Which value of x makes the equation 1.25(4x+2)=32.5

Answer:

3x^(2)+3x+4

Step-by-step explanation:

Answer:

[tex]3x^{2} +3x+4[/tex]

Step-by-step explanation:

1.)Remove the parentheses [tex]3x^{2}-4x+6+7x-2[/tex]

2.)Group like terms

3.)Add similar elements -4x-7x=3x = [tex]3x^{2}+3x+6-2[/tex]

4,)Add/Subtract the numbers 6-2=4

5.)[tex]=3x^{2} +3x+4[/tex]

Answer:

$10

Step-by-step explanation:

To calculate markup, you take you cost and then multiply it by the markup percentage (in decimal form), then add that number to the original cost.  So the formula will look like this.

Selling Price = Cost + (Cost X Markup Percentage)

Let's use X to be the selling price you are looking for.

X = $7 + ( $7 x 0.43)   0.43 is the decimal value of 43 percent

Work on the numbers in parentheses first:

$7 x 0.43 = $ 3.01

now add that to the original cost:

$7 + $ 3.01 = $ 10.01

Round to the nearest dollar and you have $10.

The manager made the mistake of multiplying the markup percentage and the original cost.

$7 x 0.43 = $ 3.01

He subtracted the markup instead of adding it to the original cost.

Step-by-step explanation:

% change = (new - original)/original × 100

= (8,000 - 5,000)/5,000 × 100

= 3,000/5000 × 100

= 60%

Answer:

Postulates and conjectures are similar in that they are both used in mathematical proofs. The difference between them is that whilst a conjecture is a opinion that is put forward without proof, and that simply represents a belief, a postulate it something that is assumed true (but still does not have any proof behind it).

Step-by-step explanation:

Answer: Postulate – this is also called as axiom. This study is accepted without asking for any proof. This is considered as true without further proof. IT is simply considered as self-evident. It is usually agreed by anyone to be true and acceptable.

Example of postulate is to prove a simple triangle as congruent.

While conjecture – considered as proposition in which it needs to provide value proof or evident in order for it to be considered as true.

Examples of conjecture are four color theorems and Fermat’s Last theorem.

Answer:

42.9% or 43%

Step-by-step explanation:

270÷630=0.4285714286

0.4285714286 × 100 = 42.85714286

Rounded - 42.9% or 43%

Answer:

y=28/3x+6

Step-by-step explanation:

If you use the slope formula,     y2-y1

                                                      _____\

                                                       x2-x1

You would get that the slope is 23/3 and you can see the y-intercept is 6 so you would get y=28/3x+6.                                                        

Answer:

4.25x ≤ 50

Number of drink = 11

Step-by-step explanation:

Given:

Amount of gift card = $50

Each drink cost = $4.25

Find:

Number of drink

Computation:

Assume;

Number of drink = x

So,

4.25x ≤ 50

x ≤ 11.76

so,

Number of drink = 11

Answer:

Equation should be: 15x + 5 = y

Step-by-step explanation:

I do not know the amount of money that he owed

For Example :

15(12) + 5 = y

180 + 5 = y

y = 185

Sorry if I'm incorrect

Answer:

maria : 1/3 =0.3 line on top of three

franco:1/4=0.25

Step-by-step explanation:

tried my best hope its right :)

Answer:

Maria: 1/3 cups for each gallon

Step-by-step explanation:

Maria: 2/3 for every 2 gallons.  2/3:2

Franco: 1 1/4 for every 5 gallons.  1 1/4/:5

Okay, so I'm actually going to do it my way.

Maria : [tex]\frac{2}{3} = 4/6\\\frac{4}{6} /2 =2/6[/tex]

So, I simply turn it into a bigger fraction and cut it in half!

So, Maria uses 1/3 of a cup for each gallon

Hope this will help you figure out Franco's!!!

Answer: two points

Step-by-step explanation:

The intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

The intersection of a circle and a regular hexagon.

As we know, the polygon is a geometric figure with a finite number of sides in two dimensions.

On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

If the circle and regular hexagon will intersect on a coordinate plane then it will create two intersection points.

Thus, the intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.
