Therefore, the value of "s" that satisfies the given equation three more than the difference of 6s and 5s is equal to the sum of 12 and 6. is 15/4.

A linear equation is one where the variable's maximum power is 1. To put it another way, a linear equation is one that has the form axe + b = 0, where a and b are constants and x is the variable.

The speed of an item travelling straight forward or the pace at which a population is increasing are two examples of real-world scenarios that are equal to the frequently modelled using linear equations. They are rather easy to resolve, and the answers may be obtained by applying fundamental algebraic strategies such isolating the variable and running calculations on both sides of the problem.

In several disciplines, including physics, engineering, and economics, linear equations are used extensively.

How to solve?

Let "s" be the unknown value that we are trying to find.

3 + (6s - 5s) = 12 + 6

3 + (6s - 5s) = 12 + 6

3 + 1s = 18

4s = 15

Answer:

x<5

Step-by-step explanation:

2x-7+3x+10>x-6+8x-11

5x+3>9x-17

5x-9x>-17-3

-4x>-20

x<5

Answer:

x < 5

Step-by-step explanation:

step 1: simplify both sides of the inequality.

5x + 3 > 9x − 17

step 2: subtract 9x from both sides.

5x + 3 − 9x > 9x − 17 − 9x − 4x + 3 > − 17

step 3: subtract 3 from both sides.

−4x + 3 − 3 > − 17 −3 − 4x > − 20

step 4: divide both sides by -4.

-4x/-4 > -20/-4

x < 5

The equation (7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07 can be rewritten as:

7x + 0.7y + z = 700 070.07

To find a set of values for x, y, and z that satisfies this equation, we can use trial and error. One possible set of values is:

x = 100

y = 10

z = 7000

If we plug these values into the equation, we get:

(7 × 100) + (7 × 0.1) + (7 × 7000) = 700 070.07

Which simplifies to:

700 + 0.7 + 49000 = 700 070.07

This equation is true, so the values x = 100, y = 10, and z = 7000 are a solution to the original equation.

Given that the first two sides of a triangle are 8 cm and 10 cm in length, the third side's range of potential lengths will be [2,18].

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself. The difference between the highest and lowest values for a given data collection is the range in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range can also be thought of as the distance between the highest and lowest observation.

Here,

The minimum length can be,

=10-8

=2 cm

The maximum length can be,

=10+8

=18 cm

(10-8)<x<(10+8)

2<x<18

Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.

Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.

The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.

\text{Function Rule:}

Function Rule:

V(x)=7x

V(x)=7x

Plug x=11 Into Rule:

V(11)=7(11)=77

Correct Answer:

The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.

A function relating these variables is V(x) =V(x)= 7x7x.

So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test

EV = - + prob(win)*win

= -5 + 1/1000 * 375

=  -4.62

The requried, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.

To calculate the expected value, we need to consider the probability of winning the color television and the corresponding value of the prize. We can then subtract the cost of buying the ticket to find the expected value.

Given:

Cost of one ticket = $5

Value of the color television (prize) = $375

Number of tickets sold = 1000

The probability of winning the color television is 1 out of 1000, as only one ticket will be selected out of the total 1000 tickets sold.

Expected Value (EV) = (Probability of winning * Value of prize) - Cost of the ticket

EV = (1/1000 * $375) - $5

EV = $0.375 - $5

EV = -$4.625

Rounded to two decimal places, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.

The dimensions of the classroom are a width is 5 m and a length is 9 m.

We have been given that the width of a classroom is 4m less than the length its area is 45m², then.

L= 4 + W

Area = 45, so

L x W = 45

Now substituting the value of L, we get.

(4+W) W=45,

Now simplifying this we get.

4W + W² =45

W² + 4W - 45 = 0, this is a quadratic equation

Now solving this we get the factors 9 and -5,

(W+9) and (W-5) = 0

Thus, W= -9 or W= 5, since the width cannot be negative,  

So, it is width = 5

So, length = 9 m

In physics and arithmetic, the dimension of a mathematical space (or item) is informally defined as the minimal range of coordinates to specify any factor within it. therefore, a line has a dimension of one (1D) due to the fact handiest one coordinate is wanted to specify a factor on it – for instance, the point at 5 on more than a few lines. A floor, together with the boundary of a cylinder or sphere, has a size of two (2d) because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the floor of a sphere. A two-dimensional Euclidean area is a -dimensional area on the aircraft. The internal of a dice, a cylinder, or a sphere is 3-dimensional (3-d) due to the fact 3 coordinates are had to find a factor inside these spaces.
