Answer: Multiply
2 * 1 5/6
Convert 1 5/6 into an improper fraction:
2 * 11/5

<span>5(x-3)= 7x-2(x+)1
5x - 15 = 7x - 2x + 1
5x - 15 = 5x + 1
-5x -5x
- 15 = 1
NO SOLUTIONS because -15 is not equal to 1 </span>
Answer:
$ 2.167
<h3>
Step-by-step explanation:</h3>
Let the cost of a pencil be x and that of a pen be y.
A pen costs <u>twice</u> as much as a pencil.
==> cost of a pen = 2 × cost of a pencil
==> <u>y = 2x</u>
Their total cost is $6.50
==> x + y = $6.50
<em>since</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em>x</em><em>,</em><em> </em><em>substituting</em><em> </em><em>y</em><em> </em><em>for</em><em> </em><em>2</em><em>x</em>
==> x + 2x = 6.50
==> 3x = 6.50
<em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em>
==> x = 2.16
As per our assumption, x is the cost of one pencil.
Therefore, the cost of a pencil is <u>$2.16</u><u>7</u>
