868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.
Answer:
Box E has a greater volume than Box D.
Step-by-step explanation:
Step 1 : Find the volume of Box D.
The formula for volume of a rectangular prism such as this is
height * width * depth
Knowing this, let's substitute the values.
3 * 5 * 1 = 15
The volume of box d is 15 cubic units.
Step 2 : Find the volume of Box E.
height * width * depth
4 * 4 * 1 = 16
The volume of box e is 16 cubic units. Therefore box E has a greater volume than box D.
Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.
As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.
in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.
7x+4<46
7x+4(-4)<46(-4) <- Subtraction Property of Equality
7x<42
7x(/7)<42(/7) <- Division Property of Equality
x<6
I hope this helps!
