Answer:

- 30(x + 5) = 7x - 7 \\  - 30x - 150 = 7x - 7 \\ 7x + 30x =  - 150 + 7 \\ 37x =  - 143 \\ x =    \frac{ - 143}{37}  \\ x =  - 3.864

________o____o_____

30–(x+5)=7x-7

30 – x–5 =7x -7

7x+x = 30-5+7

8x = 32

x= 32/8

x=4

I hope I helped you^_^

X=4
30-x+5=7x-7
25-x=7x-7
-x+25=7x-7
-x=7x-32
(subtract 7x from both sides)
-8x=-32
(divide by -8) (remember negative times negative= positive)
X=4

In the aftermath of a car accident, it is concluded that one driver slowed to a halt in 20 seconds while skidding 1775 feet. If
-Dominant- [34]
Assume uniformly accelerated motion

Vf = Vo - at => a= [Vo - Vf] / t

Vf = 0, t = 20 s => a = Vo / 20

x = Vot - at^2 / 2

x = Vot - (Vo / 20) * t^2 /2

x = 1775 feet * [1 mile / 5280 feet] = 0.336 mile

t = 20 s

=> 0.336 = 20Vo - Vo(20)^2 /(40) = 20Vo - 10 Vo = 10 Vo

=> Vo = 0.336 /10 = 0.0336 mile /s

Vo = 0.0336 mile/s * 3600 s/h = 120.96 mile / h

Therefore, the car was way over the speed limit.
