Find values of x and y??

Answer:

x = 80
y = 122

Step-by-step explanation:

The angles marked with x-expressions are complementary, so ...

(3/4x -2) + (2/5x) = 90

x(3/4+2/5) = 92 . . . . . . . add 2

x(23/20) = 92 . . . . . . . . combine the fractions

x = 92(20/23) . . . . . . . . multiply by 20/23

x = 80

The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...

y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32

y = 122

Solve the following system of equations. State whether the system is consistent and independent, consistent and dependent, or in

Makovka662 [10]

Answer:

Inconsistent

Step-by-step explanation:

If a system has at least one solution, it is said to be consistent.

If a consistent system has exactly one solution, it is independent.

If a consistent system has an infinite number of solutions, it is dependent.

A system of equations is called an inconsistent system of equations if there is no solution.

Given the system of two equations

$\left\{\begin{array}{l}-4x+7y=28\\ \\4x-7y=32\end{array}\right.$

Add these two equations:

$(-4x+7y)+(4x-7y)=28+32\\ \\-4x+7y+4x-7y=60\\ \\(-4x+4x)+(7y-7y)=60\\ \\0=60$

This is false statement, hence, the system of two equations has no solution and is inconsistent.
