Okay so each person is $12
Then you need to times that for how many people are in the car x.
Since x is a variable and not a number it can go right next to the 12
You answer should be 12x
The common denominator for 25 and 20 would be 100
25 x 4 = 100
20 x 5 = 100
Rewrite 14/25 as 14 x 4 / 25 x 4 = 56/100
Rewrite 11/20 as 11 x 5 / 20 x 5 = 55/100
14/25 is greater than 11/20
14/25 > 11/20
4n - 3= -2n + 9
add 3n to both sides
4n= -2n +12
add 2n to both sides
6n= 12
divide both sides by 6
n= 2
Check:
4n-3=-2n+9
4(2)-3= -2(2)+9
8-3= -4+9
5=5
Hope this helps! :)
