Answer:
-4.5
Step-by-step explanation:
15(2-x)=13(3-x)
Expand parentheses:
30-15x=39-13x
Add 15x to both sides:
30=2x+39
Subtract 39 from both sides:
2x=-9
Divide both sides by 2:
x=-4.5
Hope this helps!
The correct answer is C (x = 20).
Explanation:
(x + 5) + x + (7x - 5) = 180 (Sum of angles in a triangle)
x + 5 + x + 7x - 5 = 180
9x = 180
x = 20
