A)
d =240/a
B) 2 loads of gravel
Step-by-step explanation:
Step 1:
Given one load of gravel is 240 ft2.
We have depth = 240/area
Hence the inverse variation model is d =240/a
Step 2 :
The length and breadth of the playground is 40 ft and 24 ft
The depth of the playground is 6 in = 6/12 ft
Hence the volume of the given playground is 40 * 24 * 6/12 = 480 cu ft.
There is 240 ft2 of gravel in one load
So we need 480 cu ft of gravel = 480/240 = 2 loads of gravel.

Answer:
no solution
Step-by-step explanation:
3(x+5) +2x=10x-5(x+1)
Distribute
3x+15 +2x = 10x-5x-5
Combine like terms
5x+15 = 5x -5
Subtract 5x from each side
5x-5x+15 = 5x-5x-5
15 = -5
This is never true so there is no solution
Answer:
Answer: It's relatively easy to find x in this problem. 4x+3y=12 means that the expression 3y needs to be 12 too, which gives us 12-6 or 6. That number divided by 4 is 2, so x=2! Congrats, you've found x!
Step-by-step explanation:
One way of solving this problem is to remove the parentheses all together and write the equation as 8x+6y = 54. Subtracting 54 from both sides would give us -8x + 6y = 18. The key point here is that when subtracting a negative number, we have to borrow one from our variable so instead our answer becomes (-8)x-6(y)=-54.
