Example Question #11 : Solve Word Problems Leading To Equations: Ccss.Math.Content.7.Ee.B.4a
If a rectangle possesses a width of and has a perimeter of , then what is the length?
In order to solve this problem, we need to recall the formula for perimeter of a rectangle:
We can substitute in our known values and solve for our unknown variable (i.e. length):
We want to isolate the to one side of the equation. In order to do this, we will first subtract from both sides of the equation.
Next, we can divide each side by
The length of the rectangle is

Example Question #1 : Systems Of Inequalities
Solve the following inequality for . Round your answer to the nearest tenth.
The first step is to square each side of the inequality.
Now simplify each side.
Now subtract the left side of the inequality to make it zero, so that we can use the quadratic formula.
Now we can use the quadratic formula.
Recall the quadratic formula.
Where , , and , correspond to coefficients in the quadratic equation.
In this case , , and .
Now plug these values into the quadratic equation, and we get.
Now since we are dealing with an inequality, we put the least value on the left side, and the greatest value on the right. It will look like the following.
