X=25 degrees
2x+3x+x+30 = 180
6x+30 = 180
180 - 30 = 150
6x = 150
150/6 = 25
X = 25
Perform the indicated multiplication first: -15 + 5q + 4 = 5q - 11
Note that 5q appears on both sides of this equation. Cancelling, we get :
-11 = -11. This is always true. Thus, -5(3-q) +4=5q-11 is true for all q.
I hope this helps you
-20-(4x-1)=-15
-20-4x+1=-15
-20+1+15=4x
-4=4x
x=-1
It would be 0.81 because she got 81/100 right. Hope this helpz..
