1 answer:

6 0

3 mi/1 hr x 60 mins/1 hr x (how many yards are in a mile)/1 mile put it in fraction form. as i did. and cancel out hrs. and miles. and your left with your yards and mins. multiply across. and you get a huge fraction. divide the bottom number by the top one and you get your answer (: P.S. its really not about the numbers at all. its more about canceling out the conversions to find the answers(:

What is the length of ac help pls

Lelu [443]

Answer:

x=2

Step-by-step explanation:

This is an isosceles triangle you can tell by the two congruent/equal angles

angle A is congruent/equal to angle C by definition the two sides will be equal.

x-4=3x-8

1. get all you x's on one side. by subtracting x from both sides you don't have to deal with dividing by negatives later on.

x-x-4=3x-x-8

-4=2x-8

now you want to get x by itself so add 8 to both sides

4= 2x

x is still not by itself so divide both sides by 2

x=2

Dan made $5000 in taxable income last year.

storchak [24]

well, we know is 10% for the first 7500, but Dan only made 5000 of taxable income, so he's in that range of 0 - 7500, so he only gets to pay 10% of 5000.

$\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{10\% of 5000}}{\left( \cfrac{10}{100} \right)5000}\implies 500$
