8/100=2/25

Answer:

1) They forgot to multiply 2 times (2x+5)

2) x-2 is not equal to -(x+2).

3) The correct expression is [tex]x-1-1+2x=1-3x[/tex]

4) The correct way is [tex]4(2x+3)=3(1-3x)[/tex]

Step-by-step explanation:

1) In this case they forgot to multiply 2 times (2x+5). Let's recall we need to multiply (2x+5) to all terms of the equation.

2) Here, x-2 is not equal to -(x+2). If we see -(x+2) = -x-2 using the distributive property.

3) After multiplying by (3x-2) we will have:

[tex]x-1-(1-2x)=1-3x[/tex]

Apply the distributive property again, we will have:

[tex]x-1-1+2x=1-3x[/tex]

So the correct term is 2x not -2x.

4) When we multiply by (1-3x)(2x+3) on each side of the equation, we will have something like this:

[tex]\frac{4(1-3x)(2x+3)}{(1-3x)}=\frac{3(1-3x)(2x+3)}{(2x+3)}[/tex]

If we see we can simplify the same terms on each side of the equation.

[tex]4(2x+3)=3(1-3x)[/tex]

This is the correct way to do this.

I hope it helps you!

Answer:

d = 9.84 m

Step-by-step explanation:

The dimensions of an envelope are 9 inches by 4 inches.

We need to find the maximum possible length of the pencil.

Let it be d. It can be calculated using Pythagoras theorem such that,

[tex]d=\sqrt{9^2+4^2} \\\\d=9.84\ m[/tex]

So, the maximum possible length of the pencil is 9.84 m./

Answer:

$39

Step-by-step explanation:

First we need to find 35% of 60:

Step-by-step explanation:

Hello there!

First lets find the value of each irrational number

[tex]6 = 6\\\\\sqrt{29} =5.385164807\\\\2\pi =6.283185307\\\\3\sqrt{8} =8.485281374[/tex]

now we can easily put them in order from least to greatest

5.3,  6,   6.2,  8.4

then we change it to its irrational form

so the correct order would be

So Sophia ate 5% of the pizza

Answer:

Sophia ate 5%.

Step-by-step explanation:

Caden ate 20%. Zoe ate 50% more than him, so 150% of 20%. That is 20+half of 20, which is 30. So zoe ate 30%. Noah ate 50% more than her, so 150% of 30%, which is 45%. Add them together and get 95%. That leaves 5% for Sophia to eat.

Answer:

Graph B

Step-by-step explanation:

I typed the equation into Desmo and added a negative and that was the result.

Answer:

ba

Step-by-step explanation:

The solution of the given equation is x = 2.1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given that, an equation, 3ˣ = 10, we need to find the solution of it,

So, solving for x,

3ˣ = 10

Taking log both sides,

㏒ 3ˣ = ㏒ 10

Since, ㏒ aⁿ = n ㏒ a

Therefore,

x ㏒ 3 = ㏒ 10

x = ㏒ 10 / ㏒ 3

x = 1/0.477

x = 2.095

x ≈ 2.1

Hence, the solution of the given equation is x = 2.1

The point that is equidistant to all sides of a triangle is called the incenter.

The incenter is located at the intersection of bisectors of the interior angles of a triangle.

b)

The point that is equidistant to all vertices of a triangle is called the circumcenter.  

The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.

c)

See the attachment

The blue lines and their intersection shows the incenter.

The red lines and their intersection shows the circumcenter.

As we see the red point- the circumcenter is closer to vertex B.

Answer:

9x/y³

Step-by-step explanation:

The simplification of the expression 9x⁰y⁻³ will be 9/y³.

Index (indices) in Maths is the power or exponent which is raised to a number or a variable.

In another word the mathematics of power or exponent of any number is called indices.

As per the given expression,

9x⁰y⁻³

By the law of indices that, [tex]x^{-m}[/tex] = 1/[tex]x^{m}[/tex]

9x⁰y⁻³ = 9x⁰ × 1/y³

⇒ 9(1)/y³ = 9/y³
