For this case, the first thing we are going to do is assume that all the tests are worth the same.
Then, we define a variable:
x: score of Mona's last test
We write now the inequality that models the problem:
From here, we clear the value of x:
Answer:
the lowest grade that Mona can get for her last test so that her test average is 90 or more is:
x = 87

<h2>The Parallelogram</h2>Step-by-step explanation:
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Also, we have two pairs of parallel sides: is parallel to , and is parallel to . So it is a parallelogram or a rhombus. Since the length of the sides are not equal, the quadrilateral is a parallelogram.
Example:
