Answer:
"A trapezoid is a quadrilateral with two parallel sides and, usually, two nonparallel sides."
Step-by-step explanation:
"A trapezoid is a quadrilateral with two parallel sides and, usually, two nonparallel sides. A quadrilateral is a geometric shape that has four sides. Some specialized types of trapezoid are the parallelogram and the isosceles trapezoid.
The two parallel sides of a trapezoid are its bases while the legs are the nonparallel sides. Geometric analysis of a trapezoid includes calculating the height, median and area. The height of a trapezoid is a line segment that runs perpendicular to the bases. The median, or mid-segment, is a line that is parallel to the bases and connects the midpoints of each leg. The area is calculated with a formula using the lengths of each base and the height.
A parallelogram is usually defined as a trapezoid, although it has two pairs of parallel sides instead of just one. An isosceles trapezoid has congruent base angles and equal leg lengths."

Step-by-step explanation:
(a) 3(x-1) = 2x-3+3x
3x-3 = 5x-3
3x-5x = 0
-2x =0
x = 0
(b) 4x +1/3 = x - 5/2
4x-x = -5/2-1/3
3x = -17/6
x = -17/6 . 1/3
x = - 17/18
(c) 1/2 x - 17 = -23
1/2 x = -6
x = -6.2
x = - 12
Answer:
A=85.50n
Step-by-step explanation:
So to find the cost for any amount of adults, you need to multiply $85.50 by the adults (n). Then that will equal the base ticket price (A).
