Answer:
EF = 10
Step-by-step explanation:
DE + EF = DF
5x + x + 8 = 20
6x = 20 - 8
6x = 12
x = 12/6
x = 2
EF = x + 8 = 2 + 8 = 10

Answer:
y= -3/4+5
Step-by-step explanation:
The equation of line in slope intercept form is, y=mx+b, where m is the slope, and b is the y-intercept. The question gave both the slope and the y-intercept, so, you plug in each of the values into the original equation.
Answer:
4.5
Step-by-step explanation:
0.5p-3.45=-1.2
add 3.45 to -1.2 which would leave the equation to look like
0.5p=2.25
then divide 0.5 to both sides cancelling 0.5 leaving the answer to be
p=4.5
