4. in the school band, there are 3 percussion players for every 8 brass instrument players.

answer each letter or at least some of them.

A. 3:8 =x:24. 3 brass:8 percussion. Brass = 3 x percussion
x=9

b. Variables are p= percussion, b = brass

c. b(3)= p

d. Constant of proportionality is 3. Three determines the number of percussion. Increasing the number of brass increases the number of percussion.

e. p = b(3) Constant of proportionality is 3.

f. They relate to each other because either way you use the 3 you will get the constant of proportionality.

Y=3x+1 so the first one
