Answer:
Equation for x: 3x - 6 = 
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = 
3x - 6 = 
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21
Answer:
x=10, y=5
Step-by-step explanation:
For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.
x-2y=0
x=2y
You can substitute 2y as x on the first equation (x+4y=30).
2y+4y=30
6y=30
y=5
Plug y=5 into any equation.
x+4(5)=30
x+20=30
x=10
Because if you a model your not going to get the right answer
The answer would be the first one
