Answer:
r =.3 is wrong for 2x = -6. you divide -6/2 which = -3 so r = -3
Wesley can fill 2 mugs of hot chocolate
X-1= 5x+3x-8
Combine like terms
x-1= 8x-8
Our goal is to isolate x by cancelling out other numbers.
Subtract x from both sides
x-1-x= 8x-x-8
-1= 7x-8
Add 8 to both sides
7=7x
Divide both sides by 7
1=x
Final answer: x=1
72.5+32.7= 105.2
Triangle angles have to equal 180
180-105.2= 74.8
Third angle= 74.8 degrees
