Answer:

Equilateral triangle is the correct answer.

Step-by-step explanation:

  • In the Equilateral triangle are all three sides have the same length /congruent
  • All the three interior angles are also similar in an equilateral triangle
  • Only the set of equilateral triangles contains members that are always similar to one another because all the angles are fixed and equal that is 60 degrees.
  • Rest(trapezoids, isosceles triangles,rectangles, pentagons) does not have fixed angles in it.

Answer:

The correct answer is b) 1100 adults and 1400 students.

Step-by-step explanation:

To find this, set up a system of equations in which x is the number of students who attend and y is the number of adults who attend.

First start by creating an equation for money made.

5x + 10y = 18,000

Now write an equation for the amount that attend.

x + y = 2,500

Now multiply the bottom equation by -5 and add the equations together.

-5x - 5y = -12,500

5x + 10y = 18,000

5y = 5,500

y = 1,100

Since this is the number of adults, we can plug into an original equation to find the number of students.

x + y = 2,500

x + 1,100 = 2,500

x = 1,400

What is the equation of line r <br> Write In slope intercept form
Ne4ueva [31]
If line r is parallel to line q, they have the same slope which is -2. You can use the point-slope formula <span>y-y₁=m(x-x₁) and plug in 8 for y and -8 for x. Solve for y to get the equation in slope-intercept form (y = mx + b). "M" is the slope.</span>
