Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.
Subtract 9a from both sides to get a on the left side of the equation.
5 + 5a = -5
Subtract 5 from both sides of the equation to isolate the term with a.
5a = -10
Divide both sides of the equation by 5 to solve for a.
a = -2
Let the amount be x.
6% for the first 160000
= 6/100 * 160000 = 9600
4% for any amount exceeding 160000.
= 4/100 * (x -160000) = 0.04(x-160000)
The sum of both commission should be equal to 10560.
9600 + 0.04(x -160000) = 10560
0.04(x -160000) = 10560 - 9600
0.04(x -160000) = 960 Divide by 0.04.
(x -160000) = 960/0.04
(x -160000) = 24000
x = 24000 + 160000 = 184000.
Selling price = 184000
Answer:
<u><em>What is the importance of polynomial functions?</em></u>
<u><em>
</em></u>Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.

<u><em>How these real-life applications improve or contribute to the value of life?</em></u>
Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
Answer:
rate is 8 miles per hour and he travels 40 miles per 5 hours
Step-by-step explanation:
The story problem told that i should assume that 1 mile is 1.6 km
so 5km/hr is equal to 8m/h
i got it by multiplying 5 by 1.6 so i can change from the unit km to mile
so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40
40miles per 5hrs
hope i made it clear
The mean is equal for Group A and Group B.
<h2>Given </h2>
Two groups of students were asked how far they lived from their school.
The table shows the distances in miles:
Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8
<h3>What is mean?</h3>
The mean of any data set or observation is equal to the sum of all the observations and divided by the number of observations.
The formula used to calculate the mean is;
The mean of group A is;
The mean of group B is;
Hence, the mean is equal for Group A and Group B.
