Scrat [10]3 years ago

To solve this, we must isolate x (have it by itself).

4/5x = 56

Multiply each side by 5x.

4/5x(5x) = 56(5x)

Divide each side by 280.

4/280 = 280x/280

Solve.

0.014 = x

0.014 can also be written as 1/70

1) In class you worked with a "big" cube made of 27 smaller cubes each of which was 1 cmby 1 cm by 1 cm. Suppose you had 150 of
abruzzese [7]

The information provided is that you have smaller cubes that measure 1 cm on either of the three sides. In order words if you lie each cube side by side you would have the length/width/height of the indicate sides.

For a cube made up of 27 smaller cubes, you can determine the length of each side by factoring the entire size provided. That means for a cube made up of 27 smaller cubes you would have;

27=3\times3\times3

This means you would have 3 smaller cubes on the length, 3 smaller cubes on the width and 3 smaller cubes on the height.

Therefore, if you now have 150 of the smaller cubes, by factoring this you would have the following possibility;

\begin{gathered} 150=2\times3\times5\times5 \\ 150=6\times5\times5 \end{gathered}

This means you would have one side (length) 6 cubes, on another side (width) 5 cubes and on the third side (height) 5 cubes.

That means with 150 smaller cubes you could make a cube with the dimensions,

\begin{gathered} \text{Length}=6\operatorname{cm} \\ \text{Width}=5\operatorname{cm} \\ \text{Height}=5\operatorname{cm} \end{gathered}

ANSWER:

The largest big cube you could make would be a 6 cm by 5 cm by 5cm big cube

Answer:
Third choice is the correct one

Explanation:
No fraction can have a denominator = 0 because this would make it undefined.
Therefore, the solution would be all the real values except for those that make the denominator = 0
Let's check the terms in the denominator:
i. c-3 = 0 at c = 3
ii. c = 0
iii. c(c-3) = 0 at c = 0 or c = 3
Therefore 0 and 3 are the values that would make the denominator zero.

Based on the above, the solution is all real numbers except 0 and 3

Hope this helps :)
