The equivalent expression of \frac{\frac 2x - \frac 4y}{-\frac 5y + \frac 3x} is \frac {2(y - 2x)}{ 3y-5x}

<h3>How to determine the equivalent expression?</h3>

The complete question is in the attached image

We have:

\frac{\frac 2x - \frac 4y}{-\frac 5y + \frac 3x}

Take the LCM

\frac{\frac {2y - 4x}{xy}}{\frac{-5x + 3y}{xy}}

Divide through by xy

\frac {2y - 4x}{-5x + 3y}

Rewrite as:

\frac {2y - 4x}{ 3y-5x}

Factor out 2

\frac {2(y - 2x)}{ 3y-5x}

Hence, the equivalent expression of \frac{\frac 2x - \frac 4y}{-\frac 5y + \frac 3x} is \frac {2(y - 2x)}{ 3y-5x}

Could 10.3cm 4.4cm and 8.3 cm be the side lengths of a triangle yes or no
evablogger [386]

Answer:

No

Step-by-step explanation:

As you probably know, triangles have 3 sides. The longest side is called the hypotenuse. In this case, the hypotenuse is 10.3. Now, you might or might not know the pythagorean theorem, which states that the <em>a² + b² =c ². </em>

In this case, we can say that 4.4 is <em>a </em>and 8.3 is <em>b. </em>Now if we square 4.4 and add it to 8.3 squared, we get 88.25. However, if you square 10.3, you get 106.09. Thus, the values cannot be this way. So, your answer is no.

For which values of P and Q does the following equation have infinitely many solutions ?
solmaris [256]

Answer:

(P, Q) = (-75, 57)

Step-by-step explanation:

The equation will have infinitely many solutions when it is a tautology.

Subtract the right side from the equation:

Px +57 -(-75x +Q) = 0

x(P+75) +(57 -Q) = 0

This will be a tautology (0=0) when ...

P+75 = 0

P = -75

and

57-Q = 0

57 = Q

_____

These values in the original equation make it ...

-75x +57 = -75x +57 . . . . . a tautology, always true

Expression 1:
e-lub [12.9K]
1. Did it mentally think it’s 16. Make sure to yield to order of operations.
2. Because none of the operations are multiplication or division, parenthesis can be put anywhere that isn’t between exponents and it will yield 22.

What is a common tool between length and mass
Tema [17]
Seems like a wordplay question.

A "scale" is used for measuring length.

A different sort of "scale" is used for measuring mass.
