The total cell phone bill of Jenya for a month is $102.50.
What is Multiplication?
Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Jenya paid $40 per month for a cell phone plus $1.25 for each international text message she sent.
Fixed bill for the month = $40
Cost for each international text message = $1.25
Total number of messages = 50
Total cost for the international text message = $1.25 × 50
= $62.50
Total cost of bill for the month = $62.50 + $40
= $102.50
Hence the total phone bill for the month is $102.50.

The first two steps work for solving large perfect squares as well.
1. Divide your number into perfect square factors.
2. Take the square roots of your perfect square factors.
3. If your number doesn't factor perfectly, reduce your answer to simplest terms.
4. If needed, estimate. In some cases if you have memorized some of the square roots, you can estimate where the number would be.
ie.
5. Alternatively, reduce your number to its lowest common factors as your first step. Finding perfect square factors isn't necessary if you can easily determine a number's prime factors (factors that are also prime numbers).
ie.

The required number line has been attached which represents the given information.
What is Number Line?
In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
We have been given that a child must be greater than or equal to 36 inches tall and less than 48 inches tall.
Let the height of the child would be x
According to the given situation, we can write the inequality would be as:
⇒ 36 ≤ x < 48
As per the above inequality, we can draw the required number line.
Thus, the required number line has been attached which represents the given information.

Do inverse operation and apply to both sides of the equation.
3s+8=29
-8 -8
3s=21
Now we must do the inverse operation of multiplication, which is division.
3s=21
3s/3=21/3
s=7
We are left with s=7
Our final answer s=7
Now we must check our work by plugging the answer into our equation.
3(7)+8=29
21+8=29
CORRECT ANSWER! :P
