Answer:

6x+8

Step-by-step explanation:

38 inches. We write an equation for how much it grows each year, plus the original 8 inches. So, 6(5)+8=38

Answer:

Westbound = x;

Eastbourne = x-20;

So they will have the common rate: 360/2 = 180;

x+x-20 = 180

2x = 200;

x = 100;

So Eastbourne will be 100-20 = 80 miles per an hour;

Answer:

The amount of fabric needed to create one quilting square is 8 inches.

Step-by-step explanation:

The solution to the original equation is 1, 1/6

Equations are expressions separated by mathematical operations.

Given the equation below

x/x − 1 = 6x + 1/x − 1

From the given expression, the least common denominator is x -1

Multiply both sides by x-1 to have;

x = 6x(x-1) +1

Expand

x = 6x^2-6x + 1

Equate to zero

6x^2-6x-x + 1 = 0

6x^2-7x +1= 0

The resulting quadratic equation in general form is 6x^2-7x +1 = 0

Factorize

6x^2 -6x-x + 1 = 0

Group the result

6x(x-1)-1(x-1) = 0

(6x-1)(x-1) = 0

6x - 1 = 0 and x -1 = 0

x = 1 and 1/6

Hence the solution to the original equation is 1, 1/6

Answer:

6w + 2a = 28

Step-by-step explanation:

the expression given, 6w + 2a, contains no variable h, so it's best to just ignore that h = 5.

first, plug in the values for w and a. you can do this in whatever order you want, but i'll start with w for this example.

plug in 4 for w.

6w + 2a

6(4) + 2a

now plug in 2 for a.

6(4) + 2a

6(4) + 2(2)

after plugging in the values, your expression is 6(4) + 2(2).

all that's left is to simplify. again, this can be done in whatever order you prefer, but i'm going to start with 6(4).

6(4) + 2(2)

24 + 2(2)

continue simplifying by multiplying 2(2).

24 + 2(2)

24 + 4

now add 24 + 4.

24 + 4 = 28

so, when w = 4 and a = 2, 6w + 2a = 28.

you can check the answer by plugging those values for a and w back into the completed equation.

6w + 2a = 28

6(4) + 2(2) = 28

24 + 4 = 28

28 = 28

since both sides of the equation are equal, that means that your answer of 28 is correct! :)

For Marvin used the Quantitative Reasoning Process to build a budget while he is going to college. He worked hard over the summer and saved $2,595.9 to live on during the next two semesters of school. Marvin will receive a scholarship each semester for $958.35 money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items is mathematically given as  

$4512.6

Savings with Marvin = $2,595.9

Scholarship amount  = $958.35

Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7

Now total money that Paolo have = (Savings with Marvin) + (Total Scholarship amount received in both semesters) = $2,595.9 + $1916.7 = $ 4512.6

Tuition & books cost  = $2000

Tuition & books cost for 2 semesters = $2000 X 2 = $4000

Housing cost for 2 semester contract =$1,000

Total expenses in books and housing = $4000+ $1000 = $5000

Money left with Marvin after Total expenses in books and housing = $ 4512.6 - $5000 = −487.4

This means he has overspent.

as no. of months in 2 semesters = 8

Amount that Marvin would be in debt each month = −487.4/8 = −$60.925

Step-by-step explanation:

We can see that lines AB and CD intersect at pοint P, and they are nοt perpendicular. Therefοre, sentence D is true.

The Cartesian plane, alsο knοwn as the cοοrdinate plane, is a twο-dimensiοnal plane used tο represent pοints, lines, and shapes in geοmetry.

answer is (2,-4)

Step-by-step explanation:

I did it's process in next question

Answer:

We can use the formula for compound interest to solve this problem. The formula is:

A = P * (1 + r/n)^(n*t)

where:

A = the amount of money after t years

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $5000, r = 0.03, n = 12 (since the interest is compounded monthly), and t = 10. Plugging these values into the formula, we get:

A = 5000 * (1 + 0.03/12)^(12*10)

A = 5000 * (1.0025)^120

A ≈ $6,621.36

So the investment will be worth approximately $6,621.36 after 10 years.

Answer:

3 formas

Step-by-step explanation:

Se nos pide que averigüemos cuántas formas puede utilizar para cruzar un río si tiene 1 bote y 2 barcos

Número total de barcos = 3 barcos.

Resolvemos esto usando la regla de combinación.

C (n, r) = nCr = n! / R! (n - r)!

n = Número de barcos = 3

r = Número de ríos = 1

3C1 = 3! / 1! (3 - 1)!

= 3! / 1! × 2!

= 3 × 2 × 1/1 × 2 × 1

= 3 formas.

Por lo tanto, el número de vías por las que puede cruzar un río utilizando 1 bote y 2 barcos es de 3 formas.

If the function is:

\(x=4,\\y=8\)

Step-by-step explanation:

Notice that in the diagram, opposite sides are equal. This is true for any rectangle, so even without the equal sides being marked, we'd know that each pair of opposite sides have the same length.

Therefore, we can set up the following equations and solve for \(x\) and \(y\):

\(2y=y+8,\\y=\boxed{8}\)

\(4x-8=2x,\\-8=-2x,\\x=\boxed{4}\)

The percentage of students who do not walk to class and do not have a lunchbox is 28.25 %.

From the illustration:

Total number of students = 400

Number of students that do not walk and do not have a lunchbox = 113

Percentage component = number of component/total number x 100

Thus:

Percentage of students who do not walk to class and do not have a lunchbox:

  = 113/400 x 100%

  = 28.25 %

To the nearest hundredth = 28.25%

In other words, the percentage of students who do not walk to class and do not have a lunchbox is 28.25%.
