Answer:
a) The algebraic notation is 4 ( x -3 ) = 4x -3
b) The algebraic notation is 2x +2
Step-by-step explanation:
<u><em>Explanation:-</em></u>
a)
Let 'x' be the number
Given 'x' is a number, subtract three
⇒ x - 3 and multiply '4'
The result of algebraic is 4 ( x -3 ) = 4x -3
b)
<em>Let 'x' be a number and add one</em>
⇒ (x+1) and then double
∴ The algebraic notation is
(x+1 ) (2) = 2x +2

Answer:
y = kx
Step-by-step explanation:
In proportional relationships, the value of one variable increases as the other increases or decreases as the other decreases. It is denoted mathematically as y ∝ x where x and y are the variables. It follows that
y = kx where k is the proportionality constant.
So in the relationship where x represents the number of adults, and y represents the number of students,
y ∝ x and y = kx
y = kx is the required equation
