Find The Value Of X.
Answer:
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
x=25.5

You buy a carton of milk and two sandwiches for $10.One sandwich costs twice as much as a carton of milk.Your friend buys two cartons of milk and three sandwiches. How much does your friend spend?
The total amount spent by your friend is $8
How to determine the amount spent by your friend?The given parameters are:
1 carton of milk and 2 sandwiches= $10The cost of 1 sandwich = Twice carton of milkRepresent sandwich with x and carton of milk with y
So, we have
x = 2y
This also means that
y + 2x = 10
Substitute x = 2y in y + 2x = 10
y + 2(2y) = 10
This gives
5y = 10
Divide by 2
y = 2
Recall that:
x = 2y
So, we have
x =2 * 1
x = 2
Your friend's purchase can be represented as:
2y + 3x
This gives
Total = 2 * 1 + 3 * 2
Evaluate
Total = 8
Hence, the amount spent by your friend is $8

A parking lot has 65 spaces total. If 30 of the spaces have cars in them, what is the ratio of empty spaces to filled spaces?
Answer: 35:30, because 65-30 equals 35 and if you do the empty spaces which there are 35 to the filled spaces which there are 30 it will become your answer of 35:30.
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
Hence , The ratio of the empty spaces to the filled spaces is 7 : 6

How do you solve for x if x/5 = 7/3
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.

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.
Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross.A line that intersects both the parallel lines is called a transversal.A set of angles on the inner side of each of the two lines but on the opposing sides of the transversal are known as alternate interior angles.Alternate external angles are those outside the two lines that the transversal is intersecting.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.

Debbie has 340 dimes in three boxes. she says that there are 4 times as many dimes in the first box as in the second and 3 times as many in the third box as in the first how much money in dollars does she have in each box
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
Solving equationsFrom 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

Consider the line y=

What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
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]).
Equation: An equation is a mathematical statement that consists of two separate expressions, connected by an equal signSlope: Slope of a line is defined as the inclination of the line along the positive (x- axis) and is calculated by the formula [tex][m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}} ][/tex] where (x₁, y₁) and (x₂, y₂) are two points on the line.To learn more about Slopes (of Lines), click on the link below.
