Answer:
y=6-3x
Step-by-step explanation:
first subtract 9x from 9x+3y=18
-9x -9x
so you get 3y=18-9x or 3y=-9x+18 then divide both sides by 3
so you get y=6-3x hope this helps :)
You would put it up into proportions so 33 over 55 equals x over 100. Then you would cross multiply so 55x=3300. Then you would divide 3300 by 55 and get 60%.
Answer:
Each person paid $24.
Step-by-step explanation:
1. Find 20% of 40. Since 20% is equal to 1/5, we can divide 40 by 5 to get 8. Together they tipped $8.
2. We know that the total amount they paid was $48, so we divide that in half to get the answer. 48 divided by 2 is 24.

Let the length of the rectangle is x inches
Hence, the width is (x/2)+4 inches
Thus,
Divide both parts of the equation by 3:
Answer:
The best way to show and explain direct proportional relationships is by graphing two sets of related quantities. If the relation is proportional, the graph will form a straight line that passes through the origin.
