Answer:

To fill the sandbox, she would need 15 cubic feet.

Step-by-step explanation:

To find the volume of a box, multiply all of its dimensions together.

6ft * 5ft * 1/2ft = 15ft^3

So, since she bought 20 cubic feet of sand, she should have enough with 5 cubic feet left over.

Answer:

-9 = 0.45m

Step-by-step explanation:

$0.45m - 9 = 0.9m$

^ Subtract 0.45m from BOTH sides. so $0.9m - 0.45m$ ... etc
Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
That will equal to:

$-9 = 0.45m$ <-- ANSWER
