Then
The reciprocal of 
is
I would say Korey because let’s say you have a rectangle and two sides are 2 and the other two sides are 5. Well if you add 5 + 2 which equals 7 times 2 equals 14, you get the same answer as you would if you added everything
Solving the system of equations we get 
and 
Step-by-step explanation:
We need to find the solution to the system of equations.
Solving the given equations and finding the values of x and y
Let:
Putting value of y from eq(2) into eq(1)
So, value of x is:
Putting value of x in eq(2) to find value of y
So, value of y is:

Answer:
9/16
Step-by-step explanation:
After the first exchange the amount in dollars is ...
£320 × $1.25/£1 = $400
After the spending, the amount in dollars is ...
$400 -100 = $300
After the second exchange, the amount in pounds is ...
$300 × £0.60/$1 = £180
This amount is 180/320 = 9/16 of the original amount.
Answer:
The answer to your question is: cost = $4000
Step-by-step explanation:
Data
Volume = 8000 ft³
cost = $10 / square foot
Process
It's a cube then we find the length of one side
Volume = l³ = 8000
l = ∛8000
I = 20 ft
Now, calculate the area of the floor,
Area = l x l
= 20 x 20
= 400
Finally, find the cost of the floor
cost = area x price
cost = 400 x 10
= $4000
