Step-by-step explanation:

8(x−4)+19=8x−13

Step 1: Simplify both sides of the equation.

8(x−4)+19=8x−13

(8)(x)+(8)(−4)+19=8x+−13(Distribute)

8x+−32+19=8x+−13

(8x)+(−32+19)=8x−13(Combine Like Terms)

8x+−13=8x−13

8x−13=8x−13

Step 2: Subtract 8x from both sides.

8x−13−8x=8x−13−8x

−13=−13

Step 3: Add 13 to both sides.

−13+13=−13+13

0=0

Answer:

4.9

Step-by-step explanation:

Plug in 13 and 2 for each variable separately to get 0.7(13) - 2.1(2).  0.7 multiplied by 13 equals to 9.1 and 2.1 multiplied by 2 equals 4.2.  Subtract 4.2 from 9.1 to get your final answer which is 4.9.

Answer: 2 rational solutions

Step-by-step explanation:

When the discriminant,  b² + 2a,  is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7

When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. Type of solutions the quadratic equation will have Two Real Rational Solutions.

Discriminant is a number that can be calculated from any quadratic equation.

What is quadratic equation?

A quadratic equation is an equation that can be written in the form of [tex]ax^2+bx+c[/tex]  (where[tex]a\neq 0[/tex]).

Formula for the Discriminant [tex]=b^2-4ac[/tex]

Also,

If Discriminant is Positive and perfect square then quadratic equation will have Two Real Rational Solutions.

We have,

Discriminant [tex]=49[/tex]

So,

We have Discriminant which is a positive number and also it is a perfect square. That means quadratic equation will have Two Real Rational Solutions.

Hence, we can say that When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. Type of solutions the quadratic equation will have Two Real Rational Solutions.

Answer:

30

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

6/0.20 = 30.

Since to Normally find a percentage of a number, you would Multiply the percentage in decimal form, multiplied times the full amount, to get a percentage. ( 30*0.2 = 6)

So to find the full amount (in this case of students) Reverse this process, and divide the Portion by the percentage (In this scenario, 6/0.20) and you will get the full amount.

Answer:

  316 m²

Step-by-step explanation:

The centerline length of the walkway is 2×(52 m +27 m) = 158 m.

The area is the product of the walkway's centerline length and its width:

  A = (158 m)(2 m) = 316 m²

_____

More detail on this approach

The centerlines of the long-side walkways are 25 m + 1 m + 1 m = 27 m apart. The centerlines of the short-side walkways are 50 m + 1 m + 1 m = 52 m apart.

The total length of the centerline is the perimeter of a 27 m by 52 m rectangle:

  P = 2(L+W) = 2(52 m +27 m) = 158 m

_____

Usual approach

The area with the walkways is 54 m by 29 m = 1566 m². The area without the walkways is 50 m by 25 m = 1250 m². The difference is the area of the walkway, 1566 -1250 = 316 square meters.

Step-by-step explanation:

Given:

Total number of student = 54,000

Growth rate = 1.2% each year

Find:

Total number of student next year

Computation:

Total number of student next year = Total number of student(1+Growth rate)

Total number of student next year = 54,000(1+1.2%)

Total number of student next year = 54,648

Brewed coffee      Hot             4                    0                        260

Caffè latte              Hot            100                  14                      75

Caffè mocha          Hot               170                 27                      95

Iced brewed coffee Cold        60                 15                         120

Chai latte              Hot            120                 25                       60

The individuals in this data set are:

1) Ben Bean's  customers

2) Ben Bean's drinks

3) Caffeine Contents

This is a list of the coffee drinks not customers so option 2 is correct. Nor it deals with caffeine content.

The data set contains

1) 4 variables, of which 1 is categorical

2) 4 variables , of which 2 are categorical

3) 6 variables , of which 1 are categorical

4)  6 variables , of which 2 are categorical

Here option1 is correct because we have 4 variables ( type, calories, sugar, caffeine)out of which 1 ( type) is divided into 2 categories (hot or cold).

Answer:

#of blocks in a single layer of the wall * 3(x)-9/4

Step-by-step explanation:

So, let Y be the length of the wall. It will be made from the building blocks described.

If the perimeter of a square block is 12x-9 and the formula for the perimeter of a square is 4s (where s = length of a side). Then one side of the square is the perimeter divided by 4.

s = (12x-9)/4 = 3x-9/4

In order to find the length of the wall, multiply s by the number of blocks used to build one level of the wall.

The length of the wall is  n×(3x-9/4)

The perimeter of a square is defined as the length that its boundary covers. The formula to calculate the perimeter of a square is given as: P = 4 × side.

Given:

The perimeter of the square base = 12x-9 inches

As we know the Perimeter of the square = 4×side

Equating both we get

4× length of the square base = 12x-9

length of the square base = (12x-9)/4

length of the square base = 3x-9/4 inches

and depending on the number of blocks say n the length of the wall will be = n×(3x-9/4)

Hence the length of the wall =  n×(3x-9/4)

Answer:

$20,000 = sales

Step-by-step explanation:

Giving the following information:

Fixed salary= $300

Commission rate= 1% of sales

First, we need to establish the net income formula:

Net income= 300 + 0.01*sales

Now, the sales required for $500 net income:

500= 300 + 0.01sales

200/0.01 = sales

20,000 = sales

Prove:

Net income= 300 + 0.01*20,000

Net income= $500

Step-by-step explanation:

To compute a log that doesn't have a base of 10 you use the following formula

Log(number)/Log(base)

We can use this formula to compute the numbers with no variables

Log₃18= Log(18)/log(3) which gives us around 2.63

We can then compute the first part of the right side 2*log₃6 which can be rewritten as 2*(log(6)/log(3)) which gets us around 3.26

After computing this we can rewrite it all as 2.63=3.26-(.5*log₃x)

This is pretty easy to solve from here and we start by subtracting 3.26 from both sides which gives up

-.63=.5*log₃x

Dividing both sides by negative one half (or .5) gives us

1.26=log₃x

You then can use a special rule to rewrite this equation

3^1.26=x

This gives us 3.99 which is pretty much 4
