T= 21.79x + 3.99x + 6.89x where t is the total cost and x is the number of brushes/rollers/paint cans you buy. You don't need a different variable for each item because you buy the same amount of each.
Answer:
y = 3/4 x + 25/4
Step-by-step explanation:
just tried the numbers out with desmos (free online software
the 3/4 where guessedby intuition
(would indeed appreciate the brainliest if you appreciate the work)
last one because you can solve it to many way6s
Set equal to 0
3=0, nope
3y-12=0
add 12
3y=12
divide 3
y=4
5p-4p-8=-2+3
p-8=1
p=9
