A box of 12 markers costs $16.20. Calculate the cost of one marker?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

step-by-step explanation:

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
