You paint one third of a wall and one for seven hours at that rate how long will it take you to paint one wall

We can put this word problem into an equation.

1/3x = 7

Now we just have to solve for x. To find x we need to multiply by three on both sides.

1/3x = 7
*3 *3
-------------
x = 21

So it will take 21 hours to paint one wall.

Find the unknown side length x.

Ganezh [65]

Answer:

x = $\sqrt{65}$

Step-by-step explanation:

The altitude of the triangle must equal 4 because it is a right triangle with another leg of 3 and a hypotenuse of 5 (reason is due to the pythagorean theorem)

Therefore, the triangle on the right has legs of 4 and 7 and, again, use the phythagorean theorem to find 'x' (the hypotenuse)

$4^{2}$ + $7^{2}$ = $x^{2}$
