Answer:
Multiply both sides by 2
Subtract l from both sides
Divide each side by 3
(2R -l)/3 =w
Step-by-step explanation:
R = (l+3w)/2
Multiply both sides by 2
2R = 2* (l+3w)
2R = l+3w
Subtract l from both sides
2R - l = l-l +3w
2R -l = 3w
Divide each side by 3
(2R-l) /3 = 3w/3
(2R -l)/3 =w
The equation of a circle:

(h,k) - the coordinates of the centre
r - the radius
The midpoint of the diameter is the centre of a circle.
The coordinates of the midpoint:

(x₁,y₁), (x₂,y₂) - the coordinates of endpoints

The centre of the circle is (2,5).
The radius is the distance between an endpoint of the diameter and the centre.
The formula for distance:


The radius is 5.
K is the slope of the line formed by connecting the points.
Use slope formula:

where the 2 points are the end points of the line (First and last going Left to right)

Substitute into slope formula

You can check if this is correct by going back to graph and going "up 7" and "over 2" to get from one point to the next.
Answer:
There is a 1/6 chance of rolling a certain number and 1/2 chance of getting a heads.
1/6 x 1/2 = 1/12 so C.
1 is the chance of getting the wanted number / 6 is all the numbers in total
When there are multiple chances you just multiply the fractions
Step-by-step explanation:
Answer:
x=48
Step-by-step explanation:
What number out of 75 gives you 64%
What number out of 75 gives you 64 out of 100
x 64
------------ = -----------
75 100
Using cross product
100x = 64*75
100x =4800
Divide each side by 100
100x/100 = 4800/100
x=48
