You are making lemonade. the amount of sugar you need depends on the amount of lemonade mix you use.

cups of sugar
1/3
1
3
packets of lemonade mix
1
3
9
is the amount of sugar you need proportional to the amount of lemonade mix you use? yes or no

The amount of sugar you need is proportional to the amount of lemonade mix you use.

Step-by-step explanation:

Cups of sugar                               Packets of lemonade mix

    1/3                                                             1

    1                                                                3

    3                                                               9

Ratio of packets of lemonade mix to cups of sugar in all cases is 3.

That is

Let us take packets of lemonade mix as L and cups of sugar as S.

We have

                       L = 3 S

So the amount of sugar you need is proportional to the amount of lemonade mix you use.

step-by-step explanation:

i think you should think about the question and not look online.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
