The answer to this would be B, C, and E
Answer:
To find how many blocks it would take in each of these scenarios, you could find the total volume and then divide by the volume of each smaller cube.
1. 3/7 x 3/7 x 3/7 = 27/343 cubic inches
1/7 x 1/7 x 1/7 = 1/343 cubic inches
27/343 cubic inches divided by 1/343 cubic inches = 27 cubes.
2. 3/7 x 1/7 x 3/7 = 9/343 cubic inches
9/343 cubic inches divided into groups of 1/343 cubic inches is 9 cubes.
3. 2/6 x 2/6 x 2/6 = 8/216 cubic inches
8/216 cubic inches divided by 1/216 cubic inches is 8 cubes.
Another way to think of it would be for #1, each 3/7 of an inch would be 3 groups of 1/7, so 3 x 3 x 3 for each dimension would result in 27 cubes.
For #2, it would be 3 groups of 1/7, one group of 1/7 and another 3 groups of 1/7, so 3 x 3 is 9 cubes.
For #3 it would be 2 groups of 1/6 three times, so 2 x 2 x 2 = 8 cubes.

Answer:2

<span>B:she could divided both sides by 3 to get x+2=2y</span>
Answer:
One solution is to find x and y by doing the following:
Step-by-step explanation:
Let's solve for x.
3x+2y=4
Step 1: Add -2y to both sides.
3x+2y+−2y=4+−2y
3x=−2y+4
Step 2: Divide both sides by 3.
x=-2/3y+4/3
Lets solve for y.
3x+2y=4
Step 1: Add -3x to both sides.
3x+2y+−3x=4+−3x
2y=−3x+4
Step 2: Divide both sides by 2.
y= -3/2x+2
