Answer:
Step-by-step explanation:
so you will move constant to the right side and change the sign. 72x=223-7
then you will subtract the numbers 72x=223-7 and that will give you 72=216
then you will divide both sides by 72 and that will give you
- x=3 .

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.
