Answer:
Step-by-step explanation:
Let the number be x
Four time that number = 4x
The difference between a hundred and a number = 100 -x
100- x = 4x
100 = x + 4x
100 = 5x
5x = 100
x = 100/5 = 20

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
