When we <em>divide </em>both sides of the <em>inequality</em>,

3x > 27 by 3,  <em>3x(3) > 27(3)</em>

we get x > 9, as the <em>simplified form </em>of the<em> inequality.</em>

Thus, giving us the answer of:

<em>x > 9</em>

hammer [34]

Answer:

Sally has been measuring the tree for 4 months

Step-by-step explanation:

The correct question is as follows;

Sally has been measuring the tree in her yard for a science project. The tree has grown 1/2 of an inch each month and grown a total of 2 inches taller. How many months has Sally been measuring this tree?

.........................................................................................

Solution;

The tree has grown 1/2 of an inch each month and has grown a total of 2 inch taller.

We now need to know the number of months in which the measuring has been taking place.

To know the number of months, we simply need to divide the change in height which is 2 inch by the individual month growth rate which is 1/2 inch

So mathematically, that would be 2/1/2 = 2 * 2 = 4 months
