Answer: The table is proportional.
Step-by-step explanation: You would do 21/6 to get 3.5. Then 28/8 to get 3.5. After 35/10 to get 3.5. Finally 49/14 to get 3.5. If each answer (3.5) is the same than it is proportional.
4 hours = 4×60

240÷12
= 20 songs
the correct answer is 20 songs

Answer:
Step-by-step explanation:
<u>Expression on the board :</u>

<u>Expression by the student </u>:
<em><u> Expression 1 </u></em>:

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.
<em><u>Expression 2 :</u></em>
<em><u /></em>
<em><u /></em>
The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
