An electric can opener is worth 38 dollars when it is new. After each year it is worth half what it was the previous year. What will it’s worth be after 4 years?

2.37

Step-by-step explanation: we would take value and half it 4 times. Taking the vaule a dividing it by 2 and taking that vaule and diving it again by 2 up to 4 times

definitely a. the others have almost all data points on one side of the line.

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
