The equation for the expression is M-4=A Because it says Amy is 4 years younger than Marty
The total amount of his commission for these vehicles is $ 1686
<em><u>Solution:</u></em>
Given that,
Miles earns a 6% commission on each vehicle he sells
Therefore,
Commission rate = 6 %
Today he sold a truck for $18,500 and a car for $9,600
Therefore,
Commission amount = 6 % of (18500 + 9600)
Commission amount = 6 % of 28100
Calculate the above equation

Thus the total amount of his commission for these vehicles is $ 1686

Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
