The tub holds 43 gallons.....it contains 18.....(43 - 18) = 25....so it needs 25 gallons.....after 5 minutes, the tub is full.....so it fills at a rate of 25/5 = 5 gallons per minute
y = 5x + 18....where y is the total gallons and x is the number of minutes
but we need it in standard form....
y = 5x + 18
-5x + y = 18
5x - y = -18 <== standard form
.99 cents for one liter . you do this by dividing by 2
Answer:
9 over 14 Is the answer.........
Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5
Hope this helped!
