Answer:
h = r
Step-by-step explanation:
x = (r-h)/y
h + x y = r
x = r/y - h/y
r = h
y ≠ 0
Answer:
Given: 
Distributive Property tells us that we multiply each term inside the parentheses with the term outside of the parentheses.

Using distributive property on expression 6(y-2) to solve the further expression as:

Simplify:

Subtract the number 12 from 15 we get 3;
therefore, the expression become:

Subtraction property of equality tells us that subtract the same number from both sides of an equation.
Now, subtract 3 from both the sides we get;

Simplify:

Now, divide by 6 on both the sides we get;

On simplify we get;
y =3 Hence Proved!
Answer:
b=2b-53 : b=53. Then SU=53
Step-by-step explanation:
Solution
b=2b-53 : b=53
Steps
If QU=b and SU=2b-53
That mean b=2b-53 because QU=SU
Substract 2b from both sides
b-2b=éb-53-2b
Simplify
-b=-53
Divide both sides by -1
-b/-1=-53/-1
Simplify
B=53
NOTE :
Theorem 1: In a parallelogram, the opposite sides are of equal length. Theorem 2: If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram. Theorem 3: A quadrilateral is a parallelogram if and only if the diagonals bisect each other
First subtract 12 from both sides, then subtract 2x from both sides, multiply both sides by -1, then divide by 4.
x > 3.5
