So thi sis really simple since you have an equal sign so



(n/3)-(5n/6)=1/3
to subtract fractions, make the bottom number the same
n/3 times 2/2=2n/6
(2n/6)-(5n/6) or (2n-5n)/6 so
-3n/6=1/3
multiply both sides by 6
-3n=6/3=2
-3n=2
divide both sides by 3
-n=2/3
mmultiply boht by -1
n=-2/3
tada
n=-2/3

\frac { n }{ 3 } -\frac { 5n }{ 6 } =\frac { 1 }{ 3 } \\ \\ n\left( \frac { 1 }{ 3 } -\frac { 5 }{ 6 }  \right) =\frac { 1 }{ 3 } \\ \\ n\left( \frac { 2 }{ 6 } -\frac { 5 }{ 6 }  \right) =\frac { 1 }{ 3 }

\\ \\ -\frac { 3 }{ 6 } n=\frac { 1 }{ 3 } \\ \\ -\frac { 1 }{ 2 } n=\frac { 1 }{ 3 } \\ \\ \frac { 1 }{ 2 } n=-\frac { 1 }{ 3 } \\ \\ 2\cdot \frac { 1 }{ 2 } n=-\frac { 1 }{ 3 } \cdot 2\\ \\ n=-\frac { 2 }{ 3 }

IS 71 OVER 20 SIMPLEST FORM?IF NOT WHATS THE ANSWER?
dem82 [27]

71/20 is not in simplest form because you need to change it into a mixed number by dividing 71 and 20 and putting the remainder over 20.

Is (2, -4) a solution to the inequality 2x - 3y < 15? Yes or No
miss Akunina [59]

Answer:

No.

Step-by-step explanation:

We substitute the values x = 2 and y = -4 into the inequality.

Left side = 2(2) - 3(-4) = 4 + 12

= 16

Now the right side is 15 so we get 16 < 15 which is incorrect.

So (2, -4) is not a solution.

The equation that can be used to determine the measure of ∠A is tanA = 9.4/6.7. The correct option is A. tanA=9.4/6.7

<h3>Trigonometry</h3>

From the question, we are to determine which of the given equations can be used to determine the measure of ∠A

In the diagram,

If ∠A is the included angle

Then,

Using<em> SOH CAH TOA</em>

Opposite = 9.4

Adjacent = 6.7

Thus,

tanA = 9.4/6.7

Hence, the equation that can be used to determine the measure of ∠A is tanA = 9.4/6.7. The correct option is A. tanA=9.4/6.7
