Jorie leaves work 30 minutes late. She decides to make up time by taking the toll road instead of side streets. She can travel f

alexandr1967 [171]

Answer:

OPTION C

Step-by-step explanation:

We know that the toll road is 4 times faster than the side streets.

If 'x' represents the number of minutes she usually spend taking the side streets. The $\frac{1}{4} x$ represents the time she takes taking the toll road.

Also we need to create an equation to represent her total travel time, including wait time. Therefore, the equation is:

$y = \frac{1}{4}x + 30$

Therefore, the correct solution is the OPTION C.

E bisects DF , DE = 5y, and EF = 13y-8. Find DE, EF, and DF

bulgar [2K]

It bisects so DE=EF

DE=5y
EF=13y-8

so
5y=13y-8
minus 13y both sides
-8y=-8
divide both sides by -8
y=1

DE=5y=5(1)=5

DE=EF=5

DF=DE+EF=5+5=10

DE=5
EF=5
DF=10
