what is coefficient of the term 16x
Answer:
16
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
We are given the term:
16x
We want to find the coefficient.
A coefficient is a constant that a variable is multiplied by. Essentially, it is the number in front of the variable.
The variable in the term is x. The number that precedes the variable is 16. Therefore, the coefficient of the term must be 16.

Adam and Barb planned a used book sale for the weekend so they gathered their books and agreed on a price for hardbacks and a lower price for paperbacks. Adam sold 14 hardcover books and 20 paperbacks and earned $234 for his efforts. Barb sold 15 hardcover books and 9 paperbacks. Barb made $201. How much did they charge for each hardcover book and for each paperback?
You must show your work.
1) Mathematically what kind of problem is this called? (What concept did you apply to this problem that allowed you to solve it?)
2) Set up the problem showing the equations you’ll use. Please make sure you label or explain what your variables mean.
3) Show the math work to arrive at the answer. Please make it clear which price is hardcover and which is paperback.
Answer: hardcover books x=11 and paperbacks y=4
Step-by-step explanation:
14x+20y=234
15x+9y=201
Multiply the top equation by 9 and the bottom equation by 20 so the outcome of both equations would be 126x+180y=2106 and 300x+180y=4020 then you subtract the two equations once you do that you get 174x=1914, and the y variable cancels out, once you divide 174 from 1914 you get 11x. So the answer for how much hardcover books cost is 11 dollars. Now we have to find the y variable which we can just plug in 11 (x) into the equation. So 15(11)+9y=201 we get 165+9y=201, subtract 165 from both sides and we get 9y=36 and divide 9 from both sides and we get 4 so y=4 the cost of paperbacks are 4 dollars

Find the distance between the points R(0, 1) and S(6, 3.5). The exact distance between the two points is .
Answer:
the answer 6.5
........
The distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that:
Two points are:
R(0, 1) and S(6, 3.5)
To find the distance between points R and S we can use the distance formula.
[tex]\rm d=\sqrt{(6-0)^2+(3.5-1)^2}\\[/tex]
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
d = √(36 + 6.25)
d = √42.25
d = 6.5 units
Thus, the distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

What is the slope of the line ?
Answer:
The slope of a line characterizes the direction of a line.
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.
If x = -2, then 2x = -4.
A. Addition Property of Equality
B. Subtraction Property of Equality
C. Multiplication Property of Equality
D. Division Property of Equality
E. I'm not sure.
The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.
Option C is the correct answer.
We have,
The Multiplication Property of Equality states that if you multiply both sides of an equation by the same non-zero number, the equality still holds true.
In this case, x = -2.
Multiply both sides of the equation by 2,
2x = 2(-2) = -4
Thus,
The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.

Answer:
a = h/5
Step-by-step explanation:
If you had the equation ...
10 = 5a
and you wanted to find the value of the variable, you would divide by its coefficient:
10/5 = (5a)/5
2 = a
__
Here, we have replaced '10' with 'h'. The same (single) step applies: divide by the coefficient of 'a'.
h = 5a
h/5 = a
To put this in "a = " form, swap the sides of the equal sign:
a = h/5

Literal equations just use different symbols (h instead of 10, here). The operations are the same.
Lupe put $12,000 in a certificate of deposit that gained interest at a rate of 6.5%. How much interest did the account gain after 3 months?
Answer:
$195
Step-by-step explanation:
We use the simple interest formula.
I = Prt
I = Interest
P = Principal (initial value)
r = Interest rate
t = Time (years)
P = $12,000
r = 6.5% which we convert to a decimal by dividing by 100 6.5/100 = .065
t = 3 months which we convert to years by dividing by 12 3/12 = 1/4 = .25
Plug in the values
I = 12000 * .065 * .25
I = $195 interest gained
Answer:
195
Step-by-step explanation:
3 month is .25 years
6.5/100 = .065
12000 x .065 x .25 = 195
Write a couple sentences to explain how you would find the area of the shaded region:
Answer:
I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle
Answer:
Step-by-step explanation:
1. Find the area of the circle. Area_c = pi * r^2
2.Find the area of the pentagon in terms of the radius Area_P =
3 sqrt(3) r^2 / 2
The answer you want is Area_shade = Area_c - area_P
Area = pi * r^2 - 3 sqrt(3)r^2/2
Area = r^2 (pi - 3 sqrt(3)/2)

The two figures below, a regular hexagon and regular pentagon, have the same perimeter. What is the length of one side of the pentagon?
please solve 5p-9=2p+12
The required solution to the equation 5p - 9 = 2p + 12 is p = 7, as of the given condition.
To solve the equation 5p - 9 = 2p + 12, we will follow these steps:
Combine like terms on each side of the equation:
5p - 9 = 2p + 12
Move all the terms containing "p" to one side and the constant terms to the other side. To do this, we'll subtract 2p from both sides and add 9 to both sides:
5p - 2p - 9 + 9 = 2p + 12 - 2p + 9
Simplifying both sides:
3p = 21
Now, to solve for "p," we'll divide both sides of the equation by 3:
3p/3 = 21/3
Simplifying:
p = 7
Therefore, the solution to the equation 5p - 9 = 2p + 12 is p = 7.
