Question

Help please I'm stuck once again?​

Answer 1

The probe's final position is -143m

Explanation:

Note that the words 'lowered' and 'below' mean subtract; while the word 'raised' means add. Thus, interpreting the statement to mathematical expression is done below.

`- 90m + 50m - 138m + 35m`

`= - 143m`

Therefore, the probe's final position is -143m. Hence, the sensor is 143m below the sea level.
