(5/8)+(2/5)=
so you need a common den so in this case its 40
so we multiply to get 40 like
(5/5)(5/8)+ (2/5)(8/8)=
25/40 + 16/ 40 = 41/40
4(5x-20)=-20
20x-80=-20
20x=60
x=3
"of" means to multiply.
20% * 60
= 0.2 * 60 (since % means divide by 100)
= 12
-24.3 feet
-22.55-19.5 is -42.05
-42.05+ 17.75 is -24.3

Answer:
15/22 peso/m^2 ≈ 0.68182 peso/m^2
Step-by-step explanation:
The area is the product of the dimensions. 1 km = 1000 m.
A = (550 m)(550·1000 m) = 302,500,000 m^2
The price per square meter is ...
206,250,000/302,500,000 peso/m^2
= 15/22 peso/m^2 ≈ 0.68182 peso/m^2
