This table shows a proportional relationship between the number of cups of sugar and flour used for a recipe.

inna [77]

To find the answer for one cup of flour, divide the cups of sugar by the cups of flour. Here’s how it works.

Since we want the proportion for 1 cup of flour, we divide it by itself to get 1.

Thus, we need to have equal sides, so we divide the number of cups of sugar by the amount the cups of flour divided by.

So: 2.5/7.5=1/3

1 cup of flour is proportional to 1/3 cups of sugar.

Hope this helps!

How would you solve 7c + 12 = -4c + 78

Svetach [21]

Hello!

$7c+12 =-4c+78
 \\ 11c=66 \\ 
c=6$

First we will get the variable in the correct side.
add 4c to 7c.
Second thing you will do is subtract 12 from 78

Now, divide 66 by 11 and you'll be left with c=6
