Chris is incorrect. To check the answer, replace m with 8 and simplify the left side. So m/6 turns into 8/6 which converts to the decimal value 1.333 (use a calculator)
Therefore the original equation m/6 = 48 becomes 1.333 = 48 after you plug in m = 8 and simplify fully. The two sides of 1.333 = 48 are not the same, so m = 8 is not the solution.
--------------------
The solution is actually 288 and we can prove it so like this
m/6 = 48
288/6 = 48 .... replace m with 288
48 = 48 .... use a calculator to compute 288/6
So the solution m = 288 is confirmed
------------------
How did I get this answer? By multiplying both sides by 6
m/6 = 48
6*(m/6) = 6*48 ..... multiply both sides by 6
m = 288
So Chris mistakenly divided both sides by 6, which explains how he got 48/6 = 8 as the solution. Instead he should have multiplied both sides by 6. This is to undo the operation "divide by 6" that is being applied to m in the original equation.
Answer:
Step-by-step explanation:
Consider the quadratic equation, we have
Dividing the equation by a, we get
Put 
on the other side,
Add 
on both the sides,
completing the square, we have
Now, solving for x,
Multiply right side by 
,
which is the required quadratic formula.
8 minutes is 480 seconds.
So if you divide 480 by 25 you get 19 with a remainder of 5/25. You can only play 19 complete commercials in 8 minutes if they are 25 seconds long.
