Answer:
Length C, B= 90 mi
Step-by-step explanation:
The small square in the corner in any shape always represent 90°
<em>Hope it helps!!</em>
81 * 1 / 27^y = 9 ^2y+1
81 * 1 / 9^3y/2 = 9 ^ 2y+1
9^3y/2 * 9 ^ (2y+1) = 81
9 ^ ( 3y/2 + 2y + 1) = 81 = 9^2
3y/2 + 2y + 1 = 2
7y/2 = 2 -1 = 1
7y = 2
y = 2/7 answer
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>
