Answer:

x = 2.25

Step-by-step explanation:

8:6

So, 8/6 = 4/3 or 1.33333333 (decimal multiplier)

Therefore, 8 divided by 4/3 = 6.

Then, we could also do 3 divided by 4/3= 9/4 or 2.25.

2.25 x 4/3 = 3.

Answer:

x = 2.25

setting up proportionality:

[tex]\rightarrow \sf \dfrac{8}{3} = \dfrac{6}{x}[/tex]

[tex]\rightarrow \sf 8x = 18[/tex]

[tex]\rightarrow \sf x = \dfrac{18}{8}[/tex]

[tex]\rightarrow \sf x = 2.25[/tex]

Answer:

x = 4

y = 3

Step-by-step explanation:

x - 4.6y = -9.8

-x + 4.8y = 10.4

multiply both equations by 5 to remove the decimals in the variables.

we then get this:

5x - 23y = -49

-5x + 24y = 52

multiply one of the equations by -1 to get this

-5x + 23y = 49

-5x + 24y = 52

now subtract the equations

0x -y = -3

y = 3

plug back into equation to get value of x

x - 4.6(3) = -9.8

x - 13.8 = -9.8

x = 4

Answer:

y = 3x + 1

Step-by-step explanation:

You have to use y = m x + c to find the equation of the line.

Here,

m ⇒ slope

c  ⇒  y - intercept

First let us find the slope by using the below formula.

For that, let us use the given coordinates.

( -1 , -2 ) ⇒ ( x₁ , y₁ )

(-2 , -5)  ⇒  ( x₂ , y₂ )

m = [tex]\frac{y_1-y_2}{x_1-x_2}[/tex]

m = [tex]\frac{-2-(-5)}{-1-(-2)}[/tex]

m = [tex]\frac{-2+5}{-1+2}[/tex]

m = [tex]\frac{3}{1}[/tex]

m = 3

Now we have to find the y - intercept.

For that we can use any coordinate for that.

Let us use ( -1 , -2 ) coordinate.

y = m x + c

-2 = 3 × -1 + c

-2 = -3 + c

- 2 + 3 = c

1 = c

Let us write the equation of the line now.

y = m x + c

y = 3 x + 1

Answer:

y=X+2

Step-by-step explanation:

you can use the equation y=Mx+c to give this solution!

Answer:

Step-by-step explanation:

Find the slope using the points

[tex]Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\dfrac{6-2}{4-0}\\\\\\=\dfrac{4}{4}\\\\\\=1[/tex]

m= 1.

y = mx + c

y = 1*x+ c

y = x + c

In this equation substitute x = 0 and y = 2 and find the valu of c

2 = 0 + c

c = 2

Answer:

49.55

Step-by-step explanation:

okay so, what we do is
Get 15% of 23
Get 15% of 32

15% of 23 is 3.45

15% of 32 is 4.80

Now we do

23 - 3.45

32 - 4.80

23 - 3.45 is 19.55

32 - 4.80 is 27.2

This is the part im not 100% on

27.20 + 19.55 is 46.75

6% of 46.75 is 2.80

46.75 + 2.80 is 49.55

Now i dont know if its that way or if you apply the 6% sale tax to each individual item

Question: A clothing store is having an anniversary sale. Every piece of clothing in the

store is 15% off. If Lara bought a belt that was originally priced $23 and a

sweater that was originally $32, what is the final price after 6% sales tax?

Answer: $44.89

Step-by-step explanation:

23+32=55

15% of 55 = $8.25

leaves $47.75

6% of 47.75 = $2.87

leaves $44.89

It would take about 23.1 months for the plant population to be 138 plants.

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Given:

[tex]P(m)=19.3(1.089)^m[/tex]

Where P is the plant population after m months.

For a population of 138 plants:

[tex]138=19.3(1.089)^m\\\\m*ln(1..089)=ln(7.15)\\\\m=23.1[/tex]

It would take about 23.1 months for the plant population to be 138 plants.

The net to compute the surface area of the three-dimensional figure is 166 square units.

The surface area is the area calculated for the three-dimensional object. As the three-dimensional object is made up of 2D faces, the surface area is the sum of the areas of all the faces of the figure.

A cuboid is a three-dimensional figure having length, width, and height. The surface area of a cuboid can be calculated by adding together the areas of the six faces.

For the given cuboid, length l = 8 , width w = 5 and height h = 5.

The surface area of the figure is given by;

[tex]\rm Area\ of \ Cuboid = 2 lw + 2 lh + 2 wh\\\\Area\ of \ cuboid= 2(7)(5)+2(7)(4)+2(5)(4)\\\\ Area\ of \ cuboid= 70+56+40\\\\Area\ of \ cuboid= 166 \ units^2[/tex]

Hence, the net to compute the surface area of the three-dimensional figure is 166 square units.
