Solve for y in the following equation.

Tju [1.3M]

Answer:

$y = \frac{z^2 - x}{2}$

Step-by-step explanation:

Given:

$\sqrt{x + 2y} = z$

Required:

Solve for y (make y the subject of the formula)

SOLUTION:

$\sqrt{x + 2y} = z$

Square both sides

$(\sqrt{x + 2y})^2 = z^2$

$x + 2y = z^2$

Subtract both sides by x

$2y = z^2 - x$

Divide both sides by 2

$y = \frac{z^2 - x}{2}$

5. Keisha makes $ 135 selling items at a concession stand. She sold an equal number of T-shirts and keychains. The T-shirt costs

exis [7]

Answer:

$108

Step-by-step explanation:

Let n be the cost of a keychain, then the cost of a T-Shirt would be 4n. We can use this to set up an equation...

4n+n=135

Combine like terms

5n=135

Divide both sides by 5

n=27

Now we need to find how much she made from selling T-Shirts...

4n=4(27)=$108
