The answer is the number that 'x' must be in order for
that equation to be a true statement. Here's one way
to find out what the number is:
x + 36 = 4x
Subtract 'x' from each side: 36 = 3x
Divide each side by 3 : 12 = x
Answer:
see the explanation
Step-by-step explanation:
we know that
If the triangular piece of sheet metal is a right triangle, then the side lengths must satisfy the Pythagorean Theorem
so
where
c is the hypotenuse (the greater side)
a and b are the legs of triangle
we have
substitute
----> is true
so
The side lengths satisfy the Pythagorean Theorem
therefore
The triangular piece of sheet metal is a right triangle

It's so dark! There are some words I can't see.
Answer:
x = 8/3
y = 7/3
Step-by-step explanation:
In a parallelogram the diagonals bisect each other.
So 2x = y + 3
x + y = 5
Then you set them up to do combination/elimination to solve for the two variables.
2x-y = 3
Then you add the two equations together
3x = 8
Solve for x
x = 8/3
Then solve for y by plugging it into a equation
x + y = 5
8/3 + y = 5
8/3 - 5 = -y
8/3 - 15/3 = -y
-7/3 = -y
y = 7/3
