Answer:

-12x-15-8x=85 (first combine like terms)

-20x-15=85 (now add 15 to 85, to get x by itself)

-20x=100 (now divide 100 by negative 20)

x=-5

Lenny works at Lexus selling cars. His salary is $40,000 a year plus commission. He gets 1.25% commission on the cars he sells.
max2010maxim [7]

Answer:

$71, 250

Step-by-step explanation:

Given that:

Fixed salary of Lenny = $40,000

Commission on the cars sold by Lenny = 1.25%

Cost of each Lexus car = $50,000

Total worth of which cars are sold by Lenny = $2,500,000

To find:

Lenny's total income after a year?

Solution:

Lenny's salary consists of two parts i.e. Fixed salary and the variable part as per the commission depending upon the sales done by Lenny.

Fixed salary = $40,000

Commission earned = 1.25% of $2,500,000

\Rightarrow \dfrac{1.25}{100}\times 2500000\\\Rightarrow \$31,250

Therefore, Lenny's total salary after a year = $40,000 + $31,250 = <em>$71, 250</em>

What is the slope of all lines perpendicular to the line y=(2/3)x+7
Alexandra [31]

Answer:

The slope is -3/2

Step-by-step explanation:

<u>A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal. </u>

Example:  Find the line perpendicular to y = 3x

First, you flip the sign which makes 3 into -3

Next, you make the reciprocal which makes -3 into <u>-1/3 </u>

Problem:  Find the line perpendicular to y = (2/3)x + 7

First, you flip the sign which makes 2/3 into -2/3

Next, you make the reciprocal which makes -2/3 into <u>-3/2</u>

Answer:  The slope is -3/2
