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.

(9 ⋅ 5) ⋅ 2 is equal to 9 × (5 × 2).

how was the expression rewritten

The expression (9⋅5)⋅2 was rewritten as 9⋅(5⋅2) by using the associative property of multiplication. According to this property, the grouping of factors can be changed without changing the result. In this case, we moved the group of factors (5⋅2) from the first set of parentheses to the second set, while keeping the order of the factors the same.

(9⋅5)⋅2 equals

(9⋅5)⋅2 equals 90.
