I think it is 13 is the answer
8x−2=−9+7x
Simplify:
8x−2=−9+7x
8x+−2=−9+7x
8x−2=7x−9
Subtract 7x from both sides.
8x−2−7x=7x−9−7x
x−2=−9
Add 2 to both sides.
x−2+2=−9+2
x=−7
I think you just multiply the amount of pennies for one grooming job by 9
Answer:
A
Step-by-step explanation:
Answer:
-20 m/s.
Step-by-step explanation:
The computation of the average speed is shown below:
Given that
The initial velocity of the bus, u = 20 m/s
Aceleration of the bus, -a = 8 m/s²
time of motion, t = 5 s
Now The final velocity of the bus is
v = u + at
v = 20 + (-8 × 5)
v = 20 - 40
v = -20 m/s.
