Answer:

A

Step-by-step explanation:

10/3x-3=7/x+15

Multiplying each term by 3x

3x(10/3x-3) = 3x(7/x+15)

10 - 9x = 21 + 45x which is a linear equation

Answer:

$900

Step-by-step explanation:

Use the formula for simple interest:  i = p r t, where i is the interest earned, p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.

Here, i = $27 = p(0.015)(2), or

               $27 = 0.03p

Dividing both sides by 0.03, we get:

p = $27 / 0.03 = $900

The principal, in this situation, was $900.
