<h2>
<em><u>THE CORRECT ANSWER IS B- 73 FEET</u></em></h2>
<em>The given condition in question will form a right angle triangle </em>
<em>and the length of sides of triangle are given 55ft, 48ft and missing one.</em>
<em>Now using pythagoras theorem</em><em>,55²+48²= x²</em>
<em>x² = 3025 + 2304</em>
<em>x² = 5329</em>
<em>Taking square root of 5329 will give 73 ft!</em>
Answer:
number a is correct answer
Answer:
8x - 28y
Step-by-step explanation:
-2(-1x + 5y) + 3(2x - 6y)
2x - 10y + 6x - 18y
collect like terms
2x + 6x - 10y - 18y
8x - 28y
Answer:
108 books.
Step-by-step explanation:
Let the number of magazines = m
Let the number of books = b
<u>Given the following data;</u>
Total number of m & b = 162
<em>Translating the word problem into an algebraic equation, we have;</em>
......equation 1
......equation 2
<em>Substituting equation "1" into equation "2" we have;</em>
m = 54
Now to find the number of books;

Substituting the value of "m" into the equation, we have;
<em>b = 108</em>
<em>Therefore, the total number of books in the library is 108 books. </em>
