Suzi starts her hike at 240 feet below sea level. When she reaches the end of the hike, she is still below sea level at - 143 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the
hike?

383ft

Step-by-step explanation:

Given parameters:

  Elevation = 240ft at the start

  Elevation at the end = -143ft

Unknown:

Change in elevation:

Solution:

The change in elevation is the difference between the two hiking milestone;

  change in elevation = Elevation at the start  - Elevation at the end

                                    = 240ft  - (-)143ft

                                   = 240 + 143

                                    = 383ft

2 x t divided by n

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
