Answer: $x(x-2)$

Step-by-step explanation:

We have the following expression:

$-x^2 + 2x$

Which can also be written as:

$2x-x^2$

Here, the common factor is $x$ . Hence, if we apply this common factor we will have:

$2x-x^2=x(2-x)$

Then, the factored form is: $x(2-x)$

Divided 80 by my number, and then added 13. The result was 93. What was my number?

igor_vitrenko [27]

The number is 6400.

We have given that,

divided 80 by my number, and then added 13.

<h3>What is the expression?</h3>

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Suppose the number is x

$\frac{x}{80}+13=93$

Subtract 13 from both sides

$\frac{x}{80}+13-13=93-13$

$\frac{x}{80}=80$

Multiply both sides by 80

$\\\frac{80x}{80}=80\cdot \:80$

x=6400

Therefore the number is 6400.

Write an absolute value inequality that describes the acceptable weights, w, of a 20-ounce bottle of sports drink.

Shtirlitz [24]

Answer: $0\leq w\leq 20$

Step-by-step explanation:

Since, Here w represents the weight of the bottle.

And, According to the question, he acceptable weights, w, of a 20-ounce bottle of sports drink.

That is, weight of the bottle can not be higher than 20 or the it can be atleast 20.

Therefore, $w\leq 20$

And, the weight can not be negative.

Therefore, $0\leq w$

Thus, the required inequality is,

$0\leq w\leq 20$
