7y+11+7y+11+7y+11=180(A.S.P)
21y+33=180
21y=180-33
21y=147
y=147/21
y=7
y=7
It is 153 meters
9*7 = 63
18*12= 216
216 - 63= 153
Answer:
The correct option is C.
Step-by-step explanation:
The bike shop owner rents out bikes and scooters.
The cost to rent a bike is $15 plus $8 per hour for each hour the bike is rented.
Rent of bike = Fixed rent + Variable rent
The rent function of a bike is

Where, t is number of hours.
The cost to rent a scooter is $35 plus $5 per hour for each hour the scooter is rented.
The rent function of a scooter is

Where, t is number of hours.
The slope intercept form of a line is

Where, m is slope and b is y-intercept.
So by slope intercept form the rate of change of bike is $8 and rate of change of scooter is 5.
8>5
Therefor option C is correct.
She was not supposed to "undistribute" and separate 3x+1 she was supposed to subtract 1 from both sides
