Which equation using x to represent time best represents the floor number of an elevator descending at a steady rate?

zepelin [54]

C. You'd be starting at a higher floor (positive number) and descending floors (negative number per x). If you assume x is time it's a little more logical and visual.

3(-0.4n-0.7)=-3.2n-2.58

svlad2 [7]

Answer:

$n=-0.24$

Step-by-step explanation:

$3\left(-0.4n-0.7\right)=-3.2n-2.58$

Use distributive property.

$-1.2n-2.1=-3.2n-2.58$

$-1.2n-2.1+2.1=-3.2n-2.58+2.1$

$-1.2n=-3.2n-0.48$

$-1.2n+3.2n=-3.2n-0.48+3.2n$

$2n=-0.48$

$\frac{2n}{2}=\frac{-0.48}{2}$

$n=-0.24$
