Answer:
12
Step-by-step explanation:
They are the same angle so they must be equal.
So, x+5 = 2x-7
5+7 = 2x-x
12 = x
<em>I </em><em>think </em><em>41 </em><em>is </em><em>correct </em><em>answer</em>
Step-by-step explanation:
(7+8)-(5+9)+4(2+5)
=15-14+4(10)
=1+40
=41
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.
