Solve for x in the equation below(all in picture).

Answer:

n = 4

Step-by-step explanation:

We can expand, getting 10 + 5n = 3n + 18.

Then, combine all like terms, getting 5n - 3n = 18 - 10, which can be rewritten as 2n = 8.

Solve this by dividing both sides by 2, and get n = 4.

Answer: so its n=4

Step-by-step explanation:   This problem will require distribution

5(2+n) = 3(n+6)

10+5n=3n+18

Move all the variables on one side

5n-3n=18-10

2n=8

Divide by 2

n=4

5 ( 2 + n ) = 3 ( n + 6 )

First distribute the 5 and the 3. By doing that, your equation should look like

10 + 5n = 3n + 18 Now, subtract 3n from both sides, this way all the " n " would be on the same side making it easier to solve

By subtracting 3n from both sides the equation would be

10 + 2n = 18 Now subtract 10 from both sides

By subtracting 10 from both sides your equation should be

2n = 8 Divide 2 from both sides

By dividing your equation should look like

n = 4 which is your answer

Answer:

3x² + 10x + 5

Step-by-step explanation:

Sum the sides together for perimeter (P)

Starting with the base and going clockwise

P = x² + 5x - 2 + x² + 5 + x² + 1 + 4 + 3x - 3 + 2x ← collect like terms

  = 3x² + 10x + 5

Answer:

8 books

Step-by-step explanation:

Earning for each ticket is $0.25 and for each book is $2

If total earning for 4 tickets and x books is $17, then the equation is:

So Molly purchased 8 books

Answer:

The total of people is the 100%.

68% owns a tv.

72% owns radios.

12% does not own anything.

Now, if we add those, we have:

12% + 68% + 72% = 152%.

This is larger than the 100%, then this means that there is a percentage of people that have both Tv and Radio, this percentage is:

152% - 100% = 52%

We have a surpass because we are adding those 52% two times (because they belong in two different groups)

So, the table is:

68% owns a tv.

72% owns a radio.

12% does not own anything.

52% owns both, radio and tv.

68% - 52% = 16% owns only tv.

72% - 52% = 20% owns only radio.

Then the Venn diagram consist in two circles, one with the 72%, other with the 68%, in such way that the circles have an intersection of the 52%.

Answer:

Step-by-step explanation:

9.48 as a mixed number in simplest form:

948/100

948/100= 948 ÷ 4/100 ÷ 4

948/100= 948 ÷ 4/100 ÷ 4= 237/25

948/100= 948 ÷ 4/100 ÷ 4= 237/25= 9 12/25

9 12/25 is the mixed number.

Hi

on a regular dice you have  3 even number  :  2 ;4;6

                                                3  odd number : 1;3;5

so probability to have an odd number is : 3/6 = 1/2

Answer:

1/2

Step-by-step explanation:

On normal six-sided die, there are the numbers: 1, 2, 3, 4, 5, and 6.

The odd numbers are 1, 3, and 5.

There is a [tex]\frac{1}{6}[/tex] chance that you will roll any number specifically. Since you stated 3 numbers, the probability that you will roll any of those three numbers is [tex]\frac{3}{6}[/tex], which is equivalent to [tex]\frac{1}{2}[/tex].

Answer:

The correct option is;

x,                f(x)

-5,               3

-1,               -2

2,               -4

6,                 1

Step-by-step explanation:

The reflection of a point (x, y) across the x-axis is given by the relation;

Coordinate of the pre-image (x, y) [tex]\overset{Reflection \ across \ the \ x-axis}{\rightarrow}[/tex] Coordinate of image (x, -y)

Therefore, we have for the points as follows;

(-5, -3)  [tex]\overset{Reflection \ across \ the \ x-axis}{\rightarrow}[/tex] (-5, 3)

[tex](-5, -3) \mapsto (-5, 3)[/tex]

(-1, 2)  [tex]\overset{Reflection \ across \ the \ x-axis}{\rightarrow}[/tex] (-1, -2)

[tex](-1, 2) \mapsto (-1, -2)[/tex]

(2, 4)  [tex]\overset{Reflection \ across \ the \ x-axis}{\rightarrow}[/tex] (2, -4)

[tex](2, 4) \mapsto (2, -4)[/tex]

(6, -1)  [tex]\overset{Reflection \ across \ the \ x-axis}{\rightarrow}[/tex] (6, 1)

[tex](6, -1) \mapsto (6, 1)[/tex]

Answer:

[tex]\Large \boxed{\mathrm{27. \ 14 \ days}} \\ \\ \Large \boxed{\mathrm{29. \ 4 \frac{1}{6} \ feet}}[/tex]

Step-by-step explanation:

(27)

We can apply ratios to solve for the problem.

Let x be the missing value.

[tex]\displaystyle \frac{152}{4} =\frac{532}{x}[/tex]

Cross multiply.

152 × x = 532 × 4

152x = 2128

Divide both sides by 152.

x = 14

(29)

We can apply ratios to solve for the problem.

Let x be the missing value.

[tex]\displaystyle \frac{1}{6\frac{1}{4} } =\frac{\frac{2}{3} }{x}[/tex]

Cross multiply.

1 × x = 6 1/4 × 2/3

x = 6 1/4 × 2/3

Convert mixed fraction to improper fraction.

x = 25/4 × 2/3

x = 50/12

Simplify.

x = 25/6 or 4 1/6

Problem 1

Answer:  0-7+11 = 4

-----------------------------------

Explanation:

The bottom arrow is where we start. Specifically at 0 on the number line.

Then we move 7 units to the left. This is represented by -7 on the number line. So -7 is part of the addition equation.

Then we move 11 units to the right to arrive at 4 on the number line. This is the same as adding 11 to -7 to get -7+11 = 4 and that is the same as 0-7+11 = 4

======================================================

Problem 2

Answer:  1 + (-5) + 9 = 5

-----------------------------------

Explanation:

We now start at 1 on the number line. Move 5 units to the left to get to -4

Moving 5 units to the left is the same as subtracting 5, or adding on -5

So far we have 1 + (-5) which simplifies to -4

The last thing we do is add on 9 to go from -4 to 5. In other words, we move 9 units to the right when we go from -4 to 5

In terms of an equation,  -4 + 9 = 5

So overall, that's how I got 1 + (-5) + 9 = 5

Answer/Step-by-step explanation:

a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100

Total no. of people who smoke is given = 4 + 36 = 40

Total people surveyed = 200

% of people who smoke = [tex] \frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent [/tex]

a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100

Total no. of people who do not exercise regularly = 36 + 134 = 170

Total people surveyed = 200

% of people who smoke = [tex] \frac{170}{200}*100 = \frac{170}{2}*1 = 85percent [/tex]

Answer:

[tex]\huge\boxed{ 12\ people}[/tex]

Step-by-step explanation:

At least 6 hours means that the people took at least 6 hours and at most any number that is greater than 6. Here the greatest no. is 10.

So, the range for this will be 6-10

No. of People who sleep for 6-8 hours = 9

No. of People who sleep for 8-10 hours = 3

No. of People who sleep for 6-10 hours = 9+3

=> 12 people

Answer:

x = 9 and x = -1

Step-by-step explanation:

This equation should be written all on one line:

2(x - 4)^2 = 50

using " ^ " to denote exponentiation.

Dividing both sides by 2 yields

(x - 4)^2 = 25

We must solve for x - 4, and then for x alone:

Taking the square root of both sides, we get:

x - 4 = ±5

which yields two separate solutions:  x = 9 and x = -1

Step-by-step explanation:

Each bag of cheetos are 2 dollars. So 6 dollars for all of them. Add that by 1.50 and get 7.50 total. subtract that from ten and you get 2.50

Answer:

Step-by-step explanation:

The question lacks appropriate diagram. Find the diagram attached.

Slope is the change in coordinate of the y coordinate to the x coordinate.

Mathematically, slope m = ∆y/∆x

From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)

m = ∆y/∆x = 3/1

∆y/∆x = 3/1

y/x = 3/1

Cross multiply

y × 1 = 3 × x

y = 3x

Hence the slope of the line is y = 3x

Answer:

you need to add the picture next time :)

Step-by-step explanation:

y/x=3/1 is the first blank

y=3x is the last one
