Question

A seal went 15 feet below sea level to catch a fish. A sea lion dove 6 feet less than two times as deep as the seal to catch a larger fish. What expression represents the sea lion's position in relation to sea level? 2 times 15 minus 6 15 minus 2 times 6 2 times (negative 15) minus 6 2 times (negative 15) minus (negative 6)

Answer 1

D is the sea lion's

Explanation:

Answer 2

`(2 * (-15))-(-6)` is the sea lion's position in relation to sea level

Explanation:

Given:

Distance of seal below the sea level = 15

Distance of lion below the sea level = 6 feet less than two times as deep as the seal

To Find:

Expression representing the sea lion's position in relation to sea level = ?

Solution:

Distance of lion below the sea level = 6 feet less than two times as deep as the seal

Two times as deep as the seal

=>
`2 * \text{position of seal}`

=>
`2 * 15`

But it is 6 feet lesser

=>
`(2 * 15)-6`

Since it is below the free level, we use negative symbol

So the position of the lion in relation to the sea level is

=>
`(2 * (-15))-(-6)`
