Answer:

N is -6

Step-by-step explanation:

1. You could cross multiply the n/n-3 and 2/3

2. To cross multiply , you would multiply n times 3 and n-3 times 2

3. After cross multiplying you would get the equation of 3n=2n-6

4. You subtract 2n on both sides of the equal side, making the equation 1n=-6

5. 1n is N , and N is equal to -6, which is the answer

Answer:

4\frac{2}{3}

Step-by-step explanation:

This is a recurring decimal.

Let x = 4.666666...                 ⇒ (1)

  10x = 46.66666...                     ⇒ (2)

Subtract equation (1) from equation (2)

    10x = 46.66666..

   -<u>  x = 4.666666...  </u>

    <u>  9x = 42.0000.....</u>

<u />

9x = 42

  x =  42/9

      = 14/3

       =4\frac{2}{3}

Which similarity postulate or theorem can be used to verify that the two triangles shown below are similar?
Vesnalui [34]

Answer:

C. Similarity cannot be determined

Step-by-step explanation:

Two triangles are considered similar when all three angles are equal and also when the ratio of their corresponding side lengths are equal.

Since we only know the angles of the two triangles given and we are not given the side lengths to determine if their corresponding ratio is the same, we therefore cannot determine if the two triangles are similar in anyway.
