Answer:

Step-by-step explanation:

(x + 2) ÷ 2 + (x + 4) ÷ 4 = 4

lcm is 6

(x + 2) ÷ 2 × 6 + (x + 4) ÷ 3 × 6 = 4

(x + 2) × 3 + ( x + 4) × 2 = 4

3x + 6 + 2x + 8 = 4

correct like terms

3x + 2x + 6 + 8 = 4

5x + 14 = 4

5x + 14 - 14 = 4 - 14

5x = - 10

5x ÷ 5 = -10 ÷ 5

The temperature was -2°F in the afternoon and is now -30°F. How many degrees did it drop?

Answers

Answer:

28°

Step-by-step explanation:

Let's take 'x' as the number of how much degrees it dropped. So this is how the equation will look like:

-2 - x = -30

It is '-x' since the temperature 'decreased', so you must a subtract.

Take -30 to the other side and substitute it with '-x'. Since both the terms are shifted, -30 will be +30 and -x will be +x (which is equivalent to x).

x = -2 + 30

x = 28°

∴ There was a 28° drop.

Work out the equation of the line which has a gradient of 1/2 and passed through the point (4,-2)

Answers

Answer:

2y-x = -8

Step-by-step explanation:

The equation if a line ilin point slope form is expressed as;

y-y0 = m(x-x0)

M is the slope

(X0,y0) is the point

Substitute

y - (-2) = 1/2(x-4)

y+2 = 1/2(x-4)

2(y+2) = x-4

2y+4 = x-4

2y-x = -8

Hence the required equation is 2y-x = -8

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

We are given that grocery store sells a bag of 7 oranges for $4.48. If Khloe spent $6.40 on oranges, then

We have to do as $4.48 divide by 7

4.48 / 7 =  $0.46

Therefore, Each orange costs $0.64

For 10 oranges;

$0.46 x 10 = $6.40

What is expression?

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given expression as :

⇒ m + 5q

where m = 1, and q = 5

Substitute the values of m = 1, and q = 5 in the expression and apply the arithmetic operations

⇒ 1 + 5(5)

⇒ 1 + 25

⇒ 26

Hence, the solution of m + 5q is 26, where m = 1, and q = 5.

Write an equation in slope-intercept form from the points (0, 3) and (-4,-1)

Answers

Answer:

y = x + 3

Step-by-step explanation:

Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. We can write an equation in point-slope form first, then convert it to that form.

1) First, find the slope of the line. Use the slope formula  [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] and substitute the x and y values of the given points into it. Then, simplify to find the slope, or [tex]m[/tex]:

[tex]m = \frac{(-1)-(3)}{(-4)-(0)} \\m = \frac{-1-3}{-4-0} \\m = \frac{-4}{-4} \\m = 1[/tex]

Thus, the slope of the line must be 1.

2) Now, since we know a point the line intersects and its slope, use the point-slope formula [tex]y-y_1=m(x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex]. From there, we can convert the equation into slope-intercept form.

Since [tex]m[/tex] represents the slope, substitute 1 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

[tex]y-3=1(x-0)\\y-3 = x\\y = x + 3[/tex]

The ratio or the relationship of the toy to the large building is one foot to every 400 feet so in mathematical terms it’s shown as a ratio like this... 400:1 and since they are asking about the real building as the primary reason for the ratio it’s number goes first because they are enquiring about it’s relationship to the small one.(which is worded weirdly so I think they are trying to get you messed up)

Answer: attending the game

Step-by-step explanation:

Given: 12 out of the first 48 people who entered the stands were wearing a coat.

That means, Proportion of people wearing coat = [tex]\dfrac{12}{48}=\dfrac{1}{4}[/tex]  (People wearing coat divided by Total people)

Total people in the sample attending the game= 200

Women would seem to be unfitted physically to engage in them. But do we find a corresponding mental or moral disability? On the contrary, instances are by no means uncommon of the natural taste of a woman leading her so decidedly to one or other of these professions that she has overcome all obstacles and actually engaged in them. Disguised as men, women have more than once been detected as soldiers and sailors, some having performed their duties creditably, and maintained the secret of their sex for years. We may assume that all have not been detected, and that a careful scrutiny might possibly reveal others scattered among the ships and armies of the world. These instances are not adduced with a view of proving that it is desirable to open such professions to women, but merely in support of my proposition that sex does not extend to mind. As these military and naval heroines were feminine in body they would have had minds to correspond if it were truly a law of nature that there was such a thing as sex in taste and intellect.Needlework is a trade seemingly peculiarly adapted to the powers and tastes of women. Yet surely it is not hard necessity which leads so many men to embrace it. Men can do it, and do it well, and as there is no legal nor social restraint on them, they set to work to make clothes, I presume with satisfaction to themselves, as well as to those who employ them.Many professions are common to both sexes; and the votaries* of art and literature are taken from the ranks of men and women indiscriminately, though the opportunities of study and the prospect of reward are greatly in favour of the dominant sex.If we take an assemblage of persons of opposite sexes and test the difference of thought and opinion existing among them by putting before them any proposition on which opposite views can be held, I believe it would be impossible to find one which would range all the men on one side, and all the women on the other. If it were true that there is a specific difference, however slight, between the minds of men and women, it would be possible to find such a proposition, if we took one which corresponded to this distinction. When a naturalist seeks to group a number of individuals into a distinct class, he fixes on some character, or set of characters, common to them all, and distinguishing them from other individuals. When he finds such a group distinctly defined he calls it a species. But when he finds two individuals differing very widely from each other, yet so connected by numerous intermediate forms that he can pass from one extreme to the other without a violent break anywhere in the series, he considers them to be of one and the same kind. Taking the conventional masculine type of mind as one end of the scale, and the conventional feminine type as the other, I maintain that they are connected by numerous intermediate varieties distributed indiscriminately in male and female bodies; that what is called a masculine mind is frequently found united to a feminine body, and sometimes the reverse; and that there is no necessary, nor even presumptive connexion between the sex of a human being, and the type of intellect and character he possesses.The authors statement that instances are by no means uncommon (paragraph 2, sentence 4) contributes to a tone that is?a)defensive and indignantb)poetic and evocativec)brusque and dismissived)plainspoken and directe)measured and objective answer and how so? have a good day/night/afternoonnn In which region of North America did the Great Awakening begin?A: the SouthB: the MidwestC: New England D: the Pacific Northwest A truck that is 10 ft. by 12 ft. by 8 ft. carries cube shaped boxes that have alength of 1.5 ft.
