D=vt,   distance is equal to velocity times time.

4v+3(v+3)=149 perform indicated multiplication

4v+3v+9=149  combine like terms on left side

7v+9=149  subtract 9 from both sides

7v=140  divide both sides by 7

v=20

So the ship traveled at a speed of 20 mph when heading east.

lesantik [10]

Answer:

Freddie would have walked 25 miles after 12 and a half hours.

Step-by-step explanation:

Given that Freddie is walking at a constant speed, and after 2 hours he walked 4 miles, while after 4 hours he walked 8 miles, to determine how long he walked 25 miles, the following calculation must be performed:

4/2 = Miles per hour

2 miles per hour

2X = Y

2X = 25

X = 25/2

X = 12.5

Therefore, Freddie would have walked 25 miles after 12 and a half hours.

The answer would be y = 3.1

19.9 + 8 = 9y
