The formula for the area of any triangle is as followed:

-------------------------------------------------------------------------------------------------------------
<u>Let Statements:</u>
Let the variable...
→
represent the length of the base of the triangle
→
represent the length of the height of the triangle
-------------------------------------------------------------------------------------------------------------
Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:

Distribute the parenthesis<em> (The Distributive Property) </em>:


Reduce the fraction to lowest terms:

Add -6 to both sides of the equation:


Divide both sides of the equation by 2:

Answer:
2:25
Step-by-step explanation:
Time=distance/speed
81/36=2.25
2:25 is the time for how long this will take!
We want to use a matrix to solve
-8x - 8y = -16
6x - 9y = -108
Before solving, simplify the equations as follows:
Divide the first equation by -8 to obtain
x + y = 2 (1)
Divide the second equation by 3 to obtain
2x - 3y = -36 (2)
In matrix form, the equations are

The determinant of the matrix is
D = (1)(-3) - (1)(2) = -5
Use Cramer's Rule.

Answer: (-6, 8) or x = -6, y = 8
Answer:31/40
Step-by-step explanation:
To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.
