Answer:
12
Step-by-step explanation:
Let n = the number.
2n - 7 = n + 5
n = 12
Let’s check if we got the right answer by substituting 12 for n into the original equation.
2*12 - 7 = 12 + 5
24 - 7 = 17
17 = 17

Answer:
<h2>
Amount of ounces of candy left = 22ounces</h2>
Step-by-step explanation:
Amount of halloween candy bought by Jack = 5pounds
Amount he gave trick = 3pounds
Amount jack ate = 10ounces
Before we can determine the amount of halloween candy that Jack has left, we need to convert the pounds to ounces in order to make the units consistent.
given 1pound = 16ounces
5pounds = 16* 5 ounces
5pounds = 80ounces
Also;
3pounds = 16*3 ounces
3pounds = 48ounces
Total amount of halloween used up by Jack = 48ounces + 10ounces
= 58ounces
Amount of ounces of candy left = Total amount of candy bought -amount used up
Amount of ounces of candy left = 80ounces - 58ounces
Amount of ounces of candy left = 22ounces
Convert it into fraction=537/100 then do the long division = 5 and 37 over 100
