Answer:
x=-10
Step-by-step explanation:
3x-4(2+3x)=82
3x-(4*2)+(4*3x)=82
3x-8-12x=82
-9x-8=82
-9x-8+8=82+8
-9x=90
-9x/-9=x
90/-9=-10
x=-10

Answer:
Step-by-step explanation:
Given that,
Initial speed of a car, u = 60 mph = 26.82 m/s
Final speed of a car, v = 10 mph = 4.47 m/s
Time, t = 5 s
We need to find the acceleration of the car. The rate of change of velocity is called the acceleration of an object. It can be given by :
So, the acceleration of the car is 
and it is deaccelerating.
Answer:
6%
Step-by-step explanation:
The percentage is the ratio 15/250 converted to a percent. That conversion can be accomplished by multiplying the ratio by 100%. (You can do this without a calculator.)
