Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
The answer would be 2/5
4. divided by 2 = 2
—-
10. divided by 2 = 5
3x + 8(x + 9) = -5
3x + 8x + 72 = -5
11x + 72 = -5
11x + 72 - 72 = -5 - 72
11x = -77
11x/11 = -77/11
x = -7
All you have to do for this equation is to substitute the y in the second equation with what y equals to. Then you distribute and combine like-terms.
