When two equal signs is placed between two algebraic expressions a what is formed
Vikki [24]

If we have two sides equal each other, then we called the statement "equation"

Example:

2x + 3 = 5x - 2 is called an equation

2x + 3 is an algebraic expression

5x - 2 is an algebraic expression

When we put = sign between them, they called an equation

Then when two equal signs are placed between two algebraic expressions, they formed an equation

The answer is an equation

Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. Which statement best describes Maya’s expre
harina [27]

<u>Answer:</u>

The statement, Maya’s expression will generate the correct sum because of the associative property will describe the best.

<u>Solution: </u>

Maya’s expression will generate the correct sum because of the associative property.

Maya wrote the expression 3+5+4.5

As per commutative property of addition if we change the order still the sum will be same, which means (a + b) = (b + a)

Here also, (3 + 5) + 4.5 = 8+4.5 = 12.5

Again 3 + (5+4.5) = 3+9.5 = 12.5

As both the results are same, hence this is meeting the commutative property of addition.

What is the following quotient?
Sergio039 [100]

Answer:

\frac{\sqrt{3} }{4}

Step-by-step explanation:

\frac{1}{1+\sqrt{3} }

basically we want to get rid of the √3 on the denominator

to do so we multiply it by itself so it is a perfect square

but whatever we do to the top we must do to the bottom so we multiply the numerator and denominator by √3

\frac{1*\sqrt{3} }{1+\sqrt{3}*\sqrt{3}  }=\frac{\sqrt{3} }{1+\sqrt{9} } =\frac{\sqrt{3} }{1+3} =\frac{\sqrt{3} }{4}

notes : √3 × √3 = √9 which is a perfect square that simplfies to 3
