−2x − 10 = 15 I'm really un smart

Answers

Answer 1

Answer:

x = -12.5

Step-by-step explanation:

your goal is to get x alone so

-2x - 10 = 15

(add ten to both sides)

-2x = 25

(divide -2 to both sides)

x = -12.5

remember that whatever u do to one side of the equation, you have to do to the other so they even out!

Answers

Answer:

x=18

Step-by-step explanation:

Vertical angles mean that the angles are the same, diagonal from each other.

So, you can assume that <1=<3,

4x-14=58

Solve this as an equation

58+14=72

72/4=18

x=18

So because they are Vertical angles, they are equal! The equation would be (4x-14)=58. When you solve for that, you get x=18

Answer:

2x = 6

Step-by-step explanation:

Simplify the following algebraic expressions.

- 6x + 5 + 12x -6

2(x - 9) + 6(-x + 2) + 4x

3x2 + 12 + 9x - 20 + 6x2 - x

(x + 2)(x + 4) + (x + 5)(-x - 1)

1.2(x - 9) - 2.3(x + 4)

(x2y)(xy2)

(-x2y2)(xy2)

Solution

Group like terms and simplify.

- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)

= 6x - 1

Expand brackets.

2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x

Group like terms and simplify.

= (2x - 6x + 4x) + (- 18 + 12) = - 6

Group like terms and simplify.

3x2 + 12 + 9x - 20 + 6x2 - x

= (3x2 + 6x2) + (9x - x) + (12 - 20)

= 9x2 + 8x - 8

Expand brackets.

(x + 2)(x + 4) + (x + 5)(- x - 1)

= x2 + 4x + 2x + 8 - x2 - x - 5x - 5

Group like terms.

= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)

= 3

Expand and group.

1.2(x - 9) - 2.3(x + 4)

= 1.2x - 10.8 - 2.3x - 9.2

= -1.1x - 20

Rewrite as follows.

(x2y)(xy2) = (x2 x)(y y2)

Use rules of exponential.

= x3 y3

Rewrite expression as follows.

(-x2y2)(xy2) = -(x2 x)( y2 y2)

Use rules of exponential.

= - x3 y4

Simplify the expressions.

(a b2)(a3 b) / (a2 b3)

(21 x5) / (3 x4)

(6 x4)(4 y2) / [ (3 x2)(16 y) ]

(4x - 12) / 4

(-5x - 10) / (x + 2)

(x2 - 4x - 12) / (x2 - 2 x - 24)

Solution

Use rules of exponential to simplify the numerator first.

(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)

Rewrite as follows.

(a4 / a2) (b3 / b3)

Use rule of quotient of exponentials to simplify.

= a2

Rewrite as follows.

(21 x5) / (3 x4) = (21 / 3)(x5 / x4)

Simplify.

= 7 x

(6 x4)(4 y2) / [ (3 x2)(16 y) ]

Multiply terms in numerator and denominator and simplify.

(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)

Rewrite as follows.

= (24 / 48)(x4 / x2)(y2 / y)

Simplify.

= (1 / 2) x2 y

Factor 4 out in the numerator.

(4x - 12) / 4 = 4(x - 3) / 4

Simplify.

= x - 3

Factor -5 out in the numerator.

(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)

Simplify.

= - 5

Factor numerator and denominator as follows.

(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]

Simplify.

= (x + 2) / (x + 4) , for all x not equal to 6

Solve for x the following linear equations.

2x = 6

Tell which property is being illustrated: 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7

Commutative Property of Addition
or
Additive Identity Property of 0.



Tell which property is being illustrated: 16 + 0 =16

Additive Identity Property of 0
or
Commutative Property of Addition

Answers

Answer:

Hi! For the first question, the property being demonstrated is the Commutative Property of Addition. For the second problem, the answer would be the Additive Identity Property of 0.

Step-by-step explanation:

In the problem 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7, we can see the commutative property being used. The Commutative Property of Addition states that changing the order of the addends will not have an affect on the sum. As long as you still keep the same addends, the sum will always remain the same regardless of the order.

In the problem 16 + 0 = 16, we see the Additive property of 0 being demonstrated. This property basically states that adding a number to 0 will give you the same number. It is usually very easy to identify if you look for 0 being added to an addend.

Ill give 100 points to whoever gives me the CORRECT answer. I keep getting syntax errors when I do the "add:" part. Can someone walk me through this code?Part A One of the biggest benefits of writing code inside functions is that we can reuse the code. We simply call it whenever we need it! Lets take a look at a calculator program that could be rewritten in a more reusable way with functions. Notice that two floats (decimal numbers, but they can also include integers) are inputted by the user, as an operation that the user would like to do. A series of if statements are used to determine what operation the user has chosen, and then, the answer is printed inside a formatted print statement. num1 = float(input("Enter your first number: ")) num2 = float(input("Enter your second number: ")) operation = input("What operation would you like to do? Type add, subtract, multiply, or divide.") if operation == "add": print(num1, "+", num2,"=", num1 + num2) elif operation == "subtract": print(num1, "-", num2,"=", num1 - num2) elif operation == "multiply": print(num1, "*", num2,"=", num1 * num2) elif operation == "divide": print(num1, "/", num2,"=", num1 / num2) else: print("Not a valid operation.") Your job is to rewrite the program using functions. We have already looked at a function that adds two numbers. Using that as a starting point, we could call the add function from within our program in this way: if operation == add: result = add(num1, num2) print(num1, "+", num2,"=",result) Now its your turn to do the following: Type all of the original code into a new file in REPL.it. Copy the add function from the unit and paste it at the top of your program. Write 3 additional functions: subtract, multiply, and divide. Pay careful attention to the parameters and return statement. Remember to put the three functions at the top of your Python program before your main code. Rewrite the main code so that your functions are called. Part B There are many different ways that a user could tell us that he or she would like to add two numbers in our calculator program. The user could type add, Add, ADD, or +, to name a few possibilities.
