Answer:
On problem one the answer is 4 but I'm not sure about the second problem
The formula to finding the volume would be v=l•w•h so then insert the values into that. You’re left with v=10•8•5. Multiply them together and you get 400cm cubed. That’s how much sand you’d need to fill the box.
The first one you have 
=
. To solve this you would multiply both sides by 3.
=x
Then simplify by dividing the numerator and denominator by 3.
=x (or in a mixed fraction 1
)
The second one you have 
=
. To solve this you would multiply both sides by x.
x=3
Now you would divide both sides by .
x=
You now then multiply 3 by 24 and then divide by 7.
x= (in a mixed fraction would be 10
)
Answer:
12
Step-by-step explanation:
D because 3/4 is .75 so 7.75 divided by .75 equals 10.333333333333333
