Answer:
423
Step-by-step explanation:
623+223=846/2=423
The real answer is y=tan(x-pi)-1
F(X)=13 Just Plug 10 into the X in the equation
.25x+.10y=$10
.25 because that is the value of the quarter, times x the number or quarters you have and .10 because that is the value of the dime times y, the number of dimes you have.
