Answer:
Step-by-step explanation: The area of the bedroom is
A=7yd^2
The total cost is the sum of the price rates times this area.
C=A•($21+$5)/yd^2
where C is total cost.
C=7yd^2•($21+$5)/yd^2
C=$182
Answer:
equivalent to 
Step-by-step explanation:
Given ratio,
It can be written as 
cancel common factor,
In math terms this means x divided by 3=3 so x so x means 9 so the answer is nine
<span>I got 2^(3/5) as the answer</span>
The length of each of the equal sides is become x = (3y-4) cm
According to the statement
we have given that the perimeter of the isosceles triangle and length of third side. and we have to find the length of same side of triangle.
So,
An isosceles triangle is a triangle that has two sides of equal length.
Let the equal sides of isosceles triangle be x cm each.
We know that the
Sum of sides of a triangle = perimeter
x+x+(3y-7) = 9y-15
2x = 9y-3y-15+7
After solving the equation it become
2x= 6y-8
x=(6y-8)/2
Now the length of equal sides is x=3y-4
So, The length of each of the equal sides is become x = (3y-4) cm
