Evaluate v+t when t=4x-1 and v=2x+1

Rainbow [258]

You would simply add the last two equations together. If v=2x+1 and t=4x-1, you can add them up. This would make 2x+1+4x-1. If you combine like terms, 1 and -1 cancel out and you are left with 6x. This means x can be anything.

Answer:

The seagull's position halfway is 85.5 feet.

Step-by-step explanation:

The seagull is at 125 1/2 feet above the sea level.

The fish is at 45 1/2 feet below the sea level.

The distance between the seagull and fish = seagull's distance above the sea level + fish's distance below the sea level

= 125 1/2 + 45 1/2

= $\frac{251}{2}$ + $\frac{91}{2}$

= $\frac{342}{2}$

= 171

The distance between the seagull and fish is 171 feet.

Since the seagull stops halfway, then;

seagull's position = $\frac{171}{2}$

= 85.5

The seagull's position halfway is 85.5 feet.
