The first column is the ratio you start with. The next column in the table should be the reduced fraction. To properly reduce a fraction, you divide the same number on the top and bottom of the fraction. Melody instead subtracted 1 in the top and bottom of the fraction to reduce it. She should have divided the top and bottom by 2 to get the second column of 1 pound of turkey and 3 people served.
The final column is designed to be the answer to the initial question of how many people are fed by 15 pounds of ground turkey. Starting with column 2 (the reduced ratio of 1/3), multiply the top by 15 to get 15 pounds of ground turkey. Then do the same to the bottom of the fraction. 3 x 15 = 45 people fed.
So the table should have been
Pounds of turkey 2 1 15
People served 1 3 45
Melody's overriding error was in believing that adding or subtracting numbers to both the top and bottom of a ratio/fraction keep its value the same. Instead, only multiplying or dividing the top and bottom by the same number creates an equivalent fraction.
I believe the answer is 14. This is a hard one.
A: > greater than
b: > greater than
c: < less than
Equation 1 = 8
equation 2 = 8
equation 3 = 8
equation 4 = 6
so it’s 4 :)
6x+10y=20
10y=-6x+20
y=-6/10x+20/10
y=-3/5x+2
5x-3y=21
-3y=21-5x
y=21/-3+-5/-3x
y=3/5x-7
Two lines are Perpendicular
