Solve for m d=n+7m Thank you

Answer:  \displaystyle m = \frac{d-n}{7}

This is the same as writing m = (d-n)/7

The parenthesis are essential for the second format because it tells us to divide all of (d-n) over 7, and not just n over 7.

============================================================

Explanation:

Here is one way to solve for m. I'll go over each step in the next section below.

d = n+7m\\\\n+7m = d\\\\7m = d-n\\\\m = \frac{d-n}{7}

The idea is to get the variable m by itself.

Think of n+7m as 7m+n since we can add in any order. Then undo the "plus n" portion by subtracting n from both sides (step 3).

In the 4th step, I divided both sides by 7 to undo the multiplication that is going on with 7m aka 7*m

In general we follow PEMDAS backwards to undo each operation done to the variable we're solving for. Let me know if you have any questions about what I mean.

TEA [102]

Answer:

2.\:\frac{41}{9}

Step-by-step explanation:

Recall that \frac{x}{9}=\lfloor \frac{x}{9} \rfloor + 0.\overline{[x\:\mod9]}.

Therefore, 4.\bar{5}=\frac{4\cdot 9 + 5}{9}=\fbox{$2)\:\frac{41}{9}$}.

Five over seven plus blank over six equals fifty one over forty two
NISA [10]

Answer:

The blank is 3

Step-by-step explanation:

1 - Give the blank a variable

x = our blank

2 - Write it out

\frac{5}{7} + \frac{x}{6} = \frac{51}{42}

3 - Get the denominators equal

\frac{5}{7}(\frac{6}{6}) +\frac{x}{6}(\frac{7}{7}) = \frac{51}{42} \\\frac{30}{42}+\frac{7x}{42} = \frac{51}{42}

4 - Simplify

\frac{30+7x}{42} = \frac{51}{42} \\ \frac{30+7x}{42} = \frac{51}{42}

5 - Solve for the numerators

30+7x = 51

-30         -30

      7x = 21

        x = 3
