2w-1 divided by 5+w+2=2w
FromTheMoon [43]

Answer:

(2w-1)/5+w+2=2w

We simplify the equation to the form, which is simple to understand  

(2w-1)/5+w+2=2w

Reorder the terms in parentheses

( + 0.4w-0.2)+w+2=2w

Remove unnecessary parentheses

+ 0.4w-0.2+w+2=2w

We move all terms containing w to the left and all other terms to the right.  

+ 0.4w+1w-2w=0.2-2

We simplify left and right side of the equation.  

-0.6w=-1.8

We divide both sides of the equation by -0.6 to get w.  

w=3

Devin made 30 custom t-shirts to sell.He will donate 1/8 0f his total sales to a local charity. He sold all 30 t-shirts for $18
V125BC [204]

Answer:

Devin will donate <u>$67.5</u> to charity.

Step-by-step explanation:

Given:

Devin made 30 custom t-shirts to sell.

He will donate 1/8 0f his total sales to a local charity.

He sold all 30 t-shirts for $18 each.

Now, to find the amount Devin donate to charity.

Total number of t-shirts = 30.

Each t-shirts sold at = $18.

So, total amount of 30 t-shirts sold:

30\times 18

=\$540.

As, Devin will donate \frac{1}{8} of his total sales to a local charity.

Now, to get the amount he will donate to charity:

\frac{1}{8} \ of\ \$540\\\\=\frac{1}{8} \times 540\\\\=\frac{540}{8}\\\\=\$67.5.

Therefore, Devin will donate $67.5 to charity.
