The ratio of Alex’s toy cars to Jim’s toy cars is 8:3. How many toy cars do they have altogether, if Alex has 40 more cars than Jim?
Answered by Reiny
Alex has 8x of them
Jim has 3x of them
8x - 3x = 40

carry on

But Alex has forty MORE. How would 8x-3x be equal to that?
Answered by Reiny
Umhh, if Alexa has 40 more, wouldn't the difference between their amounts be 40???
Why don't we solve my equation?
8x - 3x = 40
5x = 40
x = 8

I defined Alex's numbers as 8x , so 64
and I defined Jim's amount as 3x, so 24

doesn't Alex have 40 more than Jim???

Guys just add 24+64 and you get 88
Answered by henry2,
Jim has X cars.
Alex has x+40 cars.

(x+40)/x = 8/3.
3x+120 = 8x
8x-3x = 120
X = 24.
x+40 = 24+40 = 64.

Answered by sure
7x-20=3x+20
4x=40
x=10

subsitute 10 with x
70+30 =100!!!!!!!
It is correct
