To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.

2/10 = x/5

Now, we can use cross products to simplify this proportion.  Cross products sets the products of the numerator and denominator of separate fractions equal to one another.  It results in the equation:

(5)(2) = (10)(x)

Let's multiply out these numbers to further simplify the equation.

10 = 10x 

Finally, we have to divide both sides by 10, to get our variable x alone

x = 1

Therefore, 2 tenths is equal to 1 fifth.

Solve the equation.<br> 8 -(x + 5) = 5x - 3
Mandarinka [93]

Answer:

x = 1

Step-by-step explanation:

8 -(x+5) = 5x - 3

-(x+5)  --->   -1 (x +5) = -x - 5

8 - x - 5 = 5x -3            8 - 5 = 3

-x + 3 = 5x - 3

+x         +x

3 = 6x - 3

+3       +3

6 = 6x

/6   /6

<u>x = 1</u>

What is 2x+8y=12 in slope intercept form <br>as well as x-2y=0 in slope intercept form 
earnstyle [38]
the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\ 2x+8y=12 \ \ |-2x \\ \\8y=-2x+12\ \ /:8\\ \\y=-\frac{2}{8}x+\frac{12}{8}

y=-\frac{1}{4}x+\frac{3}{4}\\ \\ m=-\frac{1}{4}



x-2y=0 \ \ | -x \\ \\-2y=-x \ \ /:(-2)\\ \\y=\frac{1}{2}x \\ \\ m= \frac{1}{2}
