Write an algebraic expression for '10 less than x'.

• x - 10

• 10 - x

• x + 10

• 10 + x

Answer explanation

The algebraic expression for '10 less than x' is 'x - 10'. The phrase 'less than' in mathematical terms translates to a subtraction operation. The number 10 is being 'subtracted from' or is 'less than' x, which gives us 'x - 10'. The other options are incorrect as they either represent 'x less than 10' or are adding 10 to x.

Write an algebraic expression for '3.7 minus f'.

• f - 3.7

• 3.7 - f

• f + 3.7

• 3.7 + f

Answer explanation

The question asks for an algebraic expression for '3.7 minus f'. The correct expression for this is '3.7 - f'. This is because we are subtracting 'f' from '3.7', and not the other way around. None of the other options correctly represent this.

Write an algebraic expression for 'x multiplied by 6'.

• 6 - x

• 6x

• x / 6

• 6 / x

Answer explanation

The question asked for an algebraic expression for 'x multiplied by 6'. The correct choice, 'x - 6', is incorrect because it represents subtraction, not multiplication. There seems to be a discrepancy between the question and the answer. A correct expression for 'x multiplied by 6' would be '6x'.

Write an algebraic expression for '3.3 plus the product of 2 and h'.

• 3.3 + 2h

• 2h + 3.3

• 3.3 - 2h

• 2h - 3.3

Answer explanation

The question is asking for a mathematical expression that represents '3.3 plus the product of 2 and h'. The correct answer is '3.3 + 2h', which is the exact representation of the given phrase. '2h' represents the product of 2 and h, and '3.3 + 2h' adds 3.3 to that product.

Write an algebraic expression for '5 less than c'.

• c - 5

• 5 - c

• c + 5

• 5 + c

Answer explanation

The algebraic expression for '5 less than c' is 'c - 5'. This is because '5 less than c' means we subtract 5 from c. The option '5 - c' is incorrect because this represents 'c less than 5', not '5 less than c'. The options 'c + 5' and '5 + c' are also incorrect as they represent an addition, not a subtraction.

Write an algebraic expression for '2.5 more than d'.

• d + 2.5

• 2.5 + d

• d - 2.5

• 2.5 - d

Answer explanation

The algebraic expression for '2.5 more than d' is '2.5 + d'. This is because when something is 'more than' a number, it means that amount is being added to the original number. Therefore, the correct choice is '2.5 + d'.

Write an algebraic expression for 'a number q tripled'.

• 3q

• 3-q

Answer explanation

The question asks for the algebraic expression of 'a number q tripled'. This can be written as 'q * 3' or '3 * q' as multiplication is commutative. However, the correct answer is given as 'q * 3', suggesting the order of multiplication matters in this context.
