What is the multiplication problem that means the same thing as the division problem 1/9 divided by 12?
lianna [129]

<em>/Hello!</em>

<u><em>See below</em></u>

<em>We need to find x. X being the answer to 1/9 divided by 12.</em>

<em>1/9÷12=1/108. </em>

  • <em>=1×1/9×12</em>
  • <em>=11/08</em>
  • <em>=1/108</em>

<em>Now that we know what "x" equals, we can divide the others.</em>

<em>1/9x12=1 and  3/9 ------simplifed is------1 and 1/3</em>

<em>Convert any mixed numbers to fractions</em>

<em>.</em>

<em>Then your initial equation becomes:</em>

<em>1/9×12/1</em>

<em>Applying the fractions formula for multiplication,</em>

<em>=1×12/9×1</em>

<em>=12/9</em>

<em>Simplifying 12/9, the answer is</em>

<em>=1 and 1/3</em>

This is not correct.

1/9×1/12

Applying the fractions formula for multiplication,

=1×1/9×1/2

=1/108

This is correct.

Therefore, your answer is B. 1/9 x 1/12

Find the lowest common denominator (LCD) of<br> these fractions.<br> 3<br> 5<br> 8x<br> 18x
padilas [110]

Answer:

72x

Step-by-step explanation:

8x = 2 * 2 * 2 * x   = 2³ * x

18x = 2 * 3 * 3 * x = 2 * 3² * x

LCD = 2³ * 3² * x = 8 * 9 * x = 72x

Find the equation (in slope-intercept form) of the line passing through the points with the given coordinates.
Dmitrij [34]

Answer:

<h2>y = -2x + 1</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (1, -1) and (2, -3).

Substitute:

m=\dfrac{-3-(-1)}{2-1}=\dfrac{-2}{1}=-2

Put it and the coordinates of the point (1, -1) to the equation of a line:

-1=-2(1)+b

-1=-2+b          <em>add 2 to both sides</em>

1=b\to b=1

Finally:

y=-2x+1
