What is the answer to 5x=7x-2 (x-8)

no solutions

Step-by-step explanation:

5x=7x-2 (x-8)

The first step is to distribute the -2

5x = 7x -2*x -2*-8

5x = 7x -2x+16

Combine like terms

5x = 5x+16

Subtract 5x from each side

5x-5x = 5x-5x+16

0 =16

This is never true, so there are no solutions

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

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.
