Using average makes these scores seem overall low: because it you add them up and divide them by the quantity you get 61.5 as the average which is low for a quiz grade
2.3+8(1.3x-4.75)=629.9
2.3+10.4x-38=629.9
-35.7+10.4x=629.9
10.4x=665.6
x=64
The last step was --> D. Divide both sides of the equation by 10.4
The first thing we must do for this case is to calculate the area of both yards.
We have then:
front yard:
A1 = (50) * (80)
A1 = 4000 feet ^ 2
Back yard:
A2 = (10) * (30)
A2 = 300 feet ^ 2
"Jayden wants to lay sod on his front yard and on half of his back yard"
Then, the total amount will be:
A = A1 + (1/2) A2
Substituting:
A = 4000 + (1/2) (300)
A = 4000 + 150
A = 4150 feet ^ 2
Answer:
jayden needs to purchase 4150 square feet of sodd
