Answer:
1 3/4 cups
Step-by-step explanation
Since the recipe calls for 5 1/2 cups of flower and Molly only has 3 3/4 cups, subtract 3 3/4 from 5 1/2 to get the remaining cups of flour needed to make the recipe.
5 1/2 - 3 3/4 = 1 3/4
15+c=17.50
First you subtract 15 by 15 because you switch operations from adding to subtracting then you would put C under it
Second subtract 17.50 and 15 and that is 2.50 so C= 2.50
Answer:
C = 2
Step-by-step explanation:
9c + 14 = 2c^2 + 9c + 6

-6 -6
8 = 2c²
4 = c²
c = 2
