He multiplied rather than dividing.

\mathrm{Divide\:both\:sides\:by\:}7 \ \textgreater \  \frac{7m}{7}=\frac{56}{7} \ \textgreater \  Simplify \ \textgreater \ m = 8

Hope this helps!

Answer: Multiplyng both sides by 7 instead of dividing both sides by 7.

Step-by-step explanation:

Hi, by analyzing Arjun’s work, the mistake that he made was multiplying by 7 both sides instead of dividing both sides by seven.  

The correct way is:

7m = 56

Dividing each both sides by 7  

7m/7 = 56/7

m = 8

The real value of m is 8, not 392.

Feel free to ask for more if needed or if you did not understand something.

Temka [501]

Answer:

35,136 ml

Step-by-step explanation:

The tank holds 55,000ml. Mr. Clark poured some gas into 3 container, and at the end there the tank had 19,864. To find how much gas was poured out of the tank it is the same as asking how much gas he poured in the 3 containers, all together. We have to find the difference, subtraction:

55,000 - 19,864 = 35,136ml were poured in the 3 containers or amount of gas poured out of the tank.

Form the union for the following sets m={} n={6,7,8,9,10}
Levart [38]

Answer:

M\cup N={6,7,8,9,10}.

Step-by-step explanation:

We have an empty set: M={} and the set N={6,7,8,9,10}.

The union of these two sets are elements in M or N or both.

Since the M is a null set, M\cup N=N

Therefore: M\cup N={6,7,8,9,10}.

The union for the given sets is {6,7,8,9,10}.
