How many cups of flour are needed to make 3 dozens of dinner rolls

1/15

Step-by-step explanation: A. If 1/3 cup makes 5 rolls, you need to know how many cups make one. (1/3)/5 = 1/15  Take the number of cups for one roll and multiply it by 3.  1/15 x 3  Final Answer = 3/15

B. Take the number of cups you have divided by 1/3 (since you know how many roles this makes)  (5 2/3) / (1/3)  Final Answer = 17

C. Well, we already solved for this one in A, didn't we?  Final Answer = 1/15

-56 or b.

Step-by-step explanation: -6+(-73)=-79 because the negative number means minus.

-79+(positive)56=-23 because a negative number plus a positive number is adding the positive number meaning you subtract but keep the negative sign

-23+(-33)=-56 because the negative number means minus

I don't know how to explain that is just kind of how it works.

But here's something for the future.

Positive+(Negative) is minus

Positive+Positive is plus (duh)

Negative plus negative is minus (or add but theres a negative sign)

Negative-negative=plus (idk why but its meth)
