Excercise 1:

No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.

p = parameter
w = width

w+2.75

p = 2w+2(w+2.75) = <span>4w</span>+<span>5.5 = 30

Answer to the last one:

w = 6.125</span>

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
