Hiya there!
If the recipe provided says that we need two cups for three gallons of punch, then you need 2/3 of a cup for one gallon.
I know this because if you add 2/3+2/3+2/3 (or multiply 2/3×3), you get the whole integer 3.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
Answer: The correct answer is: " 4c ".
__<u>_________</u>
<u>Step-by-step explanation</u>:
" 4c * d ÷ d " =
" (4c*d) /d " ;
= " (4cd) /d " ; The "d's" cancel out to "1" ; since "d ÷ d = 1 " ;
and we are left with: " 4c " .

Use f and m for "female" and "male." Then f = m + 16, and f + m = d (total)
So now we have the system of linear equations
f = m + 16
f + m = d
We can eliminate f by subst. m + 16 for f in the second equation:
d-16
m + 16 + m = d, or 2m + 16 = d. Find m. 2m = d - 16, so that m = --------

Assuming that the male horses are either brown or black, and that 25% of these are brown, then the rest must be black. This number is
d-16
