<span>During the distribution of bonbons to her grandchildren, Grandma Claudia realized that if she distributed 11
chocolates for each of them, 10 candies would remain. In the meantime, distribute 13 chocolates
each of his grandchildren, would lack 6.
Based on this information, it is CORRECT to state that the difference between the number of candies
and the number of grandchildren is
A) 90.
B) 30.
C) -90.
D) -30.
Let n=number of candies, and c=number of grandchildren The story expressed in modulo gives the two following equations: then mod(n,11)=10 (ten left if each given 11).............(1) mod(n,13)=-6, or mod(n,13)=7 (7 left if each given 13)
By enumerating (1), we have 10,21,32,43,54,65,76,87,98,109... => 8*11+10=98 By enumerating (2), we have 7,20,33,46,59,72,85,98,101... => 8*13-6=98 Hence there are 8 grandchildren and 98 candies.
The difference of the number of candies and the number of grandchildren is therefore 98-8=90.
Another way to get the number of grandchildren is c=(10-(-6))/(13-11)=8
In math, the word difference is the result of subtracting one number from another. It refers to the difference in quantity between two numbers. In math, we get the difference between two numbers by subtracting the subtrahend (the number being subtracted) from the minuend (the number being subtracted from).
you will first take the the 3 and do the opposite and subtract it from both sides so it should look like this when u solve a-2=-5 then u will take the two and do the opposite and add it to both sides so the answer is (a=-3)
