[tex]6\frac{2}{3} = \frac{3(6) + 2}{3} = \frac{20}{3} miles[/tex]

[tex]1\frac{1}{3} = \frac{3(1) + 1}{3} = \frac{4}{3} miles/day[/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]

= [tex]\frac{20(3) days}{3(4)} = \frac{20 days}{4} = 5 days[/tex]

Answer: 5 days

This problem can be solved using proprtions.  Once you set up the proportion, the calculations are easy.

Let x = number of pens made in 1 second.

[tex]\frac{9pen}{3sec} = \frac{xpen}{1 second}[/tex]

Now, you just cross multiply and solve.

9 = 3x

x = 3

The rate is 3 pens per second.

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 formula of a midpoint:

[tex]M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)[/tex]

Substitute:

[tex]\dfrac{-2+x_B}{2}=-6\qquad|\cdot2\\\\-2+x_B=-12\qquad|+2\\\\x_B=-10\\\\\dfrac{10+y_B}{2}=8\qquad|\cdot2\\\\10+y_B=16\qquad|-10\\\\y_B=6[/tex]

Answer:

7/4  or 3

Step-by-step explanation:

To determine the slope of the line , we look at the position of the line

From the given graph , the line goes up

When line goes up , the slope is positive

when a line goes down , the slope is negative

If we have a vertical line then slope is undefined

For horizontal line the slope is 0

Here the line goes up, so slope is positive

We pick the slope from the given option that is positive

7/4  or 3

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.

I hope this helps! Have a day as sweet and fresh as lemonade! :)

The answer is ( m=15 )

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]

We can find the maximum number of CDs she can buy by dividing 153 by 18. The answer ends up being 8.5. Since she can't buy 0.5 of a CD, she can buy a maximum of 8 CDs. Written as an inequality, I think it should be x is less than or equal to 8. I hope this helps!

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.

Step-by-step explanation:

n = -4/9 hope this helps

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

-9n=4

n=4/-9

n=-4/9

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

6396÷15=426.4

15 will go into 63 4 times with 3 left

bring down the 9 now you have 39 and 15 will go into it 2 times with 9 left

bring down the 6 you have 96 and 15 will go into that 6 times with 6 left

put you decimal after the 6 and bring down a 0

60 ÷ 15 =4

0 remainder

Answer:

-1 1/4

Step-by-step explanation:

Do it in pieces. Everything is divisible by 3, so you can do it in your head.

... (-3 3/4)/3 = (-3/3) -(3/4)*(1/3) . . . . . an integer part divisible by 3, and a fraction divisible by 3

... = -1 -(3*1)/(3*4) . . . . factors of 3 cancel

... = -1 -1/4

... = -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.

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

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.

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]
