Step-by-step explanation:

This is a fraction equal to

455 miles ÷ 7 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 7

455 miles ÷ 7

7 hours ÷ 7

=

65 miles

1 hour

=

65 miles

= 65 miles per hour

Assuming that f(x)=x, we need to shift f(x) to the left by 5 and up by 2 in order to get g. (x). The equation g(x) may be written in mathematical terms as

G(x)=(x+5)+2

This is further explained below.

Generally, In the field of mathematics, an assignment of one element from set Y to each and every element in set X is the definition of a function. This particular set, X, is referred to as the function's domain, and this particular set, Y, is referred to as the function's codomain.

In conclusion, Assuming f(x)=x, f (x) is shifted left 5 and shifted up 2 to create g(x).  the equation g(x) is mathematically given as

G(x)=(x+5)+2

Answer:

x would equal -1.03(1 DP)

"-26x - 12 = 15, solve for x."

Step-by-step explanation:

Start with adding 12 to both sides of the expression. Sides were switched purposely.

[tex]15 + 12 = -26x - 12 + 12[/tex]

Next, simplify your addition process. You do this by using a specific rule.

[tex](-a) = a\:\:\mathrm{if\:a\neq 0}\\-26x = 26x\\26 + (x)\\= 26 + 1\\= 27\\= -26x=27[/tex]

Lastly, we are going to divide both sides by -26(x was cancelled).

[tex]\frac{-26x}{-26}=\frac{27}{-26}[/tex]

Thus,

[tex]x= -1.03[/tex]

➲ Hope this helps, address any concerns if needed.

Answer:

x = -1.038

Step-by-step explanation:

- 26x - 12 = 15

- 26x = 15 + 12

- 26x = 27

x = - 27/26

x = - 1.038

From properties of parallel lines the value of the indicated angle is 84° and the value of x is 4°.

Parallel lines are two lines that are equidistant from one another.

For the question 7 the two lines are parallel and the indicated angle is an alternate interior angle to the given angle. Hence the indicated angle is also 84°.

For question 8, the two angles are alternate exterior angles.

Hence they are equal. Therefore we can write a linear equation in x to solve for x.

The least Andrew's average could possibly be when he goes up to bat the tenth time of the series is 0.399.

Here, we are given that,

Andrew's batting average = 0.400

Number of career hits for 0.400 batting average = 2000

Previous bat times for 0.400 batting average = 5,000

Now,

For the least possible average, he must have zero career hits in every match he bats.

Before the tenth time of the series, he will bat in 9 times

He must have 0 career hits in these 9 matches he bats in

therefore,

The total number of career hits = 2000

Total number of bat times = 5,000 + 9 = 5,009

Hence,

Average = (Total career hits) ÷ (Total number of times he bats)

= 2000 ÷ 5,009

= 0.399

Thus, the least his average could possibly be when he goes up to bat the tenth time of the series is 0.399.

X=25.5

Step-by-step explanation:

First we need to apply supplementary angles.

We see that angle EGH is 78 degrees. Since Angle BEC falls on the same line as EGH we can easily calculate the Angle for BEC

Supplementary angles add up to 180. 78+x=180

180-78 is 102

4x=102

divide both sides by 4

If the equation of a line is [y = (12x + 2)], then the slope of a line parallel to this line will be (Tan θ = 12) and, slope of a line perpendicular to this line will be [Tan θ = [tex](\frac{-1\1}{12})[/tex]].

As per question statement, the equation of a line is [y = (12x + 2)].

We are required to find out the slope of a line parallel to this line and the slope of a line perpendicular to this line.

To solve this question, firstly, we need to know about the standard equation of a line which goes as [tex][y = (mx +c)][/tex] where, "m" is the slope of the line and "c" is the y-intercept.

Comparing our given equation [tex][y = (12x +2)][/tex] with the above mentioned standard equation of [tex][y = (mx +c)][/tex], we get (m = 12) and (c = 2).

Hence, slope of our concerned line is 12. And since slopes of all parallel lines are equal, therefore, the slope of any line parallel to the line [tex][y = (12x +2)][/tex] will be 12 or (Tan θ = 12).

Also, we know that, the product of the slopes of two perpendicular lines, (say m₁ and m₂) is equal to (-1), i.e., [m₁*m₂ = (-1)].

Therefore, the line perpendicular to [tex][y = (12x +2)][/tex] will have a slope of [tex](\frac{-1}{m})[/tex], i.e., ([tex]\frac{-1}{12}[/tex]).

The amount of money in the first box is 8 dollars

The amount of money in the second box is 2 dollars

The amount of money in the third box is 24 dollars

From the question, we are to determine how much money there are in each box

From the given information,

"Debbie has 340 dimes in three boxes"

Let x represents the number of dimes in the first box

y represent the number of dimes in the second box

and z represent the number of dimes in the third box

Thus,

x + y + z = 340

Also, from the given information

"she says that there are 4 times as many dimes in the first box as in the second"

x = 4y

and

"3 times as many in the third box as in the first"

z = 3x

Substitute the second and third equations into the first equation

x + y + z = 340

4y + y + 3x = 340

4y + y + 3(4y) = 340

4y + y + 12y = 340

17y = 340

y = 340/17

y = 20

Substitute the value of y into the second equation

x = 4y

x = 4(20)

x = 80

Substitute the value of x into the third equation

z = 3x

z = 3(80)

z = 240

Thus,

There are 80 dimes in the first box

80 dimes = 8 dollars

There are 20 dimes in the second box

20 dimes = 2 dollars

There are 240 dimes in the third box

240 dimes = 24 dollars

Hence,

The amount of money in the first box is 8 dollars

The amount of money in the second box is 2 dollars

The amount of money in the third box is 24 dollars

Answer: most likely 2,2 I believe

Step-by-step explanation:

We get that, the value of x is 11.67 when the equation is x / 5 = 7 / 3.

An equation is a combination of two expressions connected by an equal sign.

We are given an equation:

x / 5 = 7 / 3

We need to find the value of x.

Multiply both sides by 5

x / 5  × 5 = 7 / 3 × 5

x = 35 / 3

Now, we will divide 35 by 3 and round off the result to two decimal places:

x = 11.67

Therefore, we get that, the value of x is 11.67 when the equation is x / 5 = 7 / 3.

Hope this helps!

The solution is 7 : 6

The ratio of proportion of the empty spaces to the filled spaces is 7 : 6

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the total number of parking spaces be = P

The value of P = 65 spaces

Now , the number of spaces that are filled with cars = 30 spaces

So , the remaining number of spaces = the empty spaces

The remaining number of spaces = total number of parking spaces - number of spaces that are filled with cars

Substituting the values in the equation , we get

The remaining number of spaces = 65 - 30

The remaining number of spaces = 35 spaces are empty

Now , the ratio of empty spaces to filled spaces is given by

Ratio of empty spaces to filled spaces = 35 : 30

On simplifying , we get

Ratio of empty spaces to filled spaces = 7 : 6

Therefore , the proportion is 7 : 6
