The formula for finding c...” No, you would divide it. The formula for finding circumference is 2 x pi x r, where r is the radius. 2 x r = d, where d is diameter.

Make x the subject of the formula where x is positive b= x -6 / x + 2

Anna007 [38]

Answer:

$b = \frac{x - 6}{x + 2} \\ b(x + 2) = x - 6 \\ bx + 2b = x - 6 \\ bx - x = - 6 - 2b \\ x(b - 1) = - 2(3 + b) \\ x = \frac{ - 2(3 + b)}{b - 1}$

Which of the following is the main of the set of data below? 30, 29, 28, 30, 24, 12, 26, 33, 25, 23

Marianna [84]

Answer:

The mean of the data is 26.

Step-by-step explanation:

Consider the provided data:

30, 29, 28, 30, 24, 12, 26, 33, 25, 23

Mean can be calculated as:

The average of all the data in a set.

$x=\frac{\Sigma x_{i}}{n}$

Therefore,

$x=\frac{30+29+28+30+24+12+26+33+25+23}{10}$

$x=\frac{260}{10}$

$x=26$

Thus, the mean of the data is 26.

Graph x+y=8 and x-y=4

yanalaym [24]

Answer:

See attached photo for graphs.

Step-by-step explanation:

The first step is to solve each equation for y, then graph using slop-intecept form...

x + y = 8

y = -x + 8 (subtract x from both sides)

x - y = 4

-y = -x + 4 (subtract x from both sides)

y = x - 4 (divide both sides by -1)
