Answer explanation

The coefficient of y in 6y is 6. Therefore, the correct answer is 6.

• -6

• 6

• 0

• 1

Answer explanation

The coefficient of y in -6y is -6. The number directly in front of the variable y represents its coefficient.

• 5x + 8

• 8x + 5

• 5 + 8x

• 8 + 5x

Answer explanation

To express '8 more than 5x,' we write it as 8 + 5x. Therefore, the correct expression is 8 + 5x.

• 72u

• 17u

• 72

• 9u + 8

Answer explanation

To find the product of 9u and 8, multiply the numbers: 9u * 8 = 72u. Therefore, the simplified expression is 72u.

• 4y - 9

• 4y + 9

• 9 - 4y

• 9 + 4y

Answer explanation

The correct algebraic expression for 'four times y, take away 9' is 4y - 9, which matches the expression 4y - 9.

Answer explanation

Choose the worded expression that matches the algebraic expression 9y - 3. The correct choice is '3 less than the product of 9 and y.'

Answer explanation

The correct expression is obtained by first finding 2 less than 5x, which is 5x - 2. Then, multiplying by 3 gives 3(5x - 2), and finally dividing by 9 results in the expression 3(5x - 2) / 9.
