Simplify\;-5x-6x \ \textgreater \  \mathrm{Add\:similar\:elements:}\:-5x-6x=-11x

Simplify\;8-8n-n \ \textgreater \  \mathrm{Add\:similar\:elements:}\:-8n-n=-9n
8 - 9n

-11x\ \textless \ 8-9n

\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)} \ \textgreater \  11x\ \textgreater \ -8+9n

\mathrm{Divide\:both\:sides\:by\:}11 \ \textgreater \  \frac{11x}{11}\ \textgreater \ -\frac{8}{11}+\frac{9n}{11}

Simplify \ \textgreater \  x\ \textgreater \ \frac{-8+9n}{11}

Papessa [141]

Answer: 75 minutes per hour.

Step-by-step explanation:

From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.

The rate per hour will then be:

= 15 ÷ 1/5

= 15 × 5
