Mark dug a 20 foot hole in 4 hours. which rational number shows the average depth mark dug each hour?

5:1

The ratio would be 20:4 (foot to hours) and when simplified, it would be 5:1

Mark dug 5 ft for every hour

Step-by-step explanation:

20 ft in 4 h

20ft = 4h

20ft/4 = 4h/4

5ft = h

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
