x = hours
car 1 left an hour before car 2 so you have 55(x+1)
car 2 = 75x
add them together to equal miles driven:
55(x+1) + 75x = 380
55x+55 + 75x = 380
combine like terms:
130x+55 = 380
subtract 55 from each side:
130x = 325
divide both sides by 130
x = 325 /130 = 2.5
x = 2.5 hours
so 2.5 hours
Answer:
Step-by-step explanation:
4m - 8 = 10 - 2m
6m - 8 = 10
6m = 18
m = 3
No. The line just has to go below ' 1 '.
1a=3.04
2a=30.4
3a=304
4a=3040
6/2=3
The scale factor is 3
3x3=9
w=9
