Step-By-Step Explanation:
1. Take 9 • 11 = 99
2. Take 10 / 2 = 5
3. Take 2 + 10 - 99 = -87
So -87 would be your final answer. Hope that helped!

If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase. 
- Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.
- To find the average, sum all the values in the set. Then divide the total by the number of values. 
 We have the current examination mean, xold = 97.2
Now, we receive,  x = 99 on the next examination, the new mean will be:
 xnew = (xold + x)/N 
 xnew = (97.2+99)/2 
 xnew = 196.2/2 
 xnew = 98.1  
 
 The new average is 98.1 
 
 98.1 > 97.2 
 So if you score 99 on your next exam, your average will increase.

An equation which can be used to solve the given system of equations is 3x⁵ - 5x³ + 2x² - 10x + 4 = 4x⁴ + 6x³ - 11.
<u>Given the following data:</u>
y = 3x⁵ - 5x³ + 2x² - 10x + 4
y = 4x⁴ + 6x³ - 11
<h3>What is a system of equations?</h3>
A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneoulsy.
Equating the given equations, we have:
y = y
3x⁵ - 5x³ + 2x² - 10x + 4 = 4x⁴ + 6x³ - 11
3x⁵ - 5x³ + 2x² - 10x + 4 - (4x⁴ + 6x³ - 11) = 0
3x⁵ - 5x³ + 2x² - 10x + 4 - 4x⁴ - 6x³ + 11 = 0
3x⁵ - 5x³ + 2x² - 10x + 4 - 4x⁴ - 6x³ + 11 = 0
3x⁵ - 4x⁴ - 11x³ + 2x² - 10x + 15 = 0
