Answer:

x = -6

Step-by-step explanation:

-5(x + 3) = 15

Distribute the -5

-5x -15 =15

Add 15 to each side

-5x-15+15 =15+15

-5x = 30

Divide each side by -5

-5x/-5 = 30/-5

x =-6

r-ruslan [8.4K]

Answer:

10 hours

Step-by-step explanation:

speed = distance/time

s = d/t

d = st

d = 75 km/h * 8 h = 600 km

t = d/s

t = 600 km/(60 km/h) = 10 h

Answer: 10 hours

Step by step If C(m)=0.50m + 30 represents the cost of renting a car, how many miles were driven if the cost is $130

Likurg_2 [28]

Answer:

200 miles were driven

Step-by-step explanation:

We know that $C (m) = 0.50m + 30$ represents the cost of renting a car

Where m represents the number of miles driven

If we know that the cost was $ 130 then we can equal C(m) to 130 and solve for m.

$C(m) =0.50m + 30=130$

$0.50m + 30=130$

$0.50m=130-30$

$0.50m=100$

$m=\frac{100}{0.50}$

$m=200\ miles$

Solve the inequality <br>4x - 4> x - 16

Liono4ka [1.6K]

The solution of the given inequality is:

x>-4

Step-by-step explanation:

Given inequality is:

$4x-4>x-16$

Subtracting x from both sides

$4x-4-x>x-x-16\\3x-4>16$

Adding 4 on both sides

$3x-4+4>-16+4\\3x>-12$

Dividing\ both\ sides\ by\ 3

$\frac{3x}{3}>\frac{-12}{3}\\x>-4$

The solution of the given inequality is:

x>-4
