Answer:
-2x+3
Step-by-step explanation:
Gradient is change in y over change in x
=2
and then
+3 because that's where it cuts the Y axis
The graph should look like the below image
It’s a straight line that passes through the origin.
1/2 = 3/6
5 gallons of water changed it to 5/6, so that would mean 2/6 would be 5 gallons worth.
5 x 3 = 15.
Hope this helps.
Answer:
200$
Step-by-step explanation:
In this case, we already know the ratio between the savings and the spendings and it's 3:5.
This means that for every 3$ saved, Sam spents 5$.
Then, we only need to do a simply rule of 3, to stablish the amount spended.
If:
120 ---------> 3
X ------------> 5
Solving for X, we have:
120/X = 3/5
X = 120 * 5 / 3
X = 600 / 3
X = 200$
If you want to verify that this calculation is correct, then do the ratio between 120 and 200. If the ratio is 3:5 is correct. Here's the demostration:
120/200 --->simplified by 10: 12/20 ------->simplified by 4: 3/5
