Vika [28.1K]

Answer:

n < 9

Edgar Anderson earns $200 a week plus a 15% commission on all sales over $1,000. If Mr. Anderson's sales for one week are $2,500
nignag [31]
<span>Find the gross pay of Mr. Anderson in a week.
He earns 200 dollars a week + 15% commission on over 1000 dollars sales.
In a week he earned 2500 dollars.
=> Pls, take note, that he can only get a 15% commission for over 1000 dollars sales he get.
=> 2 500 dollars – 1 000 dollars
=> 1 500 dollars, now in 1500 dollars get the 15% commission
=> 1 500 x .15
=> 225 + 200 (his original earnings)
=> 425 dollars.</span><span>

Use the relationship between the angles in the figure to answer the question.
Anuta_ua [19.1K]

Answer:

37+x+53 = 180

x=90

Step-by-step explanation:

To find x, we need to use the fact that a straight line equals 180 degrees.

37+x+53 = 180

Combining like terms

90+x = 180

Subtract 90 from each side

90-90+x = 180-90

x = 90
