Answer:
<em>3/8 of the box cereal</em>
Step-by-step explanation: First you must convert 3/4, 1/8, and 1/4 so they have to same denominator. Four can go into eight two times, so you must multiply the numerator by two. So your new fractions are 6/8, 1/8, and 2/8. Now you must subtract 1/8 and 2/8 from 6/8. When you subtract 1/8 from 6/8 you get 5/8. Now subtract 2/8 from 5/8 and you get <em>3/8. </em>That is how you get the answer, I hope this helps you.

<u>ANSWER</u>
A. (4,12)
<u>EXPLANATION</u>
The equations are:
and
To eliminate a variable we make the coefficients of that variable the same in both equations.
It is easier to eliminate x.
We multiply the first equation by 2 to get:
We add equations (2) and (3).
Divide both sides by 23
Put x=4 into equation (1).
The solution is (4,12)
Answer:
4
Step-by-step explanation:
Answer:
19$
Step-by-step explanation:
In this problem, we have to apply the rule of three. Also, we must have present that $15.20 is the 80% of the price, because the store offers a 20% of discount. So, if $15.20 is 80%, how much would be the 100%?
Therefore, the original price of the pants is $19.
Remember that we must identified the right proportion to apply the rule of three, in this case, that proportion is the 80% with 15.20, that's the reason or fraction center of the whole operation.
