What does x equal if the equation is x/3 -3 = x/9 +3

3x - 27 = 27 + x

3x = x + 27 + 27

3x = x + 54

3x - x = 54

2x = 54

54/2 = x

x = 27

The answer is x = 27

Step-by-step explanation:

x/3-3 = x/9+3

3x-27 = x+27

3x-x = 27+27

2x = 54

x = 54/2

x = 27

c. 4 1/4 pounds

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
