What is the solution to this equation? х/-5= 15
A. X = 3
B. X= -3
C. X= 75
D. x= -75

Step-by-step explanation:

x = 75

Explanation: In this problem, notice that x is being divided by -5 so to get x by itself, we need to multiply both sides of the equation by -5.

Notice that on the left side, the -5 and -5 cancel

each other out so we're just left with x.

On the right side, we have (-15)(-5) which is 75.

So x = 75.

Finally, remember that we can check our answer by

plugging a 75 back into the original equation.

This is shown in red below.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
