Answer:
x <3
Step-by-step explanation:
13x-4 < 12x-1
Subtract 12x from each side
13x-12x-4 < 12x-12x-1
x-4 <-1
Add 4 to each side
x-4+4<-1+4
x <3
Answer:
3 gallons at 3 dollars a piece
Step-by-step explanation:
2.25 •6=13.50
4.50•3=13.50
13.50+13.50= 27.00
36-27=9
9÷3=3
Answer:
441
Step-by-step explanation:
If the faster car is travelling 20 mph faster then slower car then the speed of slower car is 55mph and faster car is 75 mph.
Given that the faster car is travelling 20 mph faster than slower car and when slower car travels 165 miles the faster car travels 225 miles.
We are required to find the speed of slower car and faster car.
let the speed of slower car be x mph.
In this way the speed of faster car be (x+20) mph.
Speed=Distance/ time
We have to first take slower car.
x=165/Time
Time=165/x-----------1
Now by taking faster car.
x+20=225/time
Time=225/(x+20)-------2
From equation 1 an equation 2.
165/x=225/(x+20)
225x=165x+3300
225x-165x=3300
60x=3300
x=55 mph
Faster car=55+20
=75 mph.
Hence if the faster car is travelling 20 mph faster then slower car then the speed of slower car is 55mph and faster car is 75 mph.

Q. Can we set up an equation 2x = 8 in question number 2 ?
Ans : Yep! Since the diagonals of parallelogram bisect each other , you can :) When we solve 2x = 8 , we obviously get x = 4.
