Answer:
C
Explanation:
You could solve this in the elimination way that I have been done in here.
I use Jason as an example that he paid $11.84 for 5t ( tacos ) + 1q ( quesadilla )
Therefore we could do the elimination if the taco cost 3.45 x 5 = 17.25, would be over the cost.
-> Cross B answer
Then we take 1.57 x 5 = 7.85. 11.84 - 7.85 = 3.99, which it is not 3.39 => Cross D answer.
Therefore the cost of tacos need to be 1.69 because there have been a repetition in both A& C
1.69 x 5 = 8.45. $11.84 - 8.45 = $3.39 for quesadillas.
Which it proves for the answer is C

Answer
x=33
Step-by-step explanation:
since they're both on the same line we must equal them to 180.
18 + x + 4x -3 = 180 (Now you simplify terms)
5x + 15 = 180 (Subtract the 15 from both sides)
5x = 165 (divide by 5 to isolate the variable)
x = 33 (Hope I was able to help :) )
Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13
