For this case we have the following system of equations:
To solve, we clear "x" from the second equation:
We substitute "x" in the first equation:
We clear the value of the variable "y":
We look for the value of the variable "x":
Thus, the solution of the system is given by:
Answer:
Option D
Answer:
The total area of both rooms and the aquarium is equal to 10,932 ft²
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
the length sides of Aquarium are
(83-32) x (72-52)-----> 51 ft x 20 ft
Area reptile room=(83*72)-area of aquarium----> 83*72-51*20---> 4,956 ft²
[ total area of both rooms]=2*4,956-----> 9,912 ft²
I'm assuming that the two areas are equal
Area of aquarium=51*20=1,020 ft²
therefore
the total area of both rooms and the aquarium is equal to
9,912 ft²+1,020 ft²=10,932 ft²
