What is subtraction?

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol - , or, denotes subtraction. For instance, in the following image, there are 5 2 peaches, which means that 5 peaches have had 2 removed, leaving a total of 3 peaches.

Given Data

The record high temperature on January 15 is 41.5 Fahrenheit the record low temperature on that day is -16.8.

Difference = High temperature - Low temperature

Difference = 41.5 -(-16.8)

Difference = 41.5 + 16.8

Difference = 58.3

The difference in the record temperatures is 58.3° Fahrenheit.

Could you please set it up in the form of "systems of equations" meaning, set to different equations with "x" and "y" ??
That is what they want me to do in class.

Answers

There are various types of equation systems, including linear, non-linear, and multiple or single-variable systems.

Explain the System of equations?

A set of two linear equations with two variables is a system of linear equations.

ax + by = C

A set of two or more equations in two or more variables that includes at least one nonlinear equation is referred to as a system of nonlinear equations. A nonlinear equation can be written as ax+by+C≠0 or ax + b y + C ≠0.

The equation for a linear equation in one variable is written as ax+b = 0, where a and b are two integers, and x is a variable. This equation has only one solution.

B) The equivalent expression to 3(−4.5b − 2.1) − (6b + 0.6) is - 19.5b - 6.9

How to simplify Algebraic Expressions?

A) We want to simplify negative one eighth j plus two thirds minus the expression five thirds j plus nine twelfths. This would be expressed as;

-1/8j + 2/3 - (5/3j + 9/12)

= -1/8j + 2/3 - 5/3j - 9/12

= -1/8j - 5/3j + (2/3 - 9/12)

= (-3j-40j / 24 + (8-9) / 12

= [-⁴³/₂₄j + (-1)]/12

B) The expression equivalent to 3(−4.5b − 2.1) − (6b + 0.6)

Expand the brackets to get;

A jet’s speed in still air is 240 mph. One day it flew 700 miles with a tailwind (the wind pushing it along) and then returned the same distance against the wind. The total flying time was 6 hours. Find the speed of the wind.

Answers

Speed of the wind for jet speed in still air 240mph and jet covers 700 miles with tailwind and same distance against the wind in total time of 6 hours is equal to 40mph.

As given in the question,

Given data:

Jet speed in still air = 240mph

Let x be the speed of the wind.

Speed with tail wind = 240 +x

Distance covered with tail wind = 700miles

Time taken by jet with tail wind

= Distance/ speed

= 700 / (240 +x)  __(1)

Speed against the wind = 240 - x

Distance covered against the wind = 700miles

Time taken by jet against the wind

= Distance/ speed

= 700 / (240 - x)  __(2)

Total time taken is 6 hours

[700 / (240 +x)] + [700 / (240 - x)] = 6

⇒ 700( 240 -x + 240 + x) = 6 (240 +x)(240 - x)

⇒ 700 ( 480) = 6 ( 240² -x²)

⇒ 700 (80) = 57600 -x²

⇒ x² = 57600 - 56000

⇒ x² = 1600

⇒ x = √1600

⇒ x= 40 mph

Therefore, speed of the wind for jet speed in still air 240mph and jet covers 700 miles with tailwind and same distance against the wind in total time of 6 hours is equal to 40mph.

A diagram of the side of Robert's barn is shown. If he decides to paint one side of the barn, how many square feet will Robert paint?

1. 254.5 ft^2
2. 310.5 ft^2
3. 391 ft^2
4. 805 ft^2

Answers

Robert will paint 310.5 square ft

The side of Robert's barn contains a triangle and a rectangle of which the dimensions are given in the diagram.

If Robert paint one side of the barn, then he needs to paint the triangle as well as the rectangle. So we need to find the area of the triangle and rectangle first.

For the triangle, base = 23 ft

height = 7 ft

Area of the triangle = 1/2 bh

                                 = 1/2 x 7 x 23

                                 = 80.5 square ft.

For the rectangle, length = 23 ft

width = 10 ft

Area of the rectangle = length x width

                                    = 23 x 10

                                    = 230 square ft.

Area Robert needs to paint = Area of the triangle + Area of the rectangel

                                              = 80.5 + 230

                                              = 310.5 square ft.

C>0, |u|=c is equivalent to u=

Answers

|u|=c is equivalent to u = c or u = -c.

Given that c > 0.

i.e., c is a positive number.

Then |u| = c. That is, absolute value of u = c, a positive number.

An absolute value function is defined by,

 |u| = { u   ; if u ≥ 0

        { -u   ; if u < 0

The absolute value of any number, Positive or negative, is always a positive number.

So here |u| = c, with c > 0.

Comparing with the definition of absolute value function, c is either u or -u.

More clearly, c = u, when u ≥ 0 or c = -u , when u < 0.

Hence the value of c depends on u.

Thus,  |u|=c is equivalent to u = c or u = -c.

(Round your answers to three decimal places.)

Answers

Using the binomial distribution, the probability of no one having done a one time fling is of 0.735 = 73.5%.

Binomial distribution

The mass density formula for the probability of x successes is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters of the formula are given as follows:

n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.

In the context of this problem, the values of the parameters are as follows:

p = 0.05, as about 5% of all adults deliberately do a one-time fling and feel no guilt about it.n = 6, as there are six adult friends in the group.

The probability that no one has done a one time fling is P(X = 0), hence the probability is calculated as follows:

P(X = 0) = (0.95)^6 = 0.735 = 73.5%.

Write a system of equations that represent the graph .

Answers

To write an equation for the lines of the graph, we have to find the slope and the y-intercept of each line.

The y-intercept can be find as the value of y when the line intersects the y-axis.

For company L, that intersects at (0,10), the y-intersect is y(0)=10.

For company K, that intersects at (0,5). the y-intersect is y(0)=5.

The slope can be find using two points of the line.

For Company L we will use points (0,10) and (20,15). Then, we calculate the slope as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{15-10}{20-0}=\frac{5}{20}=0.25[/tex]

For Company K, the points will be (0,5) and (20,15), and the slope will be calculated as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{15-5}{20-0}=\frac{10}{20}=0.5[/tex]

With the slope and y-intercept we can write the equation of each line in slope-intercept form.

For Company L, with slope m=0.25 and y-intercept b=10 we will have:

[tex]\begin{gathered} y=mx+b \\ y=0.25x+10 \end{gathered}[/tex]

For Company K, with slope m=0.5 and y-intercept b=5, we will have:
