−(2x+5)=−10−2x
Step 1: Simplify both sides of the equation.
−(2x+5)=−10−2x
−2x+−5=−10+−2x(Distribute)
−2x−5=−2x−10
Step 2: Add 2x to both sides.
−2x−5+2x=−2x−10+2x
−5=−10
Step 3: Add 5 to both sides.
−5+5=−10+5
0=−5
Answer:
There are no solutions.
Answer:
15.5 seconds.
Step-by-step explanation:
From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.
During this time the car slowed down from 8 m/s to 0 m/s.
Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant acceleration:
s = (u + v)t / 2 where u = initial velocity, v = final velocity, s = distance and t = the time, so:-
62 = (8 + 0)t/ 2
62 = 8t/2
4t = 62
t = 15.5 seconds.
