First simplify the expression.
1/3(1,650+0.15c)
550+0.05c
Answer is A
Hope this helps!
9x + 26 + 7x - 17 = 2x + (-3x) + 5x =
16x + 9 = 2x - 3x + 5x =
16x + 9 = 4x
9 = 4x - 16x
9 = - 12x
-9/12 = x
- 3/4 = x
X = 15
y = 21
First, solve for x on the right side triangle by adding angles and equaling to 180.
Now since you know the x value, solve the middle angle for the left side triangle. Add all angle on left triangle and equal them to 180.
