A. 20. plug 20 in to both equations and they will be equal to eachother
Set up a system of equations
Let x=first salesperson's paycheck
y=second salesperson's paycheck
x= y-.15y
x+y= 1425
Solve by substituting x
(y-.15y)+y= 1425
1.85y= 1425
y= 770.27
Substitute 770.27 for y in order to solve for x
x= (770.27)-.15(770.27)
x= 770.27-115.54
x=654.73
So the first salesperson(x) has a paycheck of $654.73 and the second salesperson(y) has a paycheck of $770.27.
Hope this helps!
Answer:
117
Step-by-step explanation:
Sum of all angles of pentagon = 540
x + 86 + 140 + 138 + 59 = 540
x + 423 = 540
x = 540 - 423
x = 117
The side lengths are congruent, because the triangle is only being moved
