Question 1 :

Write the algebraic expressions for the following :

Sum of x and twice y

Solution :

Twice y  =  multiply 'y' be 2 -----> 2y

Sum of x and twice y :

x + 2y

Question 2 :

Write the algebraic expressions for the following :

Subtraction of z from y

Solution :

Subtraction of z from y :

y - z

Question 3 :

Write the algebraic expressions for the following :

Twice the sum of m and n

Solution :

Sum of m and n  =  m + n

Twice  =  multiply by 2

Twice the sum of m and n :

2(m + n)

Question 4 :

Write the algebraic expressions for the following :

b is  decreased by twice a

Solution :

Twice a  =  multiply 'a' by 2 -----> 2a

b is decreased by twice a :

b - 2a

Question 5 :

Write the algebraic expressions for the following :

Sum of x squared and y squared

Solution :

Square of x  =  x2

Square of y  =  y2

Sum of x squared and y squared :

x2 + y2

Question 6 :

Write the algebraic expressions for the following :

Two times the product of a and b divided by 5

Solution :

Two times the product of a and b  =  2ab

Two times the product of a and b divided by 5 :

2ab / 5

Question 7 :

Write the algebraic expressions for the following :

Product of p and q added to 7

Solution :

Product of p and q  =  pq

Product of p and q added to 7 :

pq + 7

Question 8 :

Write the algebraic expressions for the following :

x more than two-thirds of y

Solution :

Two-thirds of y  =  (2/3)y

x more than two-thirds of y :

x + (2/3)y

Question 9 :

Write the algebraic expressions for the following :

Half a number x decreased by 3

Solution :

Half a number x  =  (1/2) x

Decreased by 3  =  - 3

Half a number x decreased by 3 :

(x/2) - 3

Question 10 :

Write the algebraic expressions for the following :

Sum of numbers m and n decreased by their product

Solution :

Sum of numbers m and n  =  m + n

Decreased by their product  =  -mn

Sum of numbers m and n decreased by their product :

(m + n) - mn

Question 11 :

Write the algebraic expressions for the following :

4 times x less than sum of y and 6

Solution :

4 times x  =  4x

Sum of y and 6  =  y + 6

4 times x less than sum of y and 6 :

4x - (y + 6)

Question 12 :

Write the algebraic expressions for the following :

Double the sum of one third of a and m.

Solution :

One third of a and m  =  (1/3)a + m

Double =  multiply by 2

Double the sum of one third of a and m :

2[(1/3)a + m] Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here.
