Answer:

  • x+y≥20
  • 14x+12y≤420

Step-by-step explanation:

Variables are defined in the problem statement.

  x + y ≥ 20 . . . . . . . . at least 20 tickets were sold

  14x +12y ≤ 420 . . . . sales were at most $420

BD=BC, BD= 5x +26, BC= 2x+1, and AC = 43, find AB
Lostsunrise [7]
Imagine that points A, B, C and D are collinear and appears in that order from the left to the right. You want to find the measure of the first line segment AB. First, let's find the value of x.

BD = BC
5x + 26 = 2x + 1
5x - 2x = 1 - 26
3x = -25
x = -8.33

2(-8.33) + 1 = -15.67
So, BD=BC= -15.67

To find AB, the solution is as follows:
AC = AB + BC
43 = AB + (-15.67)
AB = 58.67
