Circle O has tangent AB and secant AC as shown. Arc BC measures 4x + 20. Arc BE
measures 2x - 10. Which is the correct way to set up the equation if you are trying to find the value of x?

Multiple choice:

a) 50=0.5(2x-10 - (4x+20)
b) 50=0.5(2x - 10 + 4x + 20)
c) 50=0.5(4x + 20-(2x - 10))
d) 50=0.5(4x +20 - 2x - 10)

Please help!

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

here try this one

3a-24=0

60: 45 =12: 9 =4: 3 so the answer is 4: 3
