2(3t - 1) - 5(t - 1)
2(3t) - 2(1) - 5(t) + 5(1)
6t - 2 - 5t + 5
6t - 5t - 2 + 5
t + 3
I hope this helps you
2x+7=3x-7
x=14
2x+7+12y+1=180
2.14+8+12y=180
12y=180-36
12y=144
y=12
The measure of exterior all angles of a regular n-agon is 180
now for the decagon which has 10 angles is 180/10=18
Slope=5. The change in y is +5and the change in x values is +1. 5/1=5
