7x+4=60

7x=60-4

7x=56

x=56/7

A prism is completely filled with 2304 cubes that have edge length of 14 cm
Gemiola [76]
All we have to do is find out the volume of all the cubes to get the volume of the prism.

So since cubes are just 3D squares all of their sides are the same.

So for one cube, determining the volume is just 14^3 (length * height * width), which is 2744.

Now we just multiply 2744 by 2304 and we get: 6322176.

And so the answer is 6322176 cm^3.

This can be shown with this equation:
2304 * (14)^3=x

Where x is 6322176.

I hope this helps! (Also if you could give brainliest, I would really appreciate it!)

2(2x +1) = 3(x-8) =<br>how do you solve this ​
saw5 [17]

Answer:

x=-26

Step-by-step explanation:

Distributive property first (both sides)

you would get

4x+2 = 3x-24

next you will subtract 3x from both sides

1x+2=-24

add 24 to both sides

1x+26=0

move 26 to the other side but since you flipped it you have to make it negative

x=-26

Soon-Jin sent out 48 invitations, this was 4/5 of all her invitations. How many invitations will she send out in total?
stepladder [879]
If 4/5 of the total is 48, the total can be found by dividing it by 4 and multiplying it by 5:
48/4 = 12
12*5 = 60.
