Answer:

n=7

Step-by-step explanation:

First, move 9 to the other side of the equation.

4n=37-9

Then, simplify the equation.

4n=28

Finally, find the value of n by dividing both sides by 4.

4n/4= n 28/4=7

Thus, n=7

$4n + 9 = 37\\4n = 37 - 9\\4n = 28\\n = \frac{28}{4}\\n = 7$

Which expressions are equivalent to 1 divided m/6? Check all that apply

jenyasd209 [6]

Answer:

option A, option C, option D

Step-by-step explanation:

a) 1 ÷ m/6

can be written as

$\frac{1}{1}$ ÷ $\frac{m}{6}$

b) sides in (m/6) will change if both has to multiply

c) 1 ÷ m/6

can be written as

1 * 6/m

1( $\frac{6}{m}$ ) and wont make change to answer. so matches with the question.

1 ÷ m/6

1 * 6/m

1 * 6 * $\frac{1}{m}$

6 * $\frac{1}{m}$

6 ÷ m ..therefore true

1 ÷ m/6

1 * 6/m

6/m ....does not match or can be converted to the following so wrong

Therefore A, C, D are correct and B and E is wrong.

\frac{1}{5}k-9=\frac{3}{5}k-7

Oksi-84 [34.3K]

let start by multiplying both sides by the LCD of all denominators, in this case that'd be 5, to do away with the denominators.

$\bf \cfrac{1}{5}k-9=\cfrac{3}{5}k-7\implies \stackrel{\textit{multiplying by }\stackrel{LCD}{5}}{5\left( \cfrac{1}{5}k-9 \right)=5\left( \cfrac{3}{5}k-7 \right)}\implies k-45=3k-35 \\\\\\ -45=2k-35\implies -10=2k\implies \cfrac{-10}{2}=k\implies -5=k$
