Answer:

She pays 0. 05$

Step-by-step explanation:

Cost per once is 40, peanut butter is 5. 20 divide those 2 you will get 0. 13

Now divide it by the butter price 2. 70/15

It will be 0. 18

Subtract 0. 18-0. 15

Mia can purchase a 40-ounce jar of peanut butter for $5.20 or a 15-ounce jar for $2.70.  How much does Mia save per ounce by buying the 40-ounce jar?

She pays 0.05$

As another example, let's say we want to divide x^2+5x+6 all over x^3+7 as one big fraction

We would type in Division[x^2+5x+6, x^3+7]

Answer:

The worth of the TV after 3 years is £809.90208

Step-by-step explanation:

The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine

The given parameters of the TV are;

The amount at which Collin buys the TV, P = £720

The rate at which the TV depreciates at, R = 4%

The number of years the depreciation is applied, T = 3 years

The amount the TV is worth after three years, 'A', is given as follows;

[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]

By plugging in the known values, we have;

[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]

The amount the TV is worth after three years, A = £809.90208

Your answer is. a=14-3b

The equation of 'b' in terms of 'a' will be b = (14 - a) / 3.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The equations are given below.

a = 3t - 10          ...1

b = 8 - t             ...2

From equation 2, then we have

b = 8 - t

t = 8 - b

Put the value of t in equation 1, then we have

a = 3(8 - b) - 10

a = 24 - 3b - 10

a = 14 - 3b

3b = 14 - a

b = (14 - a) / 3

The equation of 'b' in terms of 'a' will be b = (14 - a) / 3.

hhmmmmmhmmmm hmhmmmm hmmm yeah i got nothing

Step-by-step explanation:

Given:

The area model.

The area of the shape is 82 square units.

To find:

The correct equation for the given situation.

Solution:

We know that, area of a rectangle is

[tex]Area=Length \times Width[/tex]

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is

[tex]A_1=(x)\times (3x)=3x^2[/tex]

[tex]A_2=(x)\times (4)=4x[/tex]

[tex]A_3=(3)\times (3x)=9x[/tex]

Now, the total area is equation to 82 square units.

[tex]A_1+A_2+A_3=82[/tex]

[tex]3x^2+4x+9x=82[/tex]

[tex]3x^2+13x=82[/tex]

Since the required equation is [tex]3x^2+13x=82[/tex], therefore, the correct option is C.

Step-by-step explanation:

-3x + 7y = 5x + 2y (you subtract the 2y from both sides)

-3× + 5y = 5x (then add 3x to both sides)

5y = 8x (use x = - 5)

5y = 8x - 5 = -40 (both sides are divided by 5)

y = -8

answer is (-5, -8)

Answer: r>13

Step-by-step explanation:

The sign is less than so r +8 has to be 20 or less.

Answer:

- 5/4

Step-by-step explanation:

Answer:

x=4 and y=5 commonly notated as (4,5)

Step-by-step explanation:

The equations

Equation 1: 3x+3y=27

Equation 2: x-3y= -11

The second equation looks like it will be the easiest to rearrange.

x-3y = -11

add 3y to each side to get

x = 3y-11

Substitute that in for x in equation 1 so

3x+3y=27

turns into

3(3y-11) +3y =27

multiply out to get

9y-33+3y =27

Condense variables

12y-33=27

add 33 to each side

12y= 60

Divide by 12

y = 5

Plug into one of the original equations (I will be doing both to show it doesn't matter what equation you use, but you only need to use one equation, I personally think it is easier to plug into the second equation)

Equation 1: 3x+3y=27

Plug in what we got for y

3x+3(5)=27

multiply

3x+15=27

subtract 15 from each side

3x=12

divide by 3

x=4

Equation 2: x-3y = -11

Plug in what we got for y

x-3(5) =-11

Multiply

x-15= -11

Add 15 to each side

x=4

Answer:

n = -11

Step-by-step explanation:

3n - 17 = -50

⇒ 3n = -33

⇒ n = -11

Answer:

n = -11

Step-by-step explanation:

3n - 17 + 17 = -50 + 17

3n = -33

3n/3=-33/3

n = -11

Answer:

Answer: x = 1 and y = 2

Step-by-step explanation:

Solve for y in the first equation by adding 2x to both sides

[tex]y=2x[/tex]

Then plug this in for the y value in the second equation

[tex]3x+4(2x)=11[/tex]

Combine like terms and simplify

[tex]3x+8x=11\\11x=11\\x=1[/tex]

Plug x into either equation to find the y value

[tex]y=2x\\y=2(1)\\y=2[/tex]
