Answer:

x = -2

Step-by-step explanation:

2(3x - 5) + 4 = -18

Distribute the 2

6x - 10 + 4 = -18

6x - 6 = -18

Add 6 to both sides

6x = -12

Divide both sides by 6

x = -2

Check:

2(3x - 5) + 4 = -18

substitute x = -2 into the original equation

2(3(-2) - 5) + 4 = -18

2(-6 - 5) + 4 = -18

2(-11) + 4 = -18

-22 + 4 = -18

-18 = -18

So x = -2 is true.

Answer:

x=-2

Step-by-step explanation:

2(3x-5)+4=-18

We move all terms to the left:

2(3x-5)+4-(-18)=0

We add all the numbers together, and all the variables

2(3x-5)+22=0

We multiply parentheses

6x-10+22=0

We add all the numbers together, and all the variables

6x+12=0

We move all terms containing x to the left, all other terms to the right

6x=-12

x=-12/6

x=-2

Answer:

markup 75%

Step-by-step explanation:

The difference in prices is $70-$40=$30.

So, we need to find what percentage of 40 is 30. We do this by dividing: 30/40=0.75, which is 75%. So, the markup is 75%.

Answer:

28.27 ft²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius

Plug in 3 for the radius

[tex]A=\pi (3)^2\\A=9\pi[/tex]

[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)

Therefore, the area of the circle is 28.27 ft².

I hope this helps!

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

Step-by-step explanation:

An area cannot be in feet. It must be in a square unit such as square feet.

A = r²

A = ()(3 ft)²

A = 9 ft²

A = 9(3.14159) ft^2 = 28.3 ft²

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

Answer:

y = - x + 3

or

x + y = 3

Step-by-step explanation:

Line is passing through the points (3, 0) & (0, 3)

y-intercept (b) = 3

Slope of the line (m) = (3 - 0)/(0 - 3) = 3/(-3) = - 1

Now, required equation of line is given as:

y = mx + b

y = - 1*x + 3

y = - x + 3

or

x + y = 3

Answer:

This means that the rate of change of your position is negative and you have a negative velocity. A negative velocity does not mean that you are slowing down

Step-by-step explanation:

The meaning to have a negative change is, it is decreasing over time.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

We have to explain the meaning to have a negative change.

Hence, We get;

A positive rate of change means that the quantity you are measuring is increasing over time, and a negative rate of change means that it is decreasing over time.

Thus, The meaning to have a negative change is, it is decreasing over time.

If there are two children in the Patel family. They are twins of the same age. Then zero is  the range of their ages

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

There are two children in the Patel family.

They are twins of the same age.

Let x be the age of two children.

As they are twins so the age of children's is same.

The formula of range is highest minus lowest.

range = highest - lowest

Range=x - x

Range =0

Hence, the range of their ages is 0.

Step-by-step explanation:

Given - For each pair of pants, Pedro has 2 shirts.

To find - Which models show this relationship?

Proof -

Let Pedro has total number of pair of pants = x

Now,

As given

For 1 pair of pants , Pedro has total number of shirts = 2

⇒For x pair of pants , total number of shirts = 2x

So, Total number of clothes Pedro has = x + 2x = 3x

Answer:   512m³

Step-by-step explanation:

v = whl

The volume for left building:

v = w x h x l

v = 4 x 10 x 8

v = 320 m³

The volume for right and lower building:

v = w x h x l

v = 8 x 4 x 6

v = 192 m³

The total volume for the entire Charter School is: 320m³ + 192m³ = 512m³

First you would make the equation

(1/2x - 1/4)(5x^2 + 6)

afterwards you would multiply like normal binomials\

5/2x^3 + 3x - 5/4x^2 - 6/4

Then simplify

5/2x^3 - 5/4x^2 + 3x - 3/2

Remember to put them in order from the most roots to the least.
