Solve. To solve this equation, you must change the divide sign into a multiplication sign.

To do so, change it into a multiplication sign, and flip the second fraction

(5/12)/(2/11) = 5/12 x 11/2

Multiply across

5/12 x 11/2 = 55/24

55/24, or 4 7/12

hope this helps

Answer:

A. n = 5

Step-by-step explanation:

S = n² + n

When S = 30:

n² + n = 30

Subtract 30 from both sides: n² + n - 30 = 0

Factorize: (n - 5)(n + 6) = 0

Therefore n = 5 or -6

As n > 2, then n = 5 only
