Answer:

<em>22 person-hours of labor</em>

Step-by-step explanation:

<em>From the example given, we recall the following statement </em>

<em>Let  the number of person-hours of labor to break up a  driveway and clear away the rubble = be 14</em>

<em>Let the  number of  person-hours of labor to pour and smooth concrete for the new driveway be = 8</em>

<em>We can then sum up both of the activities, which is,</em>

<em>14 + 8 = 22, </em>

<em>Therefore,</em>

<em>To break up a driveway, clear away the rubble, pour the concrete, and smooth the concrete, it will take 22 number of  person-hours of labor to achieve that.</em>

For this case what you must do is add the number of hours to perform the different activities.
 We have then:
 14 person-hours of labor to break up to driveway and clear away the rubble.
 8 person-hours of labor to pour and smooth concrete for the new driveway.
 Adding both activities we have
 14 + 8 = 22
 answer
 it takes to break up to driveway, clear away the rubble, pour the concrete, and smooth the concrete about 22 person-hours of labor

Slope is defined as the change in y divided by the change in x between two points. Slope = y2 - y1/x2 - x1 -2 - 4/ -1 - (-4) -6/3 -2 Hope this helps!

Scholar #2 is correct. You take 15=-3m-18+5m-7 and combie like terms. Which will leave you with 15=2m-25. You will simplify from there, getting 20=m.
