HEY! PLEASE HELP ME WITH THIS MATH QUESTION! THE CORRECT ANSWER SHALL BE MARKED AS BRAINLIEST AND I WILL FOLLOW YOU (you will also get points) THANKS!!xoxo

a battery costs £0.43

Step-by-step explanation:

Set up an equation

11b+b+4.84=10

Subtract 4.84 from both sides

12b+4.84=10

     -4.84=-4.84

12b=5.16

Divide 12 on both sides

b=5.16/12

b=0.43

(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
