Answer:
The given system of equations has infinitely many solutions.
Step-by-step explanation:
Given equations are:
4x-2y = 28
2x-y = 14
From equation 2:
Putting in equation 1:
When this happens in the solution of a system i.e. same constant on both sides of equation, the system of equations has infinitely many solutions.
Hence,
The given system of equations has infinitely many solutions.
Answer:
The answer is
Step-by-step explanation:
The triangle isosceles has two equal angles and two equal sides
The triangle ABC is an isosceles triangle -----> see the attached figure
-----> radius of the circle
------> angles of the base of the isosceles triangle ABC
------> by central angle ( vertex angle of the isosceles triangle ABC)
Remember that
the sum of the internal angles of a triangle is equal to
so
Answer: 8.3 feet
We know the area of 1 tile is:
(1)
We also know Jack used 103.75 tiles to cover the whole bathroom floor, which is a rectangle.
Remembering (1), we have that:
(2)
Which is also the area of the rectangle from which we only have the value of one of its sides, the width :
(3)
In addition, the area of a rectangle is given by the following equation:
(4)
Where is the length.
Substituting the value of the width written in (3) and the area (2) in equation (4):
(5)
We finally have the value of the length of the bathroom floor:
