Question 2. A submarine at -38 feet dives 50 feet. What is the submarine's
elevation after the dive (in feet)?

-88 ft

Step-by-step explanation:

When diving you are going further below sea level. anything below sea level is negative thus the equation is -38 - 50 which gives you the answer of -88 ft

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
