Question

One fourth of n is 3 more than 2
(a) n/4 – 2 = 3
(b) n/4 + 2 = 3
(c) n/2 – 4 = 3
(d) n/2 + 4 = 3

Answer 1

Answer:

(d) n/2 + 4 = 3

Step-by-step explanation:

Substitution: ‘Find the value of 2x + 3 if x = 4.’ In this case the pronumeral is given the value 4.

Solving an equation: ‘Find x if 2x + 3 = 8.’ Here we are seeking the value of the pronumeral that makes the sentence true.

Identity: ‘The statement of the commutative law: a + b = b + a.’ Here a and b can be any real numbers.

Formula: ‘The area of a rectangle is A = lw.‘ Here the values of the pronumerals are connected by the formula.

Equation of a line or curve: ‘The general equation of the straight line is y = mx + c.’

Here m and c are parameters. That is, for a particular straight line, m and c are fixed.

Answer 2

Given : one fourth of n is 3 more than 2

To Find : correct option

(a) n/4 – 2 = 3

(b) n/4 + 2 = 3

(c) n/2 – 4 = 3

(d) n/2 + 4 = 3

Solution:

3 more than 2

= 2 + 3

one fourth of n  = (1/4) n

= n/4

Equate both

=> n/4  = 2 + 3

Subtract 2 from both sides

=> n/4  - 2  = 2 + 3 - 2

=> n/4  - 2  =  3

(a) n/4 – 2 = 3  is the correct option
