Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot
MrMuchimi

Complete question :

Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall. Find the number of block letters that will fit in the box.

Answer:

1/2

Step-by-step explanation:

Number of block letters that will fit in :

Volume of box ÷ volume of each letter cube

Volume of each letter cube = (side length)³ = (2/3)³ = 8/27 ft³

Volume of box = length * width * height

Volume of box = 1 1/3 * 2/3 * 2/3

Volume of box = 4/3 * 2/3 * 2/3 = 16 / 27 ft³

Therefore ;

8/27 ÷ 16/27

8/27 * 27/16

= 8/16

= 1/2

1.   x+5y=8
    2x- 5y=1     What you do is find the number/variable that are the same( here is is the +5y and -5y. You want them to be opposites(-,+) so that they cancel each other out. if they are not opposites, then multiply one equation by a negative sign to change it. Cross out the 5y's. Now you can combine like terms-x+2x=3x, and 8+1=9, so now your equation will look like this:
3x=9
x=9/3
x=3
now take x=3 and plug it into the first equation to solve for y. x+5y=8, so 3+5y=8
5y=8-3
5y=5
y=5/5
y=1
(3,1) are your answers.
now do the same with the other problems.
