fgiga [73]

Answer:

y=40-15x

Step-by-step explanation:

Let x represent the number of hours.

We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:

Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.

We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:

, where, y represents number of miles he has left to travel, after biking x hours.

Scientists on a submarine are investigating Earth's magnetic field.

Contact [7]

Answer:

Net_change_in_depth = 450/7 ft = 64 2/7 ft

Step-by-step explanation:

Missing info attached below

Depth_of_the_frequency_signal = -180 4/7 ft = -1264/7 ft

Depth_of_the_submarine = -116 2/7 ft = -814/7 ft

Net_change_in_depth =

Depth_of_the_submarine - Depth_of_the_frequency_signal

Net_change_in_depth = -814/7 ft - (-1264/7 ft)

Net_change_in_depth = 450/7 ft = 64 2/7 ft
