If m = 17, what is the sum of 5 and m?
- A.
85
- B.
22
- C.
21
- D.
84
Correct Answer
B. 22Explanation
If ( m = 17 ), and we want to find the sum of 5 and ( m ), we can represent it algebraically as ( 5 + m ). Then we substitute the value of ( m ) into the expression:
[ 5 + m = 5 + 17 = 22 ]
So, the sum of 5 and ( m ) when ( m = 17 ) is 22.Rate this question:

What is the difference between an expression and an equation?
- A.
They are the same thing.
- B.
An equation has an equal sign, but an expression does not.
- C.
An equation has more numbers and an expression has more variables.
- D.
An expression always has a higher value for the variable.
Correct Answer
B. An equation has an equal sign, but an expression does not.Explanation
An equation and an expression are both fundamental components of algebraic notation, but they serve different purposes. An equation represents a mathematical statement asserting the equality of two expressions and is denoted by an equal sign, such as \(x + 3 = 7\). Conversely, an expression consists of variables, constants, and operators, representing a mathematical phrase without asserting equality, like \(2x + 5\). While equations are used to solve for unknown variables, expressions are used to represent mathematical relationships or quantities. In essence, equations provide a framework for problem-solving, while expressions serve as the building blocks for mathematical operations and calculations.Rate this question:

What does 25k mean?
- A.
25 added to k
- B.
The difference between k and 25
- C.
The product of 25 and k
Correct Answer
C. The product of 25 and kExplanation
The correct answer is "the product of 25 and k". In mathematics, when two numbers are multiplied together, the result is called their product. Therefore, when we multiply 25 and k, we get the value of 25k.Rate this question:

Twenty-two times a number, a, decreased by three
- A.
22 x a - 3
- B.
3 - a x 22
- C.
22 + a x 3
Correct Answer
A. 22 x a - 3Explanation
The given expression "22 x a - 3" represents the phrase "twenty-two times a number, a, decreased by three". This can be understood by breaking down the expression: "22 x a" means multiplying 22 by a, and then subtracting 3 from the result. Therefore, the correct answer is "22 x a - 3".Rate this question:

- A.
(3 + 22) / a
- B.
A / (3 + 22)
- C.
3 + 22 / a
Correct Answer
A. (3 + 22) / aExplanation
The correct answer is (3 + 22) / a. This is because the question states that the sum of three and twenty-two should be divided by the number a. So, we first add three and twenty-two to get twenty-five, and then divide it by a.Rate this question:

Please fill answer below The ____________ of a variable is the number in front of the variable.
Correct Answer
coefficientExplanation
The coefficient of a variable in an algebraic expression is the numerical factor that is multiplied by the variable. For instance, in the expression (3x), the coefficient of (x) is (3). Similarly, in the expression (2y), the coefficient of (y) is (2). Coefficients provide information about the scale or magnitude of the variable's contribution to the expression. They help quantify the relationship between the variable and other terms in the expression. In summary, the coefficient represents the factor by which the variable is multiplied in the expression.Rate this question:

- B.
0.55
- C.
1.55
- D.
155
Correct Answer
C. 1.55Explanation
The coefficient of x in the expression 1.55x is 1.55. In algebraic expressions, the coefficient is the number that multiplies the variable. In this case, x is being multiplied by 1.55, so 1.55 is the coefficient of x.Rate this question:
