(8y + 2) + (25y - 20) = 180 {interior angles on the parallel lines add up to 180)
Remove brackets:
8y + 2 + 25y - 20 = 180
Combine like terms:
33y - 18 = 180
Add 18 to both sides:
33y = 198
Divide both sides by 33:
y = 6
Answer: y = 6
(10x) + (8y + 2) = 180 {Adjacent angles on a straight line add up to 180)
Plug y = 6 into the equation:
(10x) + (8(6) + 2) = 180
Evaluate the bracket:
10x + 50 = 180
Subtract 50 from both sides:
10x = 130
Divide both sides by 10:
x = 13
Answer: x = 13
Answer:
31
Step-by-step explanation:
3 times 2 is 6, plus 1 is 7
7 times 2 is 14, plus 1 is 15
15 times 2 is 30, plus 1 is 31
31 times 2 is 62, plus 1 is 63
63 times 2 is 126, plus one is 127

Answer: h = 7
Step-by-step explanation:
-h/-1 = -7/-1
so h = 7
Answer:
the answer is d
Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
set y to 0
-2x + 1/2y = 18
-2x +1/2(0)=18
-2x / -2 = 18 /-2
x = -9
