Answer:
y=11
Step-by-step explanation:
To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.
To Check your answer:
Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.
C + d = 180°(supplementary angle)
C = 5d
5d + d = 180°
6d = 180°
d = 180°/6
d = 30°
Since C = 5d,
C = 5 x 30°
Therefore, C = 150°
