Answer:
y = 55
Step-by-step explanation:
The sum of the angles of a triangle are 180
40 + y+30 + y = 180
Combine like terms
70 +2y = 180
Subtract 70 from each side
2y = 180-70
2y = 110
Divide each side by 2
2y/2 = 110/2
y = 55
Answer:
-12x + 24
Step-by-step explanation:
Answer:
8. 14x+6+16x+4=130
30x+10=130
30x+10-10=130-10
30x=120
x=4
10. 11x+3-85=5x-10
11x+3-85-5x=5x-10-5x
6x+3-85=-10
6x+3-3-85+85=-10-3+85
6x=72
x=12
