In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system. The equations in the system can be linear or non-linear.

• 1.

### A system of equations is a collection of .... with a same set of unknowns.

• A.

Two or more equations

• B.

One

• C.

None

• D.

Below two

A. Two or more equations
Explanation
A system of equations is a collection of two or more equations that are solved simultaneously. In this type of system, all the equations share the same set of unknown variables. By solving the system of equations, the values of the unknown variables can be determined.

### In ...., an equations is a statement of an equality containing one or more variables.

• A.

Music

• B.

Mathematics

• C.

Sociology

• D.

Biology

B. Mathematics
Explanation
An equation is a statement of equality that includes variables. In mathematics, equations are used to represent relationships between quantities and to solve for unknown values. They are an essential tool in algebra and other branches of mathematics for expressing mathematical concepts and solving problems. Equations can involve one or more variables, allowing for the representation of complex relationships and the exploration of various mathematical phenomena.

### Mathematics is usually studied in ....

• A.

Home

• B.

School

• C.

Museum

• D.

Studio

B. School
Explanation
Mathematics is usually studied in school because it is a subject that requires structured learning and guidance from teachers. Schools provide a dedicated environment for students to learn and practice mathematical concepts, with access to resources such as textbooks, calculators, and other educational materials. Additionally, schools offer opportunities for students to collaborate with peers, participate in classroom discussions, and receive immediate feedback from teachers, which are crucial for understanding and mastering mathematical concepts.

### Who is not a scientist here?

• A.

Bill Nye

• B.

Albert Einstein

• C.

Isaac Newton

• D.

Shawn Carter

D. Shawn Carter
Explanation
Shawn Carter is not a scientist because he is better known by his stage name, Jay-Z, and is primarily known as a rapper and entrepreneur. While Bill Nye, Albert Einstein, and Isaac Newton are all renowned scientists in their respective fields, Shawn Carter does not have any notable scientific contributions or background.

### What does an equal sign look like?

• A.

• B.

>

• C.

+

• D.

=

D. =
Explanation
An equal sign is represented by the symbol "=" in mathematics. It is used to indicate that two quantities or expressions are equal to each other. The "=" sign is placed between the two quantities being compared, with the quantity on the left side being equal to the quantity on the right side. This symbol is commonly used in equations and mathematical statements to show balance or equivalence.

### A ..... is a symbol for a number we don't know yet.

• A.

Constant

• B.

Variable

• C.

Coefficient

• D.

Operator

B. Variable
Explanation
A variable is a symbol for a number we don't know yet. It is used to represent unknown values or quantities in mathematical equations or expressions. Unlike constants, which have fixed values, variables can take on different values depending on the context or situation. They are often represented by letters or symbols and are commonly used in algebra and other branches of mathematics to solve equations and analyze relationships between quantities.

Rate this question:

• 7.

### A  number on its own is called a .....

• A.

Constant

• B.

Coefficient

• C.

Operator

• D.

Variable

A. Constant
Explanation
A number on its own is called a constant because it is a fixed value that does not change. Unlike variables, which can vary in value, constants have a specific and unchanging numerical value. In mathematical equations or expressions, constants are often represented by specific symbols or values that remain constant throughout the calculation.

Rate this question:

• 8.

### A ..... is a number used to multiply a variable

• A.

Variable

• B.

Operator

• C.

Constant

• D.

Coefficient

D. Coefficient
Explanation
A coefficient is a number used to multiply a variable. In mathematical equations, a coefficient represents the scale or magnitude of the variable. It determines how the variable is affected or scaled in relation to other terms in the equation. Coefficients can be positive, negative, or zero, and they help in determining the overall behavior and relationship between variables in an equation.

Rate this question:

• 9.

### An/a .... is a symbol (such as +, ×, etc) that shows an operation (ie we want to do something with the values).

• A.

Operator

• B.

Variable

• C.

Constant

• D.

Coefficient

A. Operator
Explanation
An operator is a symbol that represents a specific operation to be performed on values. It could be a mathematical operation like addition (+) or multiplication (×), or even a logical operation like AND or OR. Operators are used to manipulate and combine values in order to produce a desired result.

Rate this question:

• 10.

### The .... (such as the 2 in x2) says how many timesto use the value in a multiplication.

• A.

Operator

• B.

Coefficient

• C.

Constant

• D.

Exponent

D. Exponent
Explanation
The exponent in an expression, such as the 2 in x^2, indicates how many times to use the value in a multiplication. It represents the power to which a number or variable is raised. In this case, the exponent of 2 means that the value of x is multiplied by itself twice.
