2(3x-5) + 2(-2x+10)
6x-10 + -4x+ 20
=2x+ 10
The unit rate is a ratio of change in y and into the change on x. It can also be the rise to run or the slope.
18x-16y=5
Subtract 18x from each side
-16y=-18x+5
Divide by -16
y=18/16x-5/16
y=9/8x-5/16 this one is with improper fractions
A) x - 7 > 3 |add 7 to both sides
x > 10
b) x - 7 > 3 |add 7 to both sides
x > 10
