Frank has devised a formula for his catering business that calculates the number of meatballs he needs to prepare. The formula is m=ra+2c, where c= number of children;m = meatballs; a = number of adults. How many meatballs are required for a party of 20 adults and 5 children?

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3

If is congruent to,then m is the midpoint

This law is sometimes called the grouping property. as you can see, regardless of how the numbers are grouped, the answer is still 13. the associative law of multiplication is similar to the same law for addition. it says that no matter how you group numbers you are multiplying together, you will get the same answer.
