Test: Algebraic Expressions - Question 1

What are the coefficients of x in the expression 8 – x + y?

Detailed Solution for Test: Algebraic Expressions - Question 1

Coefficient of x is the constant with x which is -1 in this case.

Test: Algebraic Expressions - Question 2

What is the coefficient of x in the expression y2x + y?

Detailed Solution for Test: Algebraic Expressions - Question 2

Coefficient of a variable is the integral number(or the expression) written next to a given variable. For x, the coefficient is y2.

Test: Algebraic Expressions - Question 3

Which of the following pairs of terms is a pair of unlike terms?

Detailed Solution for Test: Algebraic Expressions - Question 3

The correct option is B −4yx2,−4xy2

−p2q2,12q2p2: terms contain same variables with equal exponents, so these are like terms.
 

−4yx2,−4xy2: As in −4yx2, x has exponent 2 & y has exponent 1 and in −4xy2 , y has exponent 2 & x has exponent 1. So both the terms have same variables but with different exponent. Hence −4yx2,−4xy2 are unlike terms.

41, 100: terms do not contain any variable, so these are like terms.

qp2,13p2q: terms have same variables p and q with equal exponent 2 and 1 respectively. So, these are like terms.

Test: Algebraic Expressions - Question 4

Write the expression for the statement: the sum of three times x and 11.

Detailed Solution for Test: Algebraic Expressions - Question 4

Three times of x is 3 multiplied by x which is 3x . sum of 3x and 11 is 3x plus 11 which is 3x + 11

Test: Algebraic Expressions - Question 5

Write an expression: Raju's father's age is 5 years more than 3 times Raju s age. If Raju's age is x years, then his father’s age is

Detailed Solution for Test: Algebraic Expressions - Question 5

Raju's age is x. Since the father’s age is 3 times Raju's age and 5 more, so three times Raju's age is 3x and 5 more, which means 3x+5.

Test: Algebraic Expressions - Question 6

If the value of the expression x2 – 5x + k for x = 0 is 5, then the value of k is

Detailed Solution for Test: Algebraic Expressions - Question 6

Put value of x in the given expression:  (0)2 - 5 x (0) + k = 5
                                                                       k = 5

Test: Algebraic Expressions - Question 7

The number of terms in 4p2q − 3pq+ 5 is

Detailed Solution for Test: Algebraic Expressions - Question 7

Number of terms means the total number of individual elements present in a statement.

We have 4p2q, 3pq2 and 5 separated by a plus or minus sign, so these three are our terms.

Test: Algebraic Expressions - Question 8

The expression for sum of numbers a and b subtracted from their product is

Detailed Solution for Test: Algebraic Expressions - Question 8

Sum of numbers is (a+b) , its product is ab and we have to subtract sum from product , so its ab-(a+b)

Test: Algebraic Expressions - Question 9

The sum of mn + 5 – 2 and mn + 3 is

Detailed Solution for Test: Algebraic Expressions - Question 9

When we combine mathematical terms, we perform operations on the like terms only.Hence, mn+5–2 + mn + 3 = (mn + mn) + (5 - 2 + 3) = 2mn + 6.

Test: Algebraic Expressions - Question 10

What must be added to 5x- 2x2 + 6x - 7 to make the sum x3 + 3x2 - x + 1 ?

Detailed Solution for Test: Algebraic Expressions - Question 10
