NikAS [45]

Answer:

<em>Colin spends 1/8 of an hour practicing each song</em>

Step-by-step explanation:

Colin's piano lesson is 3/4 of an hour, long.

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

\displaystyle \frac{\frac{3}{4}}{6}=\frac{3}{24}=\frac{1}{8}

Colin spends 1/8 of an hour practicing each song

X+3y=14<br> y=3x-14<br> Solving systems using substitution <br> How do i do this?
Free_Kalibri [48]
X + 3y = 14
x + 3(3x - 14) = 14
x + 9x - 42 = 14
10x - 42 = 14
<u>      + 42 + 42</u>
       <u>10x</u> = <u>56</u>
        10     10
           x = 5.6
5.6 + 3y = 14
<u>- 5.6         - 5.6</u>
         <u>3y</u> = <u>8.4</u>
          3       3
           y = 2.7
     (x, y) = (2.7, 5.6)
