Answer:
a) Figure B and Figure C
b) Figure C
c) Figure A, Figure B, and Figure C
Step-by-step explanation:
a) Rectangles are shapes that have four sides, and four right angels. Right angles are angles that are 90 degrees.
The only shapes with four sides AND four right angles are Figure C and Figure B.
b) Squares are shapes with four EQUAL sides and four right angles. The only shape with four equal sides and four right angles is Figure C.
c) Parallelograms are any shapes with four sides. All of these shapes have four sides.

Answer:
- 65 couple tickets
- 50 individual tickets
Step-by-step explanation:
The two equations are for the revenue and the number of attendees.
3p +5c = 475 . . . . . . revenue from ticket sales (dollars)
p +2c = 180 . . . . . . . number of attendees (2 persons per couple)
Substituting (180-2c) for p in the first equation, we get ...
3(180 -2c) +5c = 475
540 -c = 475 . . . . . . . . . simplify
540 -475 = c = 65 . . . . . add c-475
p = 180 -2(65) = 50 . . . . find p from c
65 couple tickets and 50 individual tickets were sold.
Answer:
Option C: 11 is the correct answer.
Step-by-step explanation:
Given that:
Length of base of isosceles triangle = b = x
The length of leg of triangle = a = 3x-7
Perimeter of triangle = 63
Perimeter of an isosceles triangle is given by
Perimeter = 2a + b
Putting values in the formula
63 = 2(3x-7) + x
63 = 6x-14+x
63 = 7x-14
63+14=7x-14+14
77=7x
7x=77
Dividing both sides by 7
The value of x is 11.
Hence,
Option C: 11 is the correct answer.
