Best buy sells iPhones amd Samsung. Thy have 81 phones in the store. If the number of iphones is twice the number of Samsung's how many of each phone does the story carry?

[tex]P_1=2\cdot2x+2\cdot(2x+7)=8x+14[/tex]

and

[tex]P_2=2x+x+x+8+x+6+x+2x=8x+14[/tex]

Seems like thier perimeters are equal.

I dont know the exact way that the equations are written but ill give it in

Answer:

18 bags

Step-by-step explanation:

If you put 3 chocolates in 18 bags you get 54 chocolates in total. Because 3 cannot be split down any lower it will provide the maximum number of bags able to be created.

There will be 3 chocolates and 4 candies in each bag. Making it evenly split to its greatest possibility.

Step-by-step explanation:

There are 2 1/3 inches in  1 2/5 groups of 1 2/3 inches.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

There are 1 2/5 groups of 1 2/3 inches.

Now,

Since, There are 1 2/5 groups of 1 2/3 inches.

Hence, The number of inches = 1 2/5 × 1 2/3

                                              = 7/5 × 5/3

                                              = 7/3 inches.

Thus, There are 2 1/3 inches in  1 2/5 groups of 1 2/3 inches.

Answer:

15/4

Step-by-step explanation:

Equation: 40(5+x)=70*5+0x

Solve:

200+40x=350

40x=150

x = 15/4

15/4 gallons is the answer.

3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the amount of water in galloons needed to be added to make 40% sugar. Hence:

40% of (x + 5) = 70% of 5

0.4x + 2 = 0.7 * 5

0.4x = 1.5

x = 3.75

Therefore 3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

Answer:

The dimensions of this rectangle are 65 in by 39 in ⇒ B

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ The perimeter of the rectangle = 2(length + width)

∵ The perimeter of a rectangle is 208 inches

∴ 208 = 2(length + width)

→ Divide both sides by 2

∴ 104 = length + width

∵ The ratio  of its length to its width is 5: 3

∴ The sum of the ratios = 5 + 3 = 8

→ By using the ratio method

→  length  :  width  :  length + width

→  5           :  3         :  8

→  x            :  y         :  104

→ By using cross multiplication

∵ x × 8 = 5 × 104

∴ 8x = 520

→ Divide both sides by 8

∴ x = 65

∵ y × 8 = 3 × 104

∴ 8y = 312

→ Divide both sides by 8

∴ y = 39

∵ x and y represents the length and the width of the rectangle

∴ The length = 65 inches

∴ The width = 39 inches

∴ The dimensions of this rectangle are 65 in by 39 in

Answer:

we need a figure

Step-by-step explanation:

Step-by-step explanation:

(1) Create a table containing a few values of x and y

y - 3 = ½(x + 2)

   y = ½(x + 2) + 3

x     y

-10    -1

-6      1

0      3

6      7

10     9

(2) Plot your points

Draw dots at the coordinates of each point.

(3) Draw the graph

Draw a smooth line through the points.

Extend the line in both directions to the edges of the plot area.

Your graph of y - 3 = ½(x+2) should look like the figure below.

Answer:

y = -2x - 4.

Step-by-step explanation:

The points marked are (-2,0) and (0,-4).

The slope of line =  (-4-0) / (0- -2)

= -4/2 = -2.

The y-intercept is at y = -4,

so the equation required is y = -2x - 4.

Answer:

y = - 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line

m = [tex]\frac{-4-0}{0+2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

The line crosses the y- axis at (0, - 4) ⇒ c = - 4

y = - 2x - 4 ← equation of line

The approximate number of DVDs in Paulette’s collection after 14 months is 75 DVDs.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

let the collection of DVDs ne n and the time spend is m.

and, the Equation for the situation is

n = 1.8 m + 25

Now, the number of DVDs in collection after 14 months is

= 1.8 (14)+ 25

= 50.2

So, the total number of DVDs are

= 50 + 25

= 75
