What is an expression to represent the equation
Tatiana [17]

Answer:

8 + \frac{x}{4}

Step-by-step explanation:

I'm assuming you want an answer to the top section of the question.

We can start with 8.

    8

When a problem asks for the sum, it's looking for addition, so we use the + sign.

    8 +

The problem says "a number," so let's represent that with x. Basically, x just means a number we don't know.

    8 + x

The "number" is divided by 4, so we'll just put x/4 as our second term.

   8 + \frac{x}{4}

Factor 4x^4yz-16y^3z
Iteru [2.4K]

Answer:

<h2>4x⁴yz - 16y³z = 4yz(x² - 2y)(x² + 2y)</h2>

Step-by-step explanation:

4x^4yz-16y^3z\\\\4x^4yz=4yz\cdot x^4\\\\16y^3z=4yz\cdot4y^2\\\\4x^4yz-16y^3z=4yz\cdot x^4-4yz\cdot4y^2=4yz(x^4-4y^2)\\\\x^4-4y^2=x^{2\cdot2}-2^2y^2=(x^2)^2-(2y)^2=(x^2-2y)(x^2+2y)\\\\Used:\\\\(a^n)^m=a^{nm}\\\\(ab)^n=a^nb^n\\\\a^2-b^2=(a-b)(a+b)\\\\4x^4yz-16y^3z=4yz(x^2-2y)(x^2+2y)

Ella collects 50 bottles to recycle. Of the bottles she collects, 19 are plastic and the rest are glass.
nekit [7.7K]
QUESTION A

The total number of bottles Ella collected is
50


The number of bottles that are plastic is

19

The percentage of bottles that are plastic is

=  \frac{number \: of \: plastic \: bottles}{total \: number \: of \: bottes}  \times 100\%

=  \frac{19}{50}  \times 100\%

= 19 \times 2\%
= 38\%

Therefore 38% of the bottles are plastic.



QUESTION B

The total number of bottles that are glass is
50 - 19 = 31

The total number of bottles Ella collected is
50

The percentage of bottles that is glass is
=  \frac{number \: of \: glass \: bottles}{total \: number \: of \: bottles}  \times 100\%

=  \frac{31}{50}  \times 100\%

= 31 \times 2\%
= 62\%

Therefore 62% of the bottles are glass
