Answer:
31.1
Step-by-step explanation:
Answer:
x = 348
Step-by-step explanation:
From the given we can tell it a supplementary angle.
<u>Don't know what supplementary angle is?</u>
<em>Supplementary angle are angles that :</em>
<em>Equal 180 °</em>
<em />
<u><em>Solve: </em></u>
<em>Since,</em>
<em>∠ABD is (0.18x+54)° </em>
<em>∠CBD is (0.07x+39)°</em>
<em />
<em>Thus,</em>
<em>(0.18x+54) + 0.07x + 39 = 180</em>
<em>Group likes terms:</em>
<em>0.25x + 54 + 39 = 180</em>
<em>0.25 + 93 = 180</em>
<em>Subtract 93 from both sides</em>
<em>0.25x = 87</em>
<em>x = 348</em>
<em />
<em>Check Answer:</em>
<em>0.18(348) + 54 + 0.07(348) + 39 </em>
<em>= 180</em>

<h3>Write the sum of the numbers as the product of their GCF and another sum</h3>
Answer 23: 56 + 64 = 8 (7 + 8)
Answer 24: 48 + 14 = 2 (24 + 7)
Answer 25: 30 + 54 = 6 (5 + 9)
Answer 26: 24 + 40 = 8 (3 + 5)
Answer 27: 55 + 66 = 11 (5 + 6)
Answer 28: 49 + 63 = 7 (7 + 9)
Answer 29: 40 + 25 = 5 (8 + 5)
Answer 30: 63 + 15 = 3 (21 + 5)
