TRUE! Good luck! I hope that helps
Answer:
Step-by-step explanation:
We need to find the solution to the following system of equations:
and
By plugging the value of 'y' into the first equation we have that:
⇒
Solving for 'x' we have:
So, the solution to the system of equation is: (37.5, -30)
Multiply both of the fractions so they both have the same denominator then add the
fractions together
Answer:
x=1 meter
Step-by-step explanation:
step 1
Find the area of the rectangular pool
we have
substitute
step 2
Find the area of rectangular pool including the area of the walkway
Let
x ----> the width of the walkway
we have
substitute
step 3
Find the area of the walkway
To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway
so
step 4
Find the value of x if the area of the walkway equal the area of the pool
so
Solve the quadratic equation by graphing
The solution is x=1 meter
see the attached figure
