Answer:
<em>here </em><em> </em><em>,</em>
<em>8</em><em>1</em><em>=</em><em>3</em><em>x</em>
<em>or </em><em>,</em><em> </em><em>8</em><em>1</em><em>/</em><em>3</em><em>=</em><em>x</em>
<em>or,</em><em>2</em><em>7</em><em>=</em><em>x</em>
<em>hence </em><em>,</em><em>the </em><em>value </em><em>of </em><em>x=</em><em>2</em><em>7</em>
1 hour and 10 minutes = 70 total minutes
The aerobics class is 20 minutes and then since the yoga class is 30 minutes longer it will then be 50 minutes.
20 minutes aerobic+50 minutes yoga= 70 total minutes

<h2>Hello!</h2>
The answer is:
The second option, Denver received 21.3 inches of snow during the period from 1888 to 1889.
<h2>Why?</h2>
To know how many inches of snow did Denver receive, we need to sum each the number of inches received per year from 1888 to 1889.
So, from the graph, we have:
For Nov '88, 3 inches.
For Dec '88, 0.8 inches.
For Jan '89, 5.5 inches.
For Feb '89, 8.4 inches.
For Mar '89, 3.6 inches.
Now, adding the number of inches for each month/year, we have:

Hence, we have that Denver received a total of 21.3 inches for the 1888-1889 year period.
Have a nice day!
