Answer:

3\left(5+4y\right)+8-2y=10y+23

Step-by-step explanation:

Given

As the expression is given by

3(5+4y)+8-2y

To determine

Simplify the expression

Let us simplify the expression

3(5+4y)+8-2y

Expand 3(5 + 4y) = 15 + 12y

3\left(5+4y\right)+8-2y=15+12y+8-2y

grouping like terms

                              =12y-2y+15+8

                              =10y+23

Therefore,

3\left(5+4y\right)+8-2y=10y+23

NEED HELP ASAP PLEASE!!
ehidna [41]
\dfrac{ \frac{4}{4 - x} +  \frac{5}{x - 4} }{ \frac{5}{x} +  \frac{2}{x - 4} } =

=\dfrac{ \frac{-4}{x - 4} +  \frac{5}{x - 4} }{ \frac{5(x - 4)}{x(x - 4)} +  \frac{2x}{x(x - 4)} }

=\dfrac{ \frac{5-4}{x - 4} }{ \frac{5(x - 4) + 2x}{x(x - 4)} }

=\dfrac{ \frac{1}{x - 4} }{ \frac{5x - 20 + 2x}{x(x - 4)} }

=\dfrac{ \frac{1}{x - 4} }{ \frac{7x - 20}{x(x - 4)} }

=\dfrac{1}{x - 4} \times \dfrac{x(x - 4)}{7x - 20}

=\dfrac{x}{7x - 20}

You buy 24 keyboards for $120 each less 15%. What is your subtotal before taxes?
kotykmax [81]
<span>First, you need to take the 15% off from the $120 so it will make it easier for you to calculate later. Since there is 15% off, your $120 becomes only $102. Since your keyboards only costs $102 each now, you just have to multiply the number of keyboards you wanted to the less price. $102 multiplied by 24 keyboards is equals to $2,448. We don’t have to add taxes because it is stated that we are just looking for SUBTOTAL before taxes. The answer is A. $2,448. <span>
