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 :
If Allison scored 78.5 and Hannah scored 74.65 you’ll subtract 74.65 from 78.5 and get 3.85. That’s how many points more Allison scored
Answer:
x = 12
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
The 2 triangles are similar to the outside triangle and to each other, that is
Δ RQT ~ ΔSRT
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
x² = 144 ( take the square root of both sides )
x = = 12
