The standard form: Ax + By = C
y = 90 - 15x <em>add 15x to both sides</em>
<h3>15x + y = 90</h3>
A and C are rational numbers
Answer:
its 42
Step-by-step explanation:
315-18+81=378
Correct mean =378/9=42
Alternate interior angles are:
(2x-70) = (x+30)
2x-x = 30+70
x = 100
the angle 5y is supplementary to the other angle.
5y + (100+30) = 180
5y + 130 = 180
5y = 180-130
5y = 50
y = 50/5
y = 10
