An experienced computer technician can set up a network in 12 hours. it would take an intern 20 hours to set up the same network. if they work together, how long will it take to set up the network?

i need to know how to find the rate that they work

i need to know how long it will take if they work together

It would be: 1/20+1/12 = 3+5 / 60 = 8/60 = 4/30 = 2/15 = 7.50 hours

so, your answer is 7.50 hours

ik how do do this just give me a few minutes and i will give it to

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
