I’m assuming you man degrees? Are these angles of a triangle?
This doesn’t really make sense because the angles in a triangle add up to 180° so your equation would be x+50+x+80+72=180
Combine like terms to get
2x+202=180
Then subtract 202 from both sides
2x=-22
So x would be -11 which doesn’t seem right lol
Remark
All vertical lines are of the form x = a. The y value only places where the point is on the grid.
For this particular question the x value of the point is where the vertical line is. At x = -2 draw a vertical line. The graph shows what this looks like.
The graph (x = - 2) is in red.
The point (-2,10) is green.
Answer:75

21 divded by 28 times 100= 75
Answer:
a. C = $ 10.50x b. 2 persons
Step-by-step explanation:
a. Write an equation to find how many people visited in a hour
Let x be the number of persons admitted in one hour. Since the movie theater charges 10.50 per person for admission, then the total admission fees would be C = charge per person × number of persons = $ 10.50 × x = $ 10.50x.
C = $ 10.50x
b. Solve an equation to find how many people visited in a hour
Given that C = $19.11, and C = $ 10.50x, so,
x = C/($10.50)
substituting C into the equation, we have
x = $19.11/$10.50
x = 1.82
Since we cannot have a decimal number of persons, x is rounded up to the nearest whole number. So,
x = 1.82
x ≅ 2
So, two people visited the theater in one hour.
