  • Answer:

<em>1. x = - 7/3 = - 2  1/3</em>

<em>2. x = -2</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em />

<em>3x + 12 = - 6x - 9</em>

<em>3x + 6x = - 12 - 9</em>

<em>9x = - 21</em>

<em>x = - 21⁽³/9</em>

<em>x = - 7/3</em>

<em>x = - 2  1/3</em>

<em />

<em>12x + 20 = 2x</em>

<em>12x - 2x = - 20</em>

<em>10x = - 20</em>

<em>x = - 20/10</em>

<em>x = - 2</em>

<em />

<em>Good luck !</em>

Kimberly rides her bicycle from her home to school at an average rate of 12 mph if it takes her 20 minutes to get to school how
Thepotemich [5.8K]

Kimberly's home is 6.6 miles away from her school.

Step-by-step explanation:

The formula for speed will be used to calculate distance between home and school of Kimberly.

The formula for speed is:

s=\frac{d}{t}

Here

d is distance

s is speed and

t is time

Given:

Speed=s=12\ mph\\Time=t=20\ min\\\\We\ have\ to\ convert\ the\ time\ into\ hours\ for\ same\ unit\\t=20\ min = \frac{20}{60} = 0.33\ hour\\Now,\\20=\frac{d}{0.33}\\20*0.33=d\\d=6.6\ miles

Kimberly's home is 6.6 miles away from her school.
