Answer:

First, collect the like terms

3x+2x=180+11-5

Solve for x

5x=191-5

5x=186

x=186/5=37.2

Step-by-step explanation:

I hope it helped a little, please give me brainliest

Answer:

x = 37.2

see first you've got to remove terms without the pronumeral to the other side of the equal to.

Answer:

-3/9

Step-by-step explanation:

The equation would be: x * 9 + 5 = 2

Subtract 5 from each side: x * 9 = -3

Divide each side by 9: x = -3/9

Answer:

Swimming speed, S = 1.50 km/hr

Step-by-step explanation:

Let Kailee's running speed be R

Let Kailee's biking speed be B

Let Kailee's swimming speed be S

Given the following data;

Time for swimming = 1 hour.

Time for biking = 1.75 hour.

Time for running = 1 hour.

Total distance = 55.5km

Translating the word problem into an algebraic equation, we have;

Biking speed = 2*8S = 16S

Running speed = 8S

We know that the distance covered by an object or body is given by the formula;

[tex] Distance = speed * time[/tex]

Now we would find the distance covered in each activity (biking, running and swimming).

For biking;

[tex] Distance, D_{1} = 1.75*16S [/tex]

Distance, [tex] D_{1} [/tex] = 28S

For running;

[tex] Distance, D_{2} = 1*8S[/tex]

Distance, [tex] D_{2} [/tex] = 8S

For swimming;

[tex] Distance, D_{3} = 1*S[/tex]

Distance, [tex] D_{3} [/tex] = S

The equation for the total distance covered in the triathlon is given by;

Total distance = sum of all distances covered

[tex] Total distance = D_{1} + D_{2} + D_{3} [/tex]

Substituting into the equation, we have;

[tex] 55.5 = 28S + 8S + S[/tex]

[tex] 55.5 = 37S[/tex]

[tex] S = \frac {55.5}{37} [/tex]

S = 1.50 km/hr

Therefore, Kailee’s average swimming speed is 1.50 kilometers per hour.

How to Simplify a Ratio A : B when A and B are both whole numbers

List the factors of A

List the factors of B

Find the greatest common factor of A and B, GCF(A, B)

Divide A and B each by the GCF

Use the whole number results to rewrite the ratio in simplest form

If the GCF = 1 then the ratio is already in simplest form.

How to Simplify a Ratio A : B when A and B are not whole numbers, in this order

If A or B are mixed numbers convert mixed numbers to improper fractions

If A or B are decimal numbers multiply both values by the same factor of 10 that will eliminate all decimal places

If one value is a fraction and the other a whole number, reduce the fraction to a whole number if you can or turn the whole number into a fraction by giving it a denominator of 1.

If both A and B are fractions and have like denominators, multiply both fractions by the denominator to eliminate it and you are left with two whole numbers

If both A and B are fractions and have unlike denominators, find the LCD(A, B) and rewrite the fractions with the LCD as the denominator. Multiply both fractions by the denominator to eliminate it and you are left with two whole numbers

If both A and B are whole numbers, Find the greatest common factor of A and B, GCF(A, B), and divide A and B each by the GCF

Example: Simplify the ratio 6 : 10

The factors of 6 are: 1, 2, 3, 6

The factors of 10 are: 1, 2, 5, 10

Then the greatest common factor of 6 and 10 is 2

Divide both terms by 2

6 ÷ 2 = 3

10 ÷ 2 = 5

Rewrite the ratio using the results. The simplified ratio is 3 : 5.

6 : 10 = 3 : 5 in simplest form

Answer:

List the factors of A.

List the factors of B.

Find the greatest common factor of A and B, GCF(A, B)

Divide A and B each by the GCF.

Use the whole number results to rewrite the ratio in the simplest form.

Answer:

8+2i

Step-by-step explanation:

Combine like terms

3+5=8

4i-2i=2i

Answer: 8 + 2i

Step-by-step explanation:

1) Rewrite the two complex numbers in standard form: (3 + 4i) + (5 − 2i) = 3 + 5 + 4i - 2i = 3 + 5 + 2i

2) Add the real parts and the imaginary parts separately: Real parts: 3 + 5 = 8 Imaginary parts: 2i + (-2i) = 0

3) Put the results in standard form: 8 + 0i = 8 + 0i = 8 + 0i = 8 + 0i = 8 + 0i = 8 + 2i

Answer:

$11.65

Step-by-step explanation:

20% of 58.25, "of" in math means multiplication. So you multiply it.

To get 20% as a fraction you move the decimal 2 places to the left, and it's .2 or .20 so you get this equation:

.20 * 58.25

So your answer is, $11.65.

To find the total of the bill including the tip it would just be

11.65 + 58.25 = 69.90

Answer: If it is 4-x, then the answer is b, no solution. If it is 4x, then it is a, one solution.

Answer:

17 hours

Step-by-step explanation:

Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?

The illustration can be modelled using the equation

y = 10 + 1(x)

y = 10 + x

Where,

y = total number of pages

x = number of hours

10 = pages already written

If y = 27 pages, find x

y = 10 + x

27 = 10 + x

27 - 10 = x

17 = x

x = 17 hours

Rachel have to spend 17 hours writing this week in order to have written a total of 27pages

Answer:

540°

Step-by-step explanation:

When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°

A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...

180 x 3 = 540

Answer:

Step-by-step explanation:

[tex]sec A=\frac{14}{\sqrt{171} } \\cos ~A=\frac{\sqrt{171} }{14} \\sin ~A=\sqrt{1-cos^2A} =\sqrt{1-\frac{171}{196} } =\sqrt{\frac{196-171}{196} } =\sqrt{\frac{25}{96} } =\pm\frac{5}{14} \\csc A=\pm \frac{14}{5}[/tex]

as A is in quadrant 1

[tex]so~csc~A=\frac{14}{5}[/tex]

in quadrant 1 both sin A and csc A are positive.

Answer:

Step-by-step explanation:

The page is 16 -5 = 11 inches wider than the photo, so the margin on either side needs to be 11/2 = 5 1/2 inches.

The translation of the given question is

f (x) = - 8x− 4 what is the slope y and the position coefficient f (x) = (6x− 12): 3 what is the slope y and the position coefficient

Answer:

We need to determine slope and position coefficient which is the intercept.

f (x) = - 8x− 4   we know that f(x) is y

slope intercept form of the line

y = -8x -4

slope = -8

intercept = -4

similarly

f (x) = 6x− 12

y = 6x -12

slope =6

intercept = -12

Answer:

The answer is C, the slope is 4.

Step-by-step explanation:

Finding slope using two given points is easy. You need to do (y2-y1/x2-x1)

(-1,-4) the -1 is x1 and the -4 is y1. (-3,4) the -3 is x2 and the 4 is y2.

You plug them into the formula giving you

(4-(-4)/ -3-(-1)= 8/-2= 4

Answer:

85

Step-by-step explanation:

The range is defined as the difference between the highest observation and lower observation in a data.

Here,

The Highest observation in this data= 91

The Lowest observation in this data=6

Hence,

Range of the data= Highest observation - Lower observation

=91-6=85
