Step-by-step explanation:

angle ACB=75° (being inscribed angle)

Angle BCD=105° (sum of straight line)

angle BCD + angle BQD=180° (opposite angle of quadrilateral inscribed in circle is supplemetry)

105° + x =180°

x= 75°

7x + 6(-3 + 4x) = 199<br>what does x equal?
tresset_1 [31]

Simplify. Note the equal sign. What you do to one side, you do to the other. Follow PEMDAS.

Isolate the x.

First, distribute 6 to all terms within the parenthesis

6(-3) = -18

6(4x) = 24x

7x - 18 + 24x = 199

Simplify. Combine like terms

31x - 18 = 199

Isolate the x. Add 18 to both sides

31x - 18 (+18) = 199 (+18)

31x = 199 + 18

31x = 217

Isolate the x. Divide 31 from both sides

31x/31 = 217/31

x = 217/31

x = 7

7 is your answer for x

hope this helps

You are planning to take a group of friends to the movies for your birthday. The local movie theater charges $12.99 per person.
enot [183]
The answer is 6 People. You make the two equations first 12.99x and 8.99x+20. And then make them equal each other 12.99x = 8.99x+20. Then you use algebra to solve for the x and you get an answer of 5. That is the number of people that would cause the two prices to break even (be the same price). So in order for the group rate to be the better deal you need 6 people to attend.
