Everything in a store that is going out of business is on sale for a 60% off discount.
Janine wants a power drill that is priced at
$67.95 and a set of drill bits that is priced at
$18.49. The sales tax is 7%. How much will
Janine pay after the discount and the sales tax?

answer: 1 + 1 = 11

step-by-step explanation:

(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
