Rita can make 144 earrings in 3 hours. I multiplied 12 times 4 which equals 48, then times 48 by 3 and got 144.

In 1/4 of an hour, Rita makes 12 pairs
so in an hour, Rita makes 48 pairs, since 4 x 12 = 48


48 x 3 = 144 pairs, since she makes 48 pairs in 1 hour, you want to find how much she makes in 3 hours

144 pairs is your answer

hope this helps

 solve for x x/9−5=5<br><br>x=​
gregori [183]

Answer:

<u>x=90</u>

Step-by-step explanation:

<em />

<em>Let's solve your equation step-by-step.</em>

x/9−5=5

<em>Step 1: Simplify both sides of the equation.</em>

x/9−5=5

1/9x+−5=5

1/9x−5=5

<em>Step 2: Add 5 to both sides.</em>

1/9x−5+5=5+5

1/9x=10

<em>Step 3: Multiply both sides by 9.</em>

9*(1/9x)=(9)*(10)

x=90

Answer:

<u>x=90</u>
