Why does the multiplication property of equality not allow us to divide both sides of an equation by zero?​

Mathematics
1 answer:
Anna71 [15]3 years ago
6 0

First of all, recall that division by zero is undefined; it's nonsensical; it's just not allowed.So zero certainly needs to be excluded when dividing.

But what about multiplying by zero?

The problem is that multiplying by zero can change the truth of an equation:

It can take a false equation to a true equation.

To see this, consider the false equation ‘

2 = 3

Multiplying both sides by zero results in the new equation

2 ⋅ 0 = 3 ⋅0 (that is, ‘0 = 0’), which is true.

Kelly makes $10 more per hour than her regular pay when she is working overtime. Yesterday, she worked 8 regular hours and 4 ove
Mademuasel [1]

Kelly's regular pay is $10 per hour and overtime pay is $20 per hour.

<h3>What is equation?</h3>

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. Solving this equation, we get the value of the variable x as x = 7.

Here,

Let her regular pay be x and overtime pay be y.

8x+4y=160

y=x+10

8x+4(x+10)=160

8x+4x+40=160

12x=120

x=10

y=x+10

=10+10

=20

Kelly receives a regular pay rate of $10 and a $20 overtime pay.

How many edges does a polyhedron with 28 faces and 40 vertices have calculator?
emmasim [6.3K]
Hey user!

your answer is here..

we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.

Euler's formula = F + V - E = 2

given :-

faces = 28, verticies = 50 and edge = ?

we know that F + V - E = 2

therefore 28 + 40 - E = 2

==> 68 - E = 2

==> - E = 2 - 68

==> - E = - 66

==> E = 66

hence, the number of edges of the polyhedron is 66.

cheers!!
