If a pen is sold at rupees 8 with a loss of 20% find it cost priceplz tell me​

10 is the answer

Step-by-step explanation:

x-20%of x=8

x-20/100=8

100/100x-20/100x=8

80/100x=8

x=100*8/80

x=10

Step-by-step explanation:

SP of a pen =rs 8

loss%=20%

let cp be x

SP=CP-loss%*CP

8=x-20/100*x

8*100=100x-20x

800/80=x

10=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
