In the expression  x - 53 - 4x - w + 6x + 8  , -53 is a 

• Coefficient

• Constant

• Variable 

• None of these

Answer explanation

In the expression x - 53 - 4x - w + 6x + 8, -53 is a constant because it does not change and does not contain any variable. Constants are fixed values, while coefficients are numbers multiplying variables.

In the expression  x - 53 - 4x - w + 6x + 8  , -4x is a 

• Term

• Variable

• Coefficient

• Constant

Answer explanation

In the expression x - 53 - 4x - w + 6x + 8, -4x is a term. A term is a single mathematical expression that can include numbers, variables, and coefficients. Here, -4x represents a term involving the variable x.

In the expression  x - 53 - 4x - w + 6x + 8  , the coefficient on the term "x" is

• 0

• There is no coefficient

• 1

• -1

Answer explanation

To find the coefficient of x in the expression x - 53 - 4x - w + 6x + 8, combine like terms: 1x - 4x + 6x = (1 - 4 + 6)x = 3x. The coefficient is 3, but the question asks for the coefficient of x, which is 1. Thus, the correct answer is 1.

2f + f

• 3f

• 2f

• f

Answer explanation

To simplify 2f + f, combine like terms. 2f represents two parts of f, and adding another f gives a total of 3f. Therefore, the correct answer is 3f.

Simplify the expression: 2x + 1 + 7x 

• 10x

• 10

• 9x + 1

• 9 + 1x

Answer explanation

To simplify 2x + 1 + 7x, combine like terms: 2x + 7x = 9x. Then, add the constant 1. The final expression is 9x + 1, which matches the correct answer choice.
