Answer:

$\huge\boxed{x=-\dfrac{7}{2}=-3.5}$

Step-by-step explanation:

$3(-10x-3)+6x=75\qquad/\text{use the distributive property}\\\\(3)(-10x)+(3)(-3)+6x=75\\\\-30x-9+6x=75\qquad/\text{add 9 to both sides} \\\\(-30x+6x)-9+9=75+9\\\\-24x=84\qquad/\text{divide both sides by (-24)}\\\dfrac{-24x}{-24}=\dfrac{84}{-24}\\\\x=-\dfrac{84:12}{24:12}\\\\x=-\dfrac{7}{2}$

A long-distance athlete can run 1212 kilometer in 3 minutes. How many kilometers can he run in an hour?

nadezda [96]

Assuming he runs the same rate for an hour, 24240 kilometers in an hour.

Divide 1212 by 3 and you get 404 kilometers in one minute.

404km times 60min equals 24240km.
