make b the subject ​

Answers

Answer:

b= 3a-c

Step-by-step explanation:

Solve for b.

a= 1/3(b+c)

multiplying both sides by 3.

3a= b+c

subtract c from both sides.

3a-c=b

or

b= 3a-c

Answer:

b= 3a-c

Step-by-step explanation:

Solve for b.

a= 1/3(b+c)

Multiplying both sides by 3.

3a= b+c

Subtract c from both sides.

3a-c=b

or

b= 3a-c

Sienna, Rhys, and Micah are all reading the same book for school. Sienna has read 40% as far as Rhys has, and Rhys has read 40% as far as Micah has. If Sienna has read 60 pages, how many pages has Micah read?

Answers

Based on the fact that Sienna has read 60 pages, we can infer that Micha has read 375 pages of the book.

Sienna has read 40% of what Rhys has read and that corresponds to 60 pages. The number of pages read by Rhys is therefore:

= Number of pages / Percentage read

= 60 / 40%

= 150 pages

The 150 pages read by Rhys is 40% of what Micah has read. Micah has therefore read:

= 150 / 40%

= 375 pages

In conclusion, Micah has read 375 pages.

I got so confused on this question if I could get help it would mean a lot

Answers

9514 1404 393

Answer:

  x = 3

Step-by-step explanation:

You can forget about point R. It does not have any part in this problem, except to add confusion.

The given line PQ has the same y-coordinate values for points P and Q. This means the segment is a horizontal segment. Its perpendicular bisector will be a vertical line through its midpoint.

The midpoint (M) of PQ is ...

  M = (P +Q)/2

  M = ((-2, 2) +(8, 2))/2 = (-2+8, 2+2)/2 = (6, 4)/2

  M = (3, 2)

The vertical line through a point with x-coordinate 3 will have the equation ...

by what percentage did the high temperature increase from friday to saturday ? round ur answer

Answers

Answer:

Step-by-step explanation:

First, you must find the actual decrease in temperature.

Decrease = Yesterday's temperature - Today's temperature

Decrease = 80 - 75

Decrease = 5 degrees

Now, find the percentage decrease.

% Decrease = Actual decrease / Yesterday's temperature x 100

% Decrease = 5/80 x 100

% Decrease = 0.0625 x 100

% Decrease = 6.25 %

So, the percent decrease in high temperature from yesterday to today is 6.25%

estaba previsto destinar 3/14 de partes de una finca a plazas de aparcamiento pero finalmente han destinado 3/4 de lo previsto a zonas ajardinadas que fraccion de la finca se ha destinado a plazas de aparcamiento

Answers

Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.

La solución es:

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.

Es decir, se destino 3/4 de los 3/14 del total de la finca a zonas ajardinadas, entonces el 1/4 restante se dedico a plazas de aparcamiento, esto da:

(1/4)*3/14  = 3/56

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

In the figure below, if m<1 = (x + 16)° and m The < sign is angle

Answers

Answer:

Step-by-step explanation:

∠1 + ∠BFE = 180   {linear pair}

x + 16 + 3x + 20 = 180

x + 3x + 16 + 20 = 180   {Combine like terms}

4x + 36 = 180

Subtract 36 from both sides

4x = 180 - 36

4x = 144

Divide both sides by 4

x = 144/4

x = 36

what is one way to find the number of minutes in 7 hours?

Answers

Answer:

Seven dived by 60

Step-by-step explanation:

60 minutes makes an hour, so if you divide 7 hours by 60 minutes you could easily get an answer.

Multiplication.

because 1 hour = 60 minutes

and for you, there is 7 hours, you'd just do 7 x 60.

The answer would be the number of minutes (in those seven hours).

7 x 60 is 420 minutes just in case you were wondering.

Step-by-step explanation:

As per the question we have:

The y - intercept is b = -1The slope has same angle with x- and y - axis.

This can be a function with the slope of m = 1 or m = - 1 as these lines must be perpendicular to each other and make 90°/2 = 45° or 45° + 90° = 135° angle with the x- or y- axis.

So the lines could be:

y = x - 1 ory = -x - 1

Lines must be perpendicular to each other as they are cutting at y intercept -1

Slope intercept form of line

for slope -1

y=-x-1

For slope 1

y=x-1
