Gerardo says that a cube with edges that measure 10 centimeters has a volume that is twice as much as a cube with sides that mea
irga5000 [103]
He is wrong.
The 10 inch cube is bigger than the 5 inch cube by 5 cm in EACH DIRECTION.
So, the 10 inch cube should be twice as big in volume by a factor of 2*2*2
=8
Okay let's see.
5 cm cube volume = 5*5*5 = 125 cc
10 cm cube volume = 10 * 10 * 10 = 1,000 cc

1,000 / 125 = 8

What is X?<br><br> 2.3x-8.7=0.8x-4.2<br><br> pLS hELP
daser333 [38]

Answer:

x = 45/17

Step-by-step explanation:

We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.
