Given
One month julia collected 8.4 gallons of rainwater.
she used 5.2 gallons of rainwater to water her garden
6.5 gallons of rainwater to water flowers
Find out how much was the supply of rainwater increased or decreased by the end of the month.
To proof
As given in the question
One month julia collected 8.4 gallons of rainwater
she used 5.2 gallons of rainwater to water her garden and 6.5 gallons of rainwater to water flowers
Total water she used in the month = 5.2 gallons + 6.5gallons
= 11.7 gallons
Let the supply of rainwater increased or decreased by the end of the month
be x .
Than the equation become in the form
x + 8.4 = 11.7
x = 3.3 gallons
Therefore the supply of rainwater increased or decreased by the end of the month is 3.3 gallons.

Answer:
<h2>y = x - 3</h2>
Step-by-step explanation:
4x - 5 = 7 + 4y <em>subtract 7 from both sides</em>
4x - 5 - 7 = 7 - 7 + 4y
4x - 12 = 4y <em>divide both sides by 4</em>
4x/4 - 12/4 = 4y/4
x - 3 = y
Answer:
36 square feet
Step-by-step explanation:
The area of one barrier is the product of the given dimensions:
(9 ft)(2 ft) = 18 ft²
Two such barriers will have twice the area: 36 ft².
This situation can be represented by a step function.If Jalyn purchases 60 shirts the total cost will be $600.At these prices it is cheaper to buy 76 shirts than it is to buy 75 shirts.
