There are six possible outcomes
To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

The reciprocal of 1/6 is 6/1 or 6

The product of reciprocals equals 1
1x = 24
x = 24
To solve, set up a proportion
3.25 cups x cups
---------------- = ---------------
13 servings 28 servings
Now cross multiply
13x = 28 * 3.25
Simplify.
13x = 91
Divide both sides by 13
x = 7 cups
To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
Answer:
A 2(4m + 3) Distribute 8m +6 match
C 8m + 6 This matches
Step-by-step explanation:
18 + 4(m − 3) + 4m
First distribute
18+ 4m -12 +4m
Then combine like terms
8m +6
Now see which expressions match
A 2(4m + 3) Distribute 8m +6 match
D 4(2m + 4) Distribute 8m + 16 no match
B 5m + 19 This does not have 8m no match
E 8m + 16 This does not have 6 as a constant no match
C 8m + 6 This matches
