(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:
3/1 is the <u>ans</u>
Step-by-step explanation:
here y is in 3
and x is in 1
so proportonality will be 3/1
the answer is more than 1 i believe :) yw hope this helped
Answer:
Subtract 4 on both sides, then divide by 2 to find y
Step-by-step explanation:
width: x/2, Length:x
18=x(x/2), 18=x^2/2, 36 = x^2, x= -6,6 Use the positive value of 6 for x. the width will be 6/2=3.
