Quick I need an answer to this Queston:
fiasKO [112]

Step-by-step explanation:

-  \frac{3}{4} x + 2 \frac{1}{4 } =  \frac{1}{2} x + 1

-  \frac{3}{4} x +  \frac{9}{4}  =  \frac{1}{2} x +  \frac{2}{2}

\frac{ - 3x + 9}{4}  =  \frac{2x + 4}{4}

- 3x + 9 = 2x + 4

- 3x - 2x = 4 - 9

- 5x =  - 5

x =  \frac{ - 5}{ - 5}

x = 1

The answer is C.

How many cubes with side lengths of \dfrac14\text{ cm}
bogdanovich [222]

Answer:

Step-by-step explanation:

Correct question

How many cubes with side lengths of ¼cm needed to fill the prism of volume 4 cubic units?

We know that,

Volume of a cube is s³

V = s³

Where 's' is length of side of a cube

Given that

The cube has a length of ¼cm, and a cube has equal length

s= ¼cm

Then, it's volume is

V = s³

V = (¼)³ = ¼ × ¼ × ¼

V = 1 / 64 cubic unit

V = 0.015625 cubic unit

Then, given that the volume of the prism to be filled is 4 cubic unit

Then,

As, we have to find the number if cubes so we will divide volume of prism by volume of one cube

Then,

n = Volume of prism / Volume of cube

n = 4 / 0.015625

n = 256

So, then required cubes to filled the prism is 256 cubes.

How to write in inqvality
Kitty [74]

Answer:

If you mean "How do I write an inequality?", the answer is COEFFICIENTxVARIABLE {any symbol} COEFFICIENTxVARIABLE >/< INTEGER

In other words, you should have something like this: -3x + 4v < 63

Or this: 51x - 16v > 11

Or anything along those lines.
