Answer:
-5y + 3x (or) 3x - 5y
Step-by-step explanation:
-8y-(x-4x)+3y
Solve the problem in the parentheses first. (x-4x)
-8y-(-3x)+3y
The problem within the parentheses is as simplified as we are going to get it. Now we can simplify the y values. (-8y + 3y)
-(-3x) -8y+3y
-(-3x) - 5y
Get our x value out of the parentheses now. -(-3x)
-(-3x) = +3x (two negatives makes a positive)
This leaves us with our simplified equation.
3x - 5y
or
-5y +3x
When you minus the 23.75 from 2000 you get 1976.25 and then divide that amount by 8 to get $247.03 per person.
Cotangent of angle A=base/height=24/10=12/5
cotangent of B=10/24=5/12
