Question 1.
Write the expressions for the following statements.
(i) 5 is added to three times z
(ii) 9 times ‘n’ is added to ’10’
(iii) 16 is subtracted from two times ‘y’
(iv) ‘y’ is multiplied by 10 and then x is added to the product
i) Given 5 is added to three times z
three times z = 3z 5 is added to three times z = 3z + 5

ii) Given 9 times n is added to 10
9 times n = 9.n
9 times ‘n’ is added to 10 = 9n + 10

iii) Given 16 is subtracted from two times y
two times y = 2.y
16 is subtracted from two times y = 2.y – 16

iv) Given y is multiplied by 10 and then x is added to the product, y is multiplied by 10 = 10.y
x is added to the product = 10.y + x

Question 2.
Peter has ‘p’ number of balls. Number of balls with David is 3 times the balls with Peter. Write this as an expression.
Given, number of balls with Peter = p
Number of balls with David = 3 times with the Peter
= 3.p
