Answer:
Step-by-step explanation:
add up their speed.
combined speed = x+ 1 x + 10
( 2 x + 10 )
Time = 5 hours
Distance = 750 miles
Distance = speed * time
( 2 x 10 )* 5 = 750
10 x + 50 = 750
10 x = 750 + -50
10 x = 700
/ 10
x= 70 mph Car A
Car B 70 + 10 = 80 mph

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
