denpristay [2]

x − 3y = 12
<span>2x + 6y = 60</span>

<span>x=12+3y</span>

<span>2(12+3y)+6y=60</span>

<span>24+6y+6y=60</span>

<span>24+12y=60</span>

<span>12y=60-24</span>

<span>12y=36</span>

<span>y=36/12</span>

<span>y=3</span>

<span>and since the only answer you have with y being 3 is 21,3 the answer is D.(21,3)</span>

Find the values of
astra-53 [7]

The values of AB, BC, CD and AD are the distance between their endpoints.

<em>The lengths cannot be determined.</em>

I've attached the required diagram.

The length of the segments cannot be calculated; so, I will give the steps to calculate the lengths.

  1. <em>Draw a straight through each endpoint</em>
  2. <em>Measure the length of straight using a ruler.</em>
  3. <em>Record each length</em>

<u>Approximate to the nearest eighth of an inch.</u>

To approximate to the nearest eighth of an inch means that, you approximate to the nearest 0.125

Assume the length of AB is:

AB = 4.51

<u>The eighths of an inch are: </u>

0.125, 0.250, 0.375, 0.500, 0.625, 0.750, 0.875, 1.000

<em>0.51 is between 0.500 and 0.625, but it is closer to 0.500.</em>

So, the approximated value would be

AB = 4.500

Assume BC is:

BC = 4.200

<em>0.200 is between 0.125 and 0.250, but it is closer to 0.125.</em>

So, the approximated value would be

BC = 4.250
