Svetlana's hair is 44 centimeters long. her hair grows 1.51.5 centimeters per month. svetlana wants her hair to grow so that it is at least 77 centimeters long. write an inequality to determine the number of months, mm, it will take svetlana's hair to grow so it is at least 77 centimeters long.

Step-by-step explanation:

Let m be the number of months.

It has been given that Svetlana's hair is 4 centimeters long. So 4 will be constant for our equation.

Her hair grows 1.5 centimeters per month. So the length of Svetlana's hair after m months will be 1.5m.

Svetlana wants her hair to grow so that it is at least 7 centimeters long. So the length of svetlana's hair after n months plus 4 should be greater than or equal to 7.

We can represent this information in an equation as:

Therefore, the inequality   will represent the number of months, m, it will take Svetlana's hair to grow at least 7 cm long.
