Question

Svetlana's hair is 4 cm long. Her hair grows 1.5 cm per month. Svetlana wants her hair to be less than 16 cm long. Write an inequality to determine the number of months, m, Svetlana can allow her hair to grow so that it is less than 16 cm long.

Answer 1

Answer:  The required inequality is $4+1.5m$

Step-by-step explanation:  Given that Svetlana's hair is 4 cm long and her hair grows 1.5 cm per month. Svetlana wants her hair to be less than 16 cm long.

We are to write an equality to determine the number of months, m, Svetlana can allow her hair to grow so that it is less than 16 cm long.

The total length of her hairs in months 'm' is given by

$4+1.5\times m=4+1.5m.$

Since Svetlana can allow her hair to grow so that it is less than 16 cm long, so we must write

$4+1.5m$

Thus, the required inequality is $4+1.5m$

Answer 2

Answer:

m ≤ (16 - 4) : 1.5

Step-by-step explanation:

m ≤ 8 months
