256 is the answer to this question.
800x.32 equals 256 seventh graders
------------------------------------------------------------------------------------
Ratio
------------------------------------------------------------------------------------
Width : Length
2 : 5
Let x be the scale factor
Width : Length
2x : 5x
------------------------------------------------------------------------------------
Form equation and solve x
------------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
70 = 2(5x + 2x)
70 = 2(7x)
70 = 14x
14x = 70
x = 5
------------------------------------------------------------------------------------
Find Length and Width
------------------------------------------------------------------------------------
Length = 5x
Length = 5(5)
Length = 25
Width = 2x
Width = 2(5)
Width = 10
------------------------------------------------------------------------------------
Answer: Length = 25 cm, Width = 10 cm

Answer:
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
The two equal angles are called the base angles and the third angle is called the vertex angle
In this problem the triangle ABC is an isosceles triangle
so
The sum of the internal angles of a triangle is equal to 
so
Find the value of y
