The algebraic property of "if 12+4x then 4x+12" is: commutative property of addition.

The Commutative Property of Addition is an algebraic property that states that the change of arrangement or order of an expression does not change the sum of the expression.

For example, based on the commutative property of addition, a + b = b + a.

In the same vein, if we have 12 + 4x, then 4x + 12, it means that whichever way we choose to order the operation, the sum remains the same.

Therefore, the algebraic property of "if 12+4x then 4x+12" is: commutative property of addition.

Answer:

If you roll two dices, you can get as results all numbers from 2 to 12. Among these, the prime numbers are 2, 3, 5, 7, 11. The probability you get each of them is: 2: you can get it only as 1+1, so one combination over 36 possibility. Probability: 1/36. 3: you can get it as 1+2 or 2+1, so two combinations over 36 possibility. Probability: 2/36. 5: you can get it as 1+4, 2+3, 3+2, 4+1, so four combinations over 36 possibility. Probability: 4/36. 7: you can get as 1+6, 2+5, 3+4, 4+3, 5+2, 6+1, so six combinations over 36 possibility. Probability: 6/36. 11: you can get it as 5+6 or 6+5 so two combinations over 36 possibility. Probability: 2/36. The total probability of getting a prime number is the sum of the probabilities, which is 15/36. So m=15, n=36 and 10m+n=150+36=186.

Step-by-step explanation:

the derivative of the sum of terms in x is the same as the sum of the derivatives of the individual terms.

d/dx × (-4sin(x) + 9x) = d/dx × (-4sin(x)) + d/dx × (9x)

and also : the derivative of a term in x multiplied by a constant c is c × derivative of the term in x.

d/dx × (-4sin(x)) + d/dx × (9x) =

-4 × (d/dx × sin(x)) + 9 × (d/dx × x)

so, what is the derivative of sin(x) ? cos(x)

what is the derivative of x ? 1

so, we have as result :

-4cos(x) + 9

Answer:

Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75

Step-by-step explanation:

Let,

x be the cost of each apple pie

y be the cost of each lemon merigue pie

According to given statement;

5x+2y=80     Eqn 1

3x+6y=90     Eqn 2

Multiplying Eqn 1 by 3

3(5x+2y=80)

15x+6y=240    Eqn 3

Subtracting Eqn 2 from Eqn 3

(15x+6y)-(3x+6y)=240-90

15x+6y-3x-6y=150

12x=150

Dividing both sides by 12

[tex]\frac{12x}{12}=\frac{150}{12}\\x=12.50[/tex]

Putting x=12.50 in Eqn 1

5(12.50)+2y=80

62.50+2y=80

2y=80-62.50

2y=17.50

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{17.50}{2}\\y=8.75[/tex]

Hence,

Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75

The cost of one taco is $3.75.

We are given cost of salad, the sales tax and tip along with total expenditure. We already know, that sales tax is calculated on the cost of items. Hence, forming the equation accordingly. Let us assumed the cost of one taco be $x. So, the cost of two tacos will be $2x.

The equation will be -

2x + 2.50 + (2x + 2.50)×(6÷100) + 3 = 13.60

2x + 2.50 + (2x + 2.50)×0.06 + 3 = 13.60

Now, solving this equation to find the value of x and hence the cost of one taco.

2x + 2.50 + 0.12x + 0.15 + 3 = 13.60

Performing addition on Left Hand Side

2.12x + 5.65 = 13.60

Shifting 0.18 to Right Hand Side and performing subtraction

2.12x = 13.60 - 5.65

2.12x = 7.95

x = 7.95÷2.12

Performing division

x = 3.75

Thus, the cost of one taco is $3.75.

Answer:

All of them except for the 3rd one

Step-by-step explanation:

2) 15 - 3x = 5(x + 4) - 8x

15 - 3x = 5x + 20 - 8x

15 - 3x ≠ -3x + 20

4) 2(x - 7) = 2x - 10

2x - 14 ≠ 2x - 10

1) 24x - 22 = -4(1 - 6x)

24x - 22 ≠ -4 + 24x

3) 12 - 2x = 6(2x + 2)

12 - 2x = 12x + 12

0 = 14x

0 = x, only one that has a solution

The solutions for x are x < 16 and x < 7/ 3 respectively

The absolute value of a real number can be defined as the non-negative value of that number without regard or consideration to its sign.

It is also described as the modulus of a number.

Given the inequality;

||x+4|-7|<5

Take the absolute value

x + 4 + 7 < 5

collect like terms

x < 5 + 4 + 7

Add like terms

x < 16

||3x-1|+5|<1

Take the absolute value

3x + 1 + 5 < 1

collect like terms

3x < 1 + 5 + 1

3x < 7

Make 'x' the subject

x < 7/ 3

Thus, the solutions for x are x < 16 and x < 7/ 3 respectively.

Answer:

The value of b is 5 times the value of a.

Step-by-step explanation:

The rule that describes the pattern in the table is that the value of b is 5 times the value of a.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The table shows two sets of values, a and b, where b is obtained by multiplying a by 5.

For example, when a = 1, b = 5, and when a = 2, b = 10.

This pattern continues throughout the table.

Therefore,

The rule that describes the pattern in the table is that the value of b is 5 times the value of a.

Answer:

x =-18

Step-by-step explanation:

5(x + 9) = -45

Divide each side by 5

5/5(x + 9) = -45/5

Subtract 9 from each side

x+9-9 = -9 -9

x =-18

Answer:

The correct answer is x = -1.

Step-by-step explanation:

Step 1: 5(x + 9) = -45 <----- This is the original problem.

Step 2: 5(9x) = -45 <----- Add the variable.

Step 3: [tex]\frac{5(9x)}{5} = \frac{-45}{5}[/tex] <----- Divide both sides by 5.

Step-by-step explanation:

The correct equation to find 40 percent of 25 is: D. Start Fraction 40 divided by 4 Over 100 divided by 4 End Fraction = Start Fraction 10 Over 25 End Fraction

Let's go through each option and determine the correct equation step by step.

A. Start Fraction 25 divided by 1 Over 40 divided by 1 End Fraction = Start Fraction 25 Over 40 End Fraction

This equation represents the division of 25 by 40. However, we want to find 40 percent of 25, not divide 25 by 40. So, this equation is not the correct one.

B. Start Fraction 100 times 4 Over 40 times 4 End Fraction = Start Fraction 400 Over 16 End Fraction

In this equation, we multiply 100 by 4 and divide it by 40 multiplied by 4. Simplifying this expression, we get 400 divided by 16, which is equal to 25. This equation does not give us the value of 40 percent of 25, so it is not the correct one.

C. Start Fraction 40 times 4 Over 25 times 4 End Fraction = Start Fraction 160 Over 100 End Fraction

Here, we multiply 40 by 4 and divide it by 25 multiplied by 4. Simplifying this expression, we get 160 divided by 100, which is equal to 1.6. This equation does not give us the value of 40 percent of 25, so it is also not the correct one.

D. Start Fraction 40 divided by 4 Over 100 divided by 4 End Fraction = Start Fraction 10 Over 25 End Fraction

In this equation, we divide 40 by 4 and divide 100 by 4. Simplifying this expression, we get 10 divided by 25, which is equal to 0.4. This equation represents 40 percent of 25, as 0.4 is equal to 40 percent when expressed as a decimal. Therefore, the correct equation is D.

The slope is rise over run.

The rise is how much it went up and the run is how much it went right
