Answer:
6 is your answer.
Step-by-step explanation:
There are fifty two weeks in the year.
To find how much commission she earns in a year, multiply her weekly commission by the number of weeks per year.
274*52= 14248
To find how much money is taken from taxes, multiply the amount of money she is taxed weekly by the number of weeks in a year.
68*52= 3536
Now, simply add the amount of money she made in the year with her bonus (which I'm assuming is a one time bonus for being hired) and subtract the amount of money she is taxed.
14248+550-3536= 11262
Mrs. Sanchez earns $11262 a year.

Substitute the values. 
Follow PEMDAS and multiply and divide first. 

Continue following PEMDAS and subtract. 
The formula for slope is: m = (y2 - y1) / (x2 - x1) ---> m = (b - b) / (-a - a) = 0/(-2a) = 0
The formula for volume is V=lhw, or length times height times weight. To find the length, you divide the volume by the height and width.
In this case, divide 3,060 first by 12, the height, then by 15, the width.
3,060/12=255
255/15=17
The length is 17.
