Answer:
11/20 ; 0.55
Step-by-step explanation:
11= 20x
20x= 11
x= 11/20 ; 0.55
Answer:
x = −9
Step-by-step explanation:
Step 1: Simplify both sides of the equation
11 = x + 20
Step 2: Flip the equation
x + 20 = 11
Step 3: Subtract 20 from both sides
x + 20 − 20 = 11 − 20
x = −9

Which answer choice identifies the relevant information in the problem?
Sarah left the house at 12:15 p.m. to go to the store. She spent $42.20 on 2 books for her children and she spent $5.67 on a toys for her dog, Rover. Sarah arrived home at 1:00 p.m. How much did Sarah spend on each book
Answer:
Step-by-step explanation:
Given parameters:
Time of going out = 12:15pm
Amount spend on two books = $42.20
Amount spend toys = $5.67
Time of arrival = 1:00pm
The amount Sarah spent on each of the two books;
= [tex]\frac{total amount spent on the books }{number of books}[/tex]
Amount spent on each books = [tex]\frac{42.20}{2}[/tex] = $21.1 per book
The relevant information to solve this problem are the number of books and the cost of the book.

Use the graph and the translation (x,y) → (x + 4y + 2) to answer parts a and b below.
a. Enter the image of each vertex as an ordered pair.
A → A
B → B
C → C
Use the translation formula to determine the new points.
A' → [tex](5 + 4, -8 + 2) = (9, -6)[/tex]
B' → [tex](1 + 4, -1 + 2) = (5, 1)[/tex]
C' → [tex](-7 + 4, -3 + 2) = (-3, -1)[/tex]
A' = (9, -6)
B' = (5, 1)
C' = (-3, -1)
The new coordinates are obtained as A'(-4, 7), B'(3, 1) and C'(-3, -1) respectively.
How to transform a graph of the function?The graph of a function can be transformed by either shifting it in the right, left, up or down.
When the transformation is rightwards, the function becomes as f(x - a).
For left shifting it is f(x + a).
And, for up and down shift it is a + f(x) and a - f(x) respectively.
The new coordinates after the transformation is given as follows,
Apply the given transformation (x,y) → (x + 4,y + 2) as below,
The coordinates of A' are (-8 + 4, 5 + 2) = (-4, 7).
The coordinates of B' are (-1 + 4, -1 + 2) = (3, 1).
The coordinates of C' are (-7 + 4, -3 + 2) = (-3, -1).
Hence, the coordinates after the transformation become as A'(-4, 7), B'(3, 1) and C'(-3, -1).

Answer:
3 (second option)
Step-by-step explanation:
g(x) is a piecewise function. To find g(3), you have to see which condition the number 3 satisfies.
Out of the options provided, the only condition 3 satisfies is x≥3.
The equation provided for x being greater than or equal to 3 is 6 - x.
Now we can plug in our x value of 3 and solve.
g(3)= 6 - 3
g(3)= 3

Answer:
x = -149/20
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2(x + 469/20) = 32
Step 2: Solve for x
Distribute 2: 2x + 469/10 = 32Isolate x term: 2x = -149/10Isolate x: x = -149/20Step 3: Check
Plug in x to verify it's a solution.
Substitute: 2(-149/20 + 469/20) = 32Add: 2(16) = 32Multiply: 32 = 32Here we see that 32 does indeed equal 32. ∴ x = -149/20 is a solution of the equation.
And we have our final answer!

John gets a new job and receives a $500 signing bonus. After that, he makes $200 a day. How much money does he make after 4 days?
Answer:
John makes a total of $1,300.
Step-by-step explanation:
We know that before his bonus, John already has $500. Then, he gets $200 every day for 4 days.
200 x 4 = $800
So, over the course of those 4 days, Johnny makes $800. Now, let's add this to the rest of his money.
800 + 500 = $1,300
Therefore, John makes a total of $1,300.

1. What is matter
2. Write the states of matter with three examples.
Answer:
1.Matter is the "stuff" that makes up the universe — everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons
2.Matter can exist in one of three main states: solid, liquid, or gas.
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Step-by-step explanation:
Answer:
Matter is defined as anything that has mass and takes up space. The types of matter are solids, liquids, gases, and plasma. An example of solids are the desks in school,your bones, or your house. An example of liquids is the ocean, lemonade, or blood. Gases can be hydrogen, carbon dioxide, or oxygen. Plasma can be stars.

Answer:
After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25
Step-by-step explanation:
The given expression is:[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex]
First I solve the expression, and then will point the error
[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25[/tex]
So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.
The step she did was: [tex]0.38 \times 5 \times(1/20)\times3\times(-8)[/tex]
While the correct step was: [tex]0.38 \times 3 \times(-20)\times5\times(-1/8)[/tex]
After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25
