Answer:
z = 66
Step-by-step explanation:
RS = z
QT = z - 33
Based on the midsegment theorem, QT = ½(RS)
Plug in the values
z - 33 = ½(z)
Multiply both sides by 2
2(z - 33) = z
2z - 66 = z
Add 66 to both sides
2z = z + 66
Subtract z from both sides
2z - z = 66
z = 66

40 x 0.8 = 32
The first one is no solution, the second one is t+x=y

I really hope this will help u
Multiply -2 with x equaling -2x
Multiply -2 with +6 equaling -12
Y - 5 = -2x - 12
Add 12 on both sides
Y - 5 + 12 = -2x - 12 + 12
Y + 7 = -2x
Divide by -2 on both sides
Y + 7 / -2 = -2x/-2
Y + 7
------- = x
- 2
