<em>Greetings from Brasil....</em>
According to the statement of the question, we have:
<h2>3X + 4 = 28</h2>
isolating X we get
X = 8
no. mike added the two fractions incorrectly by not changing them to common denominators.
the correct answer:
4/7 + 1/4 = ?
4/7 = 16/28 (multiply both the numerator and denominator by 4 to get the common denominator fraction)
1/4 = 7/28 (multiply both the numerator and denominator by 7 to get the common denominator fraction)
16/28 + 7/28 = 23/28 (only add the numerators!!)
mike covered <u>23/28 </u>of the distance from his home to the library. (always check to see if your answer can be simplified)
