4. Your classmate says, “If 2x = 3y, then x: y = 2:3” Do you agree with him? Explain your answer.

I don't agree with him

Step-by-step explanation:

2x = 3y

If 2x = a , 3y has to equal a

2x = a

x = a/2

3y = a

y = a/3

Therefore,

x:y = x/y

Or; If 2x = 1 , 3y has to equal 1

2x = 1 , x=1/2

3y= 1 , y=1/3

x/y = (1/2) / (1/3) = 1/2. 3/1  = 3/2

Actually, we did same thing but maybe you can understand better

so, x/y = 3/2 , not 2/3. That's why I don't agree with him

Hope this helps ^-^

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

you can't solve x because it is 2 linear equation and you only have one equation
