Answer:
No.
Step-by-step explanation:
20+25+15 = 60
A right is 90°. Therefore, 20, 25, and 15 do not make a right angle.
Answer:
x = 1.5
Step-by-step explanation:
5x - 5 - 3x + 2 = 0
Combine like terms
2x - 3 = 0
Isolate variable x
Add 3 to both sides
2x = 3
Divide both sides by 2
x = 3 ÷ 2
x = 1.5
You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.
If the salesman sells a car for $<em>a</em> and gets <em>b</em>% of the sale price as commission, then what you need to do is divide the <em>a</em> by 100, then multiply it by <em>b</em> to find out <em>b</em>% of <em>a</em>. This will be the commission that he will earn.
<em>a </em>/ 100 x <em>b</em> = commission earned in $
Edit
<em>You've now supplied me with the $ and %, let me explain it again.</em>
To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.
8,100 / 100 = 81
81 x 9 = $729 commission earned.
