P = 2l + 2w
2w = p - 2l
w = (p - 2l)/2
Answer:
see below
Step-by-step explanation:
first isolate x
3x = -135
divide both sides by 3
3x/3 = x
-135/3 = -45
x = -45
we can then graph it
x is gonna be equal to -45
so draw a point on the x intercept at -45 and draw a vertical line going up and down
it should look like the graph shown below
Y=1/2x+1/2
the y intercept is 1/2 and the slope is 1/2
Answer:
5x + 20 + (-20) = 5x
Step-by-step explanation:
Opposite of 20 is just -(20) which is -20.
5x + 20 + (-20) = 5x + 20 -20 = 5x
