So you first want to distribute the 12 into what is inside the parentheses. Then after that all you need to do is simplify!

Answer:
<h2>34 earrings</h2>
Step-by-step explanation:
Step one:
given that the total lenght of the wire is 25 1/2 inches
in decimal, this is 25.5 inches
we are told that each earring requires 3/4 in of wire
in decimal this 0.75 in
Step two:
<em>The number of earrings that can be mad is found by dividing the total length of wire by the length needed to make one earring</em>
The number of earrings that can be made is given as
=25.5/0.75
=34 earrings
You would take 10.85 times .4% which gives you 4.34 then you would add 4.34 to 10.85 for a total of 15.19
The phrase “the difference between a number and 5” as a variable expression would look like: x - 5
