Which pair of numbers is relatively prime? 7 and 21 4 and 15 6 and 9 9 and 27

i used to know how to do this in 7th but i forget easily

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
