Mr. Smith lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. What percentage did Mr. Smith decreased he weighed?

A. 4%
B. 7%
C. 10%
D. 15%

4%

Step-by-step explanation:

4%=00.4

240+10=250  starting weight

00.4 × 250= 10

why can't you?

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
