Rayyan made a $3000 first payment of a car The total cost of a car was $7500 he made 36 equal monthly payments to pay the car in
hammer [34]

Answer:

$125/month

Step-by-step explanation:

<em>equation we got:</em>

7500 = 36x + 3000

<em>subtract</em><em> </em><em>3</em><em>0</em><em>0</em><em>0</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

4500 = 36x

<em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em><em>6</em><em> </em><em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>by</em><em> </em><em>itself</em>

125 = x

x = 125

<em> </em><em>so</em><em> </em><em>rayyan</em><em> </em><em>paid</em><em> </em><em>$</em><em>1</em><em>2</em><em>5</em><em> </em><em>per</em><em> </em><em>month</em>

What is the easiest way to re learn ratios
enot [183]

Answer:

Step-by-step explanation:

Ratios are no different from fractions. They are "comparisons" of 2 or more things. Instead of fraction bars, they use colons to separate 2 different things.

For example:

\frac{1}{2}=1:2

Now, let's do an example problem.

Ex: find the ratio of 5 cats to every dog.

We are comparing 5 cats to every 1 dog, so the ratio is:

5:1

Don't make thing more complicated to yourself, and don't overthink it. They are exactly like fractions. So treat them as such!
