Luden [163]

Answer:
Kevin made $800 in commissions last week.

Explanation:
Since we know that he only makes money in two ways, by base salary and commission, we know that added together they equal his whole pay.

Therefore we can set up the following equation and solve for his commission amount. 
Total Pay = Base Pay + Commissions.
1125 = 325 + Commissions.
800 = Comissions.

What is the value of x? Enter your answer in the box.

OverLord2011 [107]

5x + 10 10
---------- = -------
121 11

make the bottom have same common denominator

10/11 x (10/10) = 100/121

Get rid of the denominator (for both now have 121 as a base)

5x + 10 = 100

5x + 10 (-10) = 100 (-10)

5x = 90

5x/5 = 90/5

x = 18

x = 18 is your answer

hope this helps

Find the slope of the line that passes through the pair of points

professor190 [17]

$Slope= \frac{y_2-y_1}{x_2-x_1} = \frac{-\frac{9}{2} - (-1)}{-2- (-\frac{5}{3})}=\frac{ - \frac{9}{2} + 1}{-2 + \frac{5}{3}} \\= \frac{ - \frac{7}{2}}{ - \frac{1}{3}} \\= \frac{ - \frac{7}{2}\cdot6}{ - \frac{1}{3}\cdot6} \\=\frac{-21}{ -2} \\ =\boxed{\bf{ \frac{21}{2}}}$

So... none of your answers are correct. The correct answer is 21/2.
