Answer:
Each eraser costs $2.00
Step-by-step explanation:
<u>Step 1: Make an equation</u>
4 + 5a = 14
4 = shows that cost for one magazine
5a = shows that 5 erasers cost a each
14 = total price
<u>Step 2: Solve for a</u>
Subtract 4 from both sides: 4 + 5a - 4 = 14 - 4
Divide by 5 from both sides: 5a / 5 = 10 / 5
Answer: a = 2
Part A:
First, we will need to compute the area of the lawn.
We are given that the lawn is a rectangular plot with dimensions 60 ft and 90 ft.
Area of rectangle = length * width
Area of lawn = 60 * 90 = 5400 ft^2
Now, we will compute the number of ounces.
We are given that:
<span>Each ounce of grass seed will cover 120 square feet. Therefore, to know the number of ounces needed to cover 5400 square feet, all we have to do is cross multiplication as follows:
1 ounce ---------> 120 square feet
?? ounce --------> 5400 square feet
Number of ounces needed = (5400*1) / (120) = 45 ounces
Part B:
We know that one ounce is equivalent to 0.0625 pounds.
For the lawn, we need 45 ounces, this means that:
number of pounds needed for the lawn = (45*0.0625) / (1) = 2.8125 pounds
which is approximately 3 pounds.
We know that each bag weighs one pound, therefore:
number of bags needed = 3 bags

Answer:
y = 7
Step-by-step explanation:
Subtract 9 from both sides.
-7 = -y
Divide both sides by negative 1 (or multiply by negative 1).
7 = y
So, in mathematical terms, y = 7.
Hope this helps! :)
