The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:
lisabon 2012 [21]

Answer:  The speed of the motorboat is 70 miles per hour

Step-by-step explanation:  Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.

For example, at 2 hours, the distance shown on the graph is 175 miles

Subtract: 175 -35 = 140.  Then divide 140/2 = 70

At 4 hours, the distance shown is 315 miles.

Subtract: 315 - 35 = 280. Then divide  280/4 = 70

70 mph is the speed.

I need a normal answer not a equation
Sloan [31]

Answer:

PQ = 3.2

Step-by-step explanation:

You must use the addition property of equality, and subtract 16 from the of the 5x, and add it to the other side.

After that, you have 5x = 16

You then divide both sides by 5.

5x/5 = 1x = x

16/5 = 3.2

x = 3.2

Therefore, the side 'PQ' is equal to 3.2
