Let W = number of white cars, and Y = number of yellow cars.
There were 9 times as many white cars as yellow cars. This means that the number of white cars was 9 times more than the number of yellow cars. This can be translated by the expression:
9Y = W
The person counted 40 cars in total:
W + Y = 40
So we get the system:

In the first equation, we multiply by 9:
9W + 9Y = 360
In the second equation:
9Y= W
W-9Y = 0
Then we add the first with the second equation:
9W + 9Y + W - 9Y = 360
10 W = 360
W = 36
So He counted 36 white cars.
Hope this Helps! :)
Answer:
C. 75 • $6 - $35
Step-by-step explanation:
First, 75 times 6 needs to be in the expression to represent how much they raised from washing the 75 cars.
Then, 35 has to be subtracted because that was the cost of the supplies:
So, C is correct, 75 • $6 - $35

YE ESYE YES VECUAAD ALL OF THEM RMUNERS ARE QUELIATU
0.345 or .345
Step-by-step explanation:
because that is the highest decimal number because it has higher values, I mean "345" is greater than "33", "35", and "332".
the only way the smallest number would be the highest number is when it have a negative symbol to it e.g -0.1 is greater than -0.2 due to the fact that -0.1 is closer to 0,1,2,3,..... than -0.2 According to the number line.
All I'm trying to say is that, if it's not a negative number then the one with the highest value or number is actually the highest number EXCEPT if it Hans the negative symbol (-) to it, then it's the opposite meaning the "smallest number" would be the highest number.
Hope this helps buddy, Good luck ✅.
