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
The rule of going from (x,y) to (x-4,y) will have the point move 4 units to the left. The point will not move up or down.
Answer:
18
Step-by-step explanation:
Distribute the 7 to get 273=14n+21
Subtract 21 to get 14n=252
Divide by 14 to get 18
Turn it into a proper fraction or even a decimal number.
For instance 13/2 = 6 1/2 or 6.5 which you can see would be between 6 and 7.
