Answer
When y = 9 and z = 6, the expression 9y - 10z becomes:
9(9) - 10(6) = 81 - 60 = 21.

Answer
To evaluate the expression, we first need to simplify the fraction: 5/27.
Next, we add the fraction 1/3 to 5/27.
To find a common denominator, we multiply the denominator of 1/3 by the denominator of 5/27, which is 3 * 27 = 81.
Now, we have:
1/3 + (5/27 * 3/3) = 1/3 + 15/81
To combine the fractions, we need to find a common denominator, which is 81.
1/3 + 15/81 = 27/81 + 15/81 = 42/81
The expression simplifies to 42/81, which can be further simplified as a fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3.
42/81 ÷ 3/3 = 14/27
Therefore, the expression simplifies to 14/27.
