 27 + 18 = 45
