A linear equation in one variable is the equation that has one one term
How to explain a linear equation?You should understand that an equation is linear if there highest power of the equation is one (1)
The linear equation can have one or two terms. But in this regard, it the equation contains only a term or variable say x,y,m, p, q, a, b etc, the equation is said to be in one variable.
Taking the following sets of equations
x+4 = 5
2y-8=0
x+4=3-8x
These equations are linear and they contain only one variable.
Therefore, a linear equation is the equation containing one variable whose highest power of the variable is one.

The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13). The measures of the angles RIG and ZIM are 59° and 140°, respectively.
What are the variables behind a geometric system formed by three lines?
In this problem we find a geometric system generated by lines GZ, AM and IR, in which two variables are shown (x, z) and whose values can be found by applying the concepts of complementary and supplementary angles.
A group of angles are complementary if the sum of their measures equals 90°, and supplementary if that sum equals 180°. This system can be represented by the following system of linear equations:
(3 · x - 56) + 90 + (4 · z + 7) = 180 (1)
(4 · z + 7) + (x + 2) = 90 (2)
By (1):
(3 · x - 56) + (4 · z + 7) = 90
3 · x + 4 · z - 49 = 90
3 · x + 4 · z = 139 (1b)
By (2):
x + 4 · z = 81 (2b)
The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13).
Then, the measures of the angles RIG and ZIM are, respectively:
m ∠ RIG = 4 · z + 7
m ∠ RIG = 4 · 13 + 7
m ∠ RIG = 59°
m ∠ ZIM = 360° - (3 · x - 56) - 90° - (4 · z + 7) + (x + 2)
m ∠ ZIM = 360 - 3 · 29 - 56 - 90 - 4 · 13 + 7 + 29 + 2
m ∠ ZIM = 140°
The measures of the angles RIG and ZIM are 59° and 140°, respectively.

HELP!! PLEASE!! DUE!! TODAY!! Joanna's vegetable Garden covers an area of 1/6 of a square mile. if the garden is 1/4 mile wide, how long does the garden stretch?
The garden will stretch by 2/3 miles.
Given that Garden covers an area of 1/6 of a square mile and the garde is 1/4 mile wide.
As we know, the garden is a rectangle shape.
Here, we will use the formula of area of rectangle.
Area of rectangle is equal to the product of length and breadth.
Area =l×b
Here, the give area=1/6 miles² and b=1/4 mile.
Now, we will substitute the values in the formula, we get
1/6=l×(1/4)
Further, we will multiply both sides with 4, we get
4/6=4l/4
4/6=l
Now, we will simplify the left hand side, we get
2/3=l
Hence, the length of garden stretch when garden covers an area of 1/6 of a square mile and 1/4 mile wide is 2/3 mile.

180g = ___ kg
180g = 0.180 kg or there are 0.180 kilograms in 180 grams.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.
The sentence states an equality between a units of weight in grams (g) and kilograms (kg).
From there, we can say that we are asked how many kilograms are there in 180 grams.
Converting grams to kilograms, we must use the conversion

Solve: 5x - 7x + 6 = -2(x - 3).
A 0
B 3/4
C 2
D no solution
E infinitely many solutions
I will give 80 points
Answer: E: Infinitely many solutions
Step-by-step explanation:
Starting with 5x - 7x + 6, let's combine like terms.
5x - 7x is -2x.
Thus, we have -2x + 6 = -2(x-3)
Using the distributive property for the right side, we multiply -2 * x, and get -2x, and -2 * -3 and get +6.
Now we have -2x + 6 = -2x + 6. We have the same equation here, and know that there is infinitely many solutions here off the bat.
For sake of computations, let's solve and show our work.
Subtracting 6 from both sides, we have -2x = -2x.
Adding 2x to both sides, we get 0 = 0.
Thus, we have infinitely many solutions.

Bob is interested in examining the relationship between the number of bedrooms in a home and its selling price. After downloading a valid data set from the internet, he calculates the correlation. The correlation value he calculates is only 0. 5. What does bob conclude?.
According to the calculations made by Bob after downloading and calculating the correlation value as 0.5 from a given data set, he concludes that as the number of bedrooms in a particular home increase there is an increase in the selling price of the bed.
This increase in the selling price due to the increase in the number of bedrooms can be explained with the help of the Law of Demand which states that as the demand for a certain product increases its cost or the selling price also increases.
Thus, when Bob calculates the correlation factor, he finds that as the number of bedrooms increases there is also a hike in the selling price. As there should be a surplus to fulfill the demand for bedrooms.

of <2 is six more than twice the

The measure of the angle 2 is 122°.
What is referred as the linear pair?When lines intersect at a single point, a linear pair of angles is formed. If the angles are adjacent to one another after the two lines intersect, they are said to be linear. The sum of the angles of the a linear pair will always be 180°. These angles are also referred to as supplementary angles.Given that angles 1 and 2 form a linear pair,
angle 1 + angle 2 = 180 degrees —— (1)
We've also been notified that angle 2 is 6 times the size of angle 1.
That is to say: angle 2 = (2×angle 1) + 6 ———- (2)
Putting the angle 2 value in (1) from (2)
180 = angle 1 + 2×angle 1 + 6
3×angle 1 = 174
1st angle = 58 degrees ———-(3)
(1) and (3) come from:
angle 2 + 58 = 180
2nd angle = 122 degrees
As a result, angle 2 has a measure of 122 degrees.

If m< ABF=7b-24 and m< ABE = 2b, find m< EBF .
Answer:
∠ EBF = 16°
Step-by-step explanation:
note that EB is the angle bisector of ∠ ABF , then
∠ ABE = ∠ EBF = 2x and
∠ ABF = ∠ ABE + ∠ EBF , that is
7b - 24 = 2b + 2b
7b - 24 = 4b ( subtract 4b from both sides )
3b - 24 = 0 ( add 24 to both sides )
3b = 24 ( divide both sides by 3 )
b = 8
Then
∠ EBF = 2x = 2(8) = 16°
