What is the solution to this equation?
X- 15 = -6

A. x= -9
B. x = 21
C. x= -21
D. x = 9

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 ...

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.

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

two

Step-by-step explanation:

-9 and 9

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

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

Answer:

Some

Step-by-step explanation:

The answer is Some

Answer:

some

Step-by-step explanation:

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

For a 90 Degree rotation the original x value becomes the new y value and the new x value is the opposite of the original y value.

The answer would be (-6,-7)

Answer:

28

Step-by-step explanation:

y/4-4 =3 /×4

y-16 =12

y =12 +16

y=28

28/4 - 4 =3

Step-by-step explanation:

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:

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

Answer:

The minimum thickness of the book is 53.8mm

Step-by-step explanation:

Given units/terms

Solution:

(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

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.
