Answer:

7 balls

Step-by-step explanation:

Look for the worst case scenario:

+1 red ball: 6 + 1 =7

andre [41]

1) Amount of white sugar ÷ the amount of brown sugar =

\frac{2}{3}÷\frac{1}{4}

=\frac{2}{3}.\frac{4}{1}= \frac{8}{3}=2\frac{2}{3}.

2)Amount of white sugar after increase =

\frac{2}{3}+2\frac{1}{2}=\frac{2}{3}+\frac{5}{2}=\frac{19}{6}=3\frac{1}{6}.

3)Amount of flour after increase=2\frac{1}{4}+2\frac{1}{2}=\frac{9}{4}+\frac{5}{2}=\frac{19}{4}=4\frac{3}{4}.

4) Amount of brown sugar =

\frac{1}{4} cup.\frac{1}{4}of\frac{1}{4}=\frac{1}{16}

\frac{1}{16} cup was used .

BEST ANSWER GETS TO BE BRAINLYEST!!!!!
Lera25 [3.4K]
Hey there!

"9 pounds more than" means that you'll be adding 9 to the expression. 

"half the weight w" means that you'll be calculating half of w each time you solve the equation, or 0.5w. 

Your entire expression will be 0.5w + 9. 

Hope this helped you out! :-)
