Answer:
Mia's test score is 44 if she got 3 questions wrong.
Mia's test score is (50-2x) if she got x questions wrong.
Step-by-step explanation:
It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.
If she got 3 questions wrong, then
Deducted marks [tex]=2\times 3=6[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-6[/tex]
[tex]=44[/tex]
So, Mia's test score is 44 if she got 3 questions wrong.
If she got x questions wrong, then
Deducted marks [tex]=2\times x=2x[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-2x[/tex]
So, Mia's test score is (50-2x) if she got x questions wrong.
If SK = 8x - 9, KF = x + 3, and SF = 7x + 4,

Answer:
SF = 39
Step-by-step explanation:
What is a set of numbers are intergers but not whole numbers or natural numbers?
If you have negative numbers anywhere in the set, then that set cannot be part of the whole numbers or natural numbers. This is because
set of whole numbers = {0,1,2,3,4,5,...}
set of natural numbers = {1,2,3,4,5,...}
The only difference is that 0 is not included in the set of natural numbers. Neither set has negative values in them.
So for instance the set {-5, 1,2,7} involves a number that is neither part of the whole numbers or natural numbers set. But every item listed is an integer
set of integers = { ..., -3, -2, -1, 0, 1, 2, 3, ... }
We can see that the integers is the set of positive and negative whole numbers, with 0 as well
Answer:
All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

1. Explain how you can use the algebraic representation to determine the new coordinates of a point.
Answer:
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
Step-by-step explanation:
In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.
To find out the coordinates of a point in the coordinate system, follow the following procedure.
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
The x-coordinate and the y-coordinate determine the new coordinates of a point.
Jayden deposited $13 in a savings account that earns 2.6% simple interest. Which graph represents this scenario?
Answer:
not a hundred percent sure since there are no graphs attached but mine was Graph 1 to be the answer
After 2 years she will have earned $12 * 2*2.3% = $12* 4.6% = 55c interest (to the nearest cent). Therefore the balance will be $12.55
After 6 years she will have earned $12 * 6*2.3% = $12* 13.8% = $1.66 interest (to the nearest cent).
Therefore the balance will be $13.66
After 10 years she will have earned $12 * 10*2.3% = $12* 23% = $2.76 interest (to the nearest cent).
Therefore the balance will be $14.76

Answer:
The minimum thickness of the book is 53.8mm
Step-by-step explanation:
Given units/terms
400 pagesFront and back - 0.9mmEach page - 0.13mmSolution:
(0.9mm)(2) + (0.13mm)(400) = 1.8 mm + 52.mm = 53.8mm
Answer:
min. thickness of the book is 53.8mm
Step-by-step explanation:
400 pages, each page thickness = 0.13mm
front and back cover thickness = 0.9mm
total thickness of the book = front + 400 pages + back cover
total = 0.9 + (400 x 0.13) + 0.9
total = 0.9 + 52 + 0.9
total = 53.8 mm

Do you think Donald Trump..... Please answer the question from the picture
Answer:
For the first it is dilation by a scale factor of 1.5. For the second it is 6. I think, sorry if they are incorrect.
Step-by-step explanation:
Ajar contains 6 pennies, 14 nickels, 16 dimes and 4 quarters. If one coin is
chosen at random, find P(nickel or dime) as a simplified fraction. You may
use the standard keyboard or Equatio to type the fraction. *
Answer:
P(nickel or dime) = 3/4
Step-by-step explanation:
First, find the total amount of coins that there are:
6 + 14 + 16 + 4 = (20) + (20) = 40
You are trying to find P(nickel or dime). Note that there are 14 nickels, and 16 dimes. Add these two numbers together:
P(Nickel or dime) = (14 + 16)/40
P(Nickel or dime) = (30)/40
Simplify. Divide common factors from both the numerator & denominator (10)
P(Nickel or dime) = (30/40)/(10/10) = 3/4
P(nickel or dime) = 3/4

Is it possible to draw a triangle with these measurements?
• Side lengths 2 cm, 3 cm, and 4 cm
Answer:
Yes
Step-by-step explanation:
To form a triangle, any 2 of the side lengths added together must be greater than the 3rd side. In this case 2cm + 3cm = 5cm which is greater than 4cm (the remaining side)

4.61 gallons of milk is sold for $14.86. If you have $21.32 in your wallet. How many
gallons of milk you can buy?
Answer:
You can buy approximately 6.6 gallons of milk.
Step-by-step explanation:
We can solve this problem by making a proportion:
4.61 gallons/$14.86 = x gallons/$21.32
By cross-multiplying, we get:
4.61 × 21.32 = 14.86x
98.29 = 14.86x
x = 6.6 gallons
(9h+3)(−h−1) porfavor ayudenme con esta pregunta.
Answer:
-9h² - 12h - 3
Step-by-step explanation:
Follow the FOIL method:
FOIL = First, Outside, Inside, Last
Multiply the terms together:
First: 9h * -h = -9h²
Outside: 9h * -1 = -9h
Inside: 3 * -h = -3h
Last: 3 * -1 = -3
Combine like terms: 9h² + (-9h - 3h) - 3
9h² - 12h - 3
-9h² - 12h - 3 is your answer.

Answer:
they get 8.27$ back.
Step-by-step explanation:
Cost of lunch=$7.29+$8.45+$5.99
=$21.73
3 of them put $10 each=$10×3
$30
Total change they got back=$30-$21.73
=$8.27

simplify 4+3(7+4 x 2)-100
Answer:
- 51
Step-by-step explanation:
Order of operations. What's in the parenthesis is first.
4 + 3 ( 7+4 x 2) - 100
Concentrate on (7 + 4 x 2 ) first.
We multiply first so 4 x 2 = 8 then we add.
(7 + 8) = 15
4 + 3(15) - 100 Again, we multiply first.
4 + 45 - 100 Now we can add and subtract in any order.
49 - 100 = - 51
Sally identified the terms of the expression 9a + 4b - 18 as 9, 4, and 18. Explain her error.
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
So the terms are 9a, 4b, and 18.
hope it helps!
Answer:
Step-by-step explanation:
For the terms of the expression , Sally has to write coefficients with the variables
Terms: 9a , 4b , - 18
coefficient of b is = 1
Coefficient of a term is the numerical value of the variable

Which is an accurate conclution regarding the system of equations below ? Y=2/3x-1 and Y=3-2/3x
Answer:
Lets start with the given system of linear equations In order to solve for one variable, we must eliminate the other variable. So if we wanted to solve for y, we would have to eliminate x (or vice versa). So lets eliminate x. In order to do that, we need to have both x coefficients that are equal but have opposite signs (for instance 2 and -2 ...
