Answer: 6</h3>
=======================================
Work Shown:
1 liter = 1000 mL
3 liters = 3000 mL
I multiplied both sides by 3.
Divide that result over 500 to get 3000/500 = 6
So she'll need to buy 6 cartons.
-------
You could also solve like this:
(1 carton)/(500 mL) = (x cartons)/(3000 mL)
1/500 = x/3000
1*3000 = 500*x ... cross multiply
3000 = 500x
500x = 3000
x = 3000/500 .... dividing both sides by 500
x = 6
<h3>x less than or equal to 5</h3>
Answer:
Yes
Step-by-step explanation:
Remember in order for the rates to be proportional it has to have a constant rate of change and it has to go through the origin if graphed
For one this has a constant rate of change which is 3 dollars per 25 messages
Now we just have to find out if it would go through the origin (0,0)
To do so we subtract 3 dollars and then 25 messages
6-3=3
50 - 25 =25
then again 25-25=0
3-3=0
concluding that (0,0) is a solution
Thus meaning that this is a proportional relationship
