Answer:
We conclude that the first line number represents 1.5 + 2.5.
Step-by-step explanation:
Given the expression
It means the first segment must represent 1.5 units starting from 0.
Since we have to add 2.5 to 1.5, so the next segment must represent 2.5 units, starting from 1.5
Combining them would make
Now, if we observe the first number line,
- The first arrow represents the 1.5 units starting from 0.
- The second arrow represents the 2.5 units starting from 1.5.
- The combined units of both arrows represent the length of 4 units. i.e. 1.5 + 2.5 = 4
Thus, we conclude that the first line number represents 1.5 + 2.5.

Answer:
(a) 3 added to twice the value of n
(b)
Step-by-step explanation:
Given
Table #27
Solving (a): First, we express as an equation
The table illustrates a linear function; so, we calculate the slope (m) first
Where:
So:
The equation is then calculated using:
In words, the equation is: <em>3 added to twice the value of n</em>
Solving (b): As an equation.
This has been solved in (a) above:
