Elevator 1 in an office building moved from ground position to a final position of +12 feet. elevator 2 in the same building moved from ground to a final position of −15 feet. which statement best describes the final positions of these two elevators? elevator 1 is 12 feet above ground level, and elevator 2 is 15 feet below the position of elevator 1. elevator 1 is 12 feet below ground level, and elevator 2 is 15 feet above the position of elevator 1. elevator 1 is 12 feet above ground level, and elevator 2 is 15 feet below ground level. elevator 1 is 12 feet below ground level, and elevator 2 is 15 feet above ground level.

Step-by-step explanation:

Let's break this down step-by-step

This is just a simple addition problem

0 + 12 = 12

Elevator 1 is 12 feet above ground level

This time, we use subtraction, since it is -15 feet

0 - 15 = -15

Elevator 2 is 15 feet below ground level

C. Elevator 1 is 12 feet above ground level and Elevator 2 is 15 feet below ground level.

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
