60 + $50.45 x equals $57 .95 cents x

x = 8

Step-by-step explanation:

The first step would be to move all terms with x to one side of the equation:

60 + 50.45x = 57.95x --> 60 + 50.45x - 50.45x = 57.95x - 50.45x -->

60 = 7.50x

The last step to obtain x is to divide both sides by the coefficient of (number next to) x:

60/7.50 = 7.50x/7.50 --> 8 = x

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
