n-2=10n+4/2

We move all terms to the left:

n-2-(10n+4/2)=0

We add all the numbers together, and all the variables

n-(10n+2)-2=0

We get rid of parentheses

n-10n-2-2=0

We add all the numbers together, and all the variables

-9n-4=0

We move all terms containing n to the left, all other terms to the right

Answer: 1/2.

Explanation:

First, note that since the previous drops have already happened, their result do not modify the occurrence of future results when the toast is dropped again.

In oder to have a total of three time landing butter side up, exactly, there are two possibilities:

Since there are two ways of totaling side up 3 times, you have to sum both chances.

1) Next drop butter side up and second drop butter side down:

     1/2 × 1/2  = 1/4

2) Next drop butter side down and second one butter side up:

     1/2 × 1/2 = 1/4

3) Add both probabilities: 1/4 + 1/4 = 1/2

And that is the answer: 1/2

Calculate f(3) by replacing X with 3:

f(x) = x^2 -1

f(3) = 3^2 -1

F(3) = 9-1

f(3) = 8

Now calculate f(-4) by replacing x with -4:

f(x) = x^2 -1

f(-4) = (-4)^2 - 1

f(-4) = 16 -1

f(-4) = 15

Now add f(3) to f(-4)

8 + 15 = 23

The answer is a) 23

The answer would be the 126th person

We have to find what would be divisible to 7 and 18.

Trying to divide 126 by 7 and 18 (different problems) would get the answer

:)

The 126th person will be the first to get both coupons.

Explanation: The lowest common factor of 7 and 18 is 126 (which means the number that 7 and 18 multiply into.)

The area of the park is 2.45 acres.

The area of a park is determined to be exactly halfway between 2.4 acres and 2.5 acres. To find this midpoint or average, we add the two values together and then divide by 2.

First, we add 2.4 acres and 2.5 acres:

2.4 acres + 2.5 acres = 4.9 acres

Now, we divide this sum by 2 to find the midpoint:

Midpoint = 4.9 acres / 2 = 2.45 acres

Therefore, the area of the park is 2.45 acres. This means that it is precisely halfway between the two given values.

Understanding the midpoint or average is essential in various contexts, such as real estate, land measurement, and statistical analysis. In this case, it signifies that the park occupies an area that is equidistant from 2.4 acres and 2.5 acres. It can be seen as a balanced point between these two values, serving as a useful concept for situations where precision or fairness is required, such as in property assessments or distributing resources evenly.

y+6=1/3(x-9)

Moved all terms from left to right that doesn't contain y

Y=-6 +1/3x-3

Simplify

Y=1/3x-9

Your answer is c.

Answer: [tex]y=\dfrac{1}{3}x-9[/tex]

Step-by-step explanation:

The equation of a line in slope -intercept form is written as :-

[tex]y=mx+c[/tex]

The given equation : [tex]y+6=\dfrac{1}{3}(x-9)[/tex]

To write the given equation in slope - intercept form , we need to first solve the right -hand sides in the equation.

[tex]y+6=\dfrac{1}{3}(x-9)\\\\\Rightarrow\  [tex]y+6=\dfrac{1}{3}x-3\\\\\Rightarrow\ y=\dfrac{1}{3}x-3-6\\\\\Rightarrow\ y=\dfrac{1}{3}x-9[/tex]

Hence, the equation written in slope-intercept form :  [tex]y=\dfrac{1}{3}x-9[/tex]

76x+608-2=13

76x+606=13

76x= -593

x= -7.8

How to get answer:

Step 1: Simplify both sides of the equation.

38(2x+16)−2=13

(38)(2x)+(38)(16)+−2=13(Distribute)

76x+608+−2=13

(76x)+(608+−2)=13(Combine Like Terms)

76x+606=13

76x+606=13

Step 2: Subtract 606 from both sides.

76x+606−606=13−606

76x=−593

Step 3: Divide both sides by 76.

Let

x---------> the number of child tickets

y--------> the number of adult tickets

we know that

the equation that describes the relationship between the number of child tickets and the number of adult tickets  is a linear equation

If the point[tex](4,2)[/tex] is the solution

then

the number of child tickets is [tex]4[/tex]

the number of adult tickets is [tex]2[/tex]

therefore

the answer is

the  solution [tex](4,2)[/tex] represent that

the number of child tickets is [tex]4[/tex]

the number of adult tickets is [tex]2[/tex]

The solution (4, 2) means Olivia purchased 4 child tickets and 2 adult tickets at the movies for a total of $46.

The student's question involves interpreting the solution to a linear equation in the context of purchasing movie tickets. The specific solution given is the ordered pair (4, 2). In the context of the problem described, the number '4' represents the quantity 'x', which is the number of child tickets purchased, and the number '2' represents the quantity 'y', which is the number of adult tickets purchased. Therefore, the solution (4, 2) means that Olivia purchased 4 child tickets and 2 adult tickets at the movies for a total expenditure of $46.

Hey there! Welcome to Brainly

We see that Damian earns $8 for every hour he works. This means that when x=1, Damian will earn 8 dollars, 2 he will earn $16, etc.

Since he constantly adds 8 every hour, it would look like this.

8+8+8+8+8+8+8.....

This is an example of multiplication.

The thing is, we are not sure how many 8's we are adding.

We can use the variable "x" to represent ANY number of 8's, or hours he worked.

We would multiply this x by 8 to show that he will earn $8 for EACH number of hours he works.

8 x x

The problem is, we cannot write our multiplication sign like this, because it looks just like our x we are using.

We can rewrite our multiplication symbol using · or we can just put our x right next to the eight. When a variable is right next to a constant, or number without a variable, it turns it into a mini multiplication equation, but in a simplified form.

8x

Now, we need to write this as an equation. We need to say that something else is equal to 8x. We could say, his money, which we can represent with as d.

Therefore, we could write our equation as d= 8x.

Answer:

s can take any real value.

Step-by-step explanation:

Given that

-2(6+s)_>-15-2s

Distribute -2 over 6+s

-12-2s >= -15-2s

Simplify both the sides

Add 2s to both the sides.

We get 2s cancel out and -12>=-15 which is true.

Hence the given inequality is valid for all values of s.

This is a special case of inequality which has infinite number of solutions.

s can take any real number and this inequality is valid.

Answer:

Solution of inequality: -12 ≥ -15 Which is true.

Step-by-step explanation:

Given data:

Equation:-2(6+s)_>-15-2s

-2(6+s)_>-15-2s

=-12 - 2s ≥ - 15 -2s

By dividing -2s on both sides:

= -12 - 2s/-2s ≥ - 15 -2s/-2s

= -12 ≥ -15

                                                  -2(6+s)_>-15-2s =  -12 ≥ -15

The answer is ( m=15 )

5 1/2 + 12 (1 1/4)

It really does help to play with blocks, Legos, chips, coins, rocks, or counters of any kind. Arrange them, deal them into piles, put them is rectangles or triangles (and be aware of how many you use). It also helps to cook from recipes that require use of fractional measures. The cups and spoons give you a sense of what size fractions are larger/smaller, and how they are related. Appropriate play with counting and arranging and measuring can help you develop your number sense, and help you learn to do problems like this in your head.

Step-by-step explanation:

For m it’s 1,1/3and -5/3 you will get different values when plug the different values of n

For this case we have:

m represents the total cost of each meal. If people do not pay a tip, the total cost to pay would be:

[tex]m + m + m = 3m\\[/tex]

Person 1:

Without tip the cost of your meal is m.

You want to pay 10% tip

m -------------------> 100%

x --------------------> 10%

[tex]x =\frac{(10)(m)}{100} = 0.1m\\[/tex]

Thus, its cost will be:

[tex]C1 = m + 0.1m = 1.1m\\[/tex]

Person 2:

Without tip the cost of your meal is m.

m -------------------> 100%

x --------------------> 15%

[tex]x =\frac{(15)(m)}{100} = 0.15m\\[/tex]

Thus, its cost will be:

[tex]C2 = m + 0.15m = 1.15m\\[/tex]

Person 3:

Without tip the cost of your meal is m.

m -------------------> 100%

x --------------------> 20%

[tex]x =\frac{(20)(m)}{100} = 0.20m\\[/tex]

Thus, its cost will be:

[tex]C3 = m + 0.20m = 1.20m\\[/tex]

Thus, the total cost to pay will be:

[tex]C = 1.1m + 1.15m + 1.20m\\[/tex]

Answer:

[tex]C = 1.1m + 1.15m + 1.20m[/tex]

[tex]\frac{20}{3} miles[/tex] ÷ [tex]\frac{4}{3} miles/day[/tex]

= [tex]\frac{20(miles)}{3}[/tex] * [tex]\frac{3(days)}{4 (miles)}[/tex]
