Y=1/2x+4 and 2y+4=x so substitute y into the second equation to get
2(1/2x + 4) =x
use the distributive property to get x + 8 = x. There is no solution to this equation because x + 8 cannot equal x, and because of this you cannot solve the rest of it so there is no solution.
5 times 1 + 1 times 1/10 + 5 times 1/100 + 3 times 1/1000
Area divided by length= width
x^3+12x^2+47x+60 ÷ x+5=w
Original price = $40
Sale price =$22
Reduction = $18
% Reduction
Reduction/Original price × 100%
18/40 × 100% = 45%
Answer = 45%
