Answer:
Total weight of gravel on the roof = 
Step-by-step Explanation:
The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.
We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.
Area of rectangle = L*W
Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area to be covered with gravel = 
Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered = 
Answer:
12k in 8 minutes, 18k in 12. it would be 15k if you take away 2 minutes.
Step-by-step explanation:
The smaller number is 15 and larger number is 36.
Step-by-step explanation:
Let,
Smaller number = x
Larger number = y
According to given statement;
The sum of two numbers is 51.
x+y = 51 Eqn 1
Four times the smaller number is 24 more than the larger number.
4x = y+24
4x - 24 = y
y = 4x-24 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
Dividing both sides by 5
Putting x=15 in Eqn 2
The smaller number is 15 and larger number is 36.

Answer:
the y value equals 5
Step-by-step explanation:
(x,y)so
plug in 8 for x
5(8)=40
40 -2y=30
subtract 40 from both sides
-2y=-10
divide by -2
y=5
The answer would be a^9 (a to the ninth power) because you would add the exponents.
