Answer:
x = 11
Step-by-step explanation:
(3x + 28) + (5x + 52) + ( 2x - 10) = 180
(3x + 5x + 2x) + (28 + 52 - 10) = 180
10x + 70 = 180
10x = 180 - 70
10x = 110
x= 11
(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)
10x+80-10= 180
10x+70=180
10x=180-70
10x=110
x=110÷10
x=11
3xz5+2x+4y−2z
2x−5y+3z5x+9y−2z
=2x+−5y+3xz5+9y+−2z
Combine Like Terms:
=(3xz5)+(2x)+(−5y+9y)+(−2z)
=3xz5+2x+4y+−2z
I think the answer is 43
