<u><em>Given:</em></u>
<em>Samantha needs to purchase 7 notebooks at </em>
<em>$2.99 each and 5 pencils at $0.79 each. </em>
<u><em>To Find:</em></u>
<em>About how much will Samantha spend before sales tax?</em>
<u><em>Solution:</em></u>
<em>All we have to do is multiply and then add. </em>
<em>Starting with NoteBook;</em>
<em>Since each notebook cost - $2.99</em>
<em>Then 7 Notebook..</em>
<em>7 × $2.99</em>
<em>= $20.93</em>
<em>Now with Pencil;</em>
<em>Since each pencil cost - $0.79</em>
<em>Then 5 Pencil..</em>
<em>5 × 0.79</em>
<em>= $3.95</em>
<em>As a result, we add both together</em>
<em>$20.93 + $3.95</em>
<em>=$24.88</em>

Answer:

Step-by-step explanation:
Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that 180 = 4R - 8 Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.
-3/4x+y = -5/2 is the answer.
