Answer: Heyaa! ~
Your Answer is... (-7, 13) Which is C.
Step-by-step explanation:
Factor then solve to find the complex solutions.
Remove the absolute value term. This creates a ±
on the right side of the equation because |x|=±x.
R−3=±10
The complete solution is the result of both the positive and negative portions of the solution.
R= -7, 13

Ron used a combination of 45-cent stamps and 1-cent stamps to mail a package. He used 15 stamps in all. If the total cost for postage was $4.55, how many 1-cent stamps did he use?
Answers
Answer:
Then the count of 1 cent stamps is 15 −x. So for total cost we have. [45x + 1(15 − x)]cents = $4.55. but there are 100 cents in 1 dollar so we change the above to. [45x +1(15 −x)] 100 = 4.55. Multiply both sides by 100. 45x + 15− x = 455. 44x = 440.

what does PEMDAS mean in math
Answers
Hey there!
PEMDAS simply means (the OVERALL question answer)
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
Here’s an example
24 - 4^2 + 2 * 4
= 24 - 16 + 2 * 4
= 24 - 16 + 8
= 8 + 8
= 16
Thus, the answer for that equation is: 16
Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

PEMDAS is the order that you solve a problem.
PEMDAS stands for:
Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction
If you have an equation or expression that you need to solve, you solve it in this order. You do the parenthesis first, then you solve the exponents, then you do the multiplication and division from left to right, and last you do addition and subtraction from left to right.
In the equation
2 + 3 * 5,
first you would do 3 * 5 because multiplication is before addition.
2 + 15
Then you would do the addition to get the answer:
17.

3 semicircles are connected to 3 sides of a square. each side of the square measures 4 centimeters. what is the area of the composite figure? (6π 4) cm2 (6π 16) cm2 (12π 4) cm2 (12π 16) cm2
Answers
The area of the composite figure with 3 semicircles connected to 3 sides of a square is (6π+16)[tex]cm^{2}[/tex].
What is a semicircle?A semicircle is a plane shape that is a part of a circle divided into two equal parts through its diameter.
Analysis:
Since the semicircles are connected to 3 sides of a square 4cm, the diameter of the semicircle is 4cm.
Radius of semicircle = 4/2 = 2cm
Area of a semicircle = π[tex]r^{2}[/tex]/2 = [tex]\pi[/tex][tex](2)^{2}[/tex]/2 = 2π[tex]cm^{2}[/tex]
For three semicircles = 3 x 2π[tex]cm^{2}[/tex] = 6π[tex]cm^{2}[/tex]
Area of square = [tex]s^{2}[/tex] = [tex](4)^{2}[/tex] = 16[tex]cm^{2}[/tex]
Area of composite figure = Area of 3 semicircles + area of square
Area of composite figure = (16 + 6π)[tex]cm^{2}[/tex]
In conclusion, the area of the composite figure is (16 + 6π)[tex]cm^{2}[/tex].

How do I graph this?Y=4x+1 and Y=x-2? My teacher said that they have to cross each other
Answers
This is called system of equations because you are searching a pair of numbers that inserted as x and y verify both equations at the same time.
To solve a system of equation you have to use one equation to express one variable as a function of the other, and substitute the result in the second equation.
In your case you have
y = x - 2
So your y variable will be always equal to x - 2 , even in the second equation. Then we can write
x - 2 = 4x + 1
Here I replaced the "value" of y in the second equation.
Now you have an equation in one variable that you can solve as usual
x - 2 = 4x + 1
4x - x = - 2 - 1
3x = -3
x = -1
With a value for x you can substitute in one of the two equations and obtain y. Because both equations has to be valid at the same time, both equations must give you the same number for y. Let's try:
y = x - 2
y = - 1 - 2
y = -3
and, with the second equation
y = 4x + 1
y = 4 ( - 1 ) + 1
y = - 4 + 1
y = -3
It works! Then our solution is given by x = -1 and y = -3.
To graph this, simply plot these coordinates.

Dylan is going to the fair and has $35. He is going to use $5 for food. The admission is $7, and rides are $1.85 each.
Which of the following equations could you use to find how many rides Dylan can go on?
$12 = $35 + $1.85 x
$35 = $1.85 + $12 x
$1.85 x = $47
$35 = $12 + $1.85 x
Answers
Answer:
$35 = $12 + $1.85x
Step-by-step explanation:
the total is 35 so it is alone on the left side of the equal sign
then 5 + 7 is 12 and he has to spend $12
rides are 1.85 each so there is a x next to it

6/6 + 6/6 + 6/6 + 3/6 + 2/6The given expression can also be written as;
⇒ (6/6 + 6/6 + 6/6) + (3/6 + 2/6)When simplified, we get;
⇒ {1 + 1 + 1} + {(3 + 2)/6} ⇒ {3} + {(5)/6}When we open the parentheses and the curvy brackets, we get;
⇒ {3} + {(5)/6} ⇒ 3 + (5)/6⇒ 3 + 5/6Finally, we can see that 3 is a whole number. Therefore,
⇒ 3 + 5/6⇒ 3 5/6 (Option D)Therefore, Option D is correct.
Answer:

B:149 dollars and 4 cents
C:136 dollars and 12 cents

Answers
Answer:
D
Step-by-step explanation:
100% = $143.74
1% = 100%/100 = 143.74/100 = $1.4374
5.3% = 1%×5.3 = 1.4374 × 5.3 = $7.61822
$143.74 + 5.3% = $143.74 + $7.61822

Answers
Answer: If you meant (x^2 + 5x - 36)/(x^2-16) then the answer is: (x+9)/(x-4)
Step-by-step explanation:
This is just factoring, you can use guess and check.
If you take just the numerator: x^2+5x-36 and factor. To factor consider -36, and the multiples that can add up to 5 (from 5x).
x^2 + 5x - 36/(x^2-16)
The denominator is actually a rule of (a+b)(a-b) which in this case (x+4)(x-4)
(x+9)(x-4)/(x-4)(x+4)
Now just divide like terms which is the (x-4)/(x-4)=1

The table shows the estimated sales for two different prices of bags of chips. Calculate the profit per bag for the bags sold at $1 each.
Answers
The profit per bag for the bags sold at $1 each is 0.35
The correct option is: (D)
What is profit?Profit is the positive financial gain remaining after all costs, taxes, and expenses have been deducted from total sales.
Profit per bag for the bags sold at $1 each be,
Profit = (Estimated sales -(Estimated Sales* Variable cots +Fixed cost))/Estimated Sales
We know,
Estimated sales= 1600000
Variable cost = 0.40
Fixed cost= 400000
So, Profit = [tex]\frac{1600000-(1600000*0.40+400000)}{1600000}[/tex]
= [tex]\frac{1600000-(1040000)}{1600000}[/tex]
= [tex]\frac{560000}{1600000}[/tex]
= 0.35
Hence, the profit per bag be 0.35.
