How many solutions for 3(2x+5)-6x=40
The given linear equation can be simplified to:
15 = 40
Which means that the equation has no solutions.
How many solutions we have for the given equation?
Here we have the linear equation:
3*(2x + 5) - 6x = 40
And we want to see how many solutions does this equation has.
The solutions are the values of x such that the equation becomes true.
Then we can rewrite:
3*(2x + 5) - 6x = 40
Distributing the product we get:
3*2x + 3*5 -6x = 40
6x + 15 - 6x = 40
(6x - 6x) + 15 = 40
15 = 40
Notice that this equation does not depend of x, and it is false, (15 is not equal to 40)
So there are no value of x such that the equation is true, which means that the linear equation has no solutions.

Answer:
1. x = 4, y = 1
Graph: (See the attachment)
Step-by-step explanation:
x + 2y = 6
x - y = 3
x + 2y = 6
x = -2y + 6
x - y = 3
-2y + 6 - y = 3
-3y + 6 = 3
-3y = -3
y = 1
x = -2y + 6
x = -2 ( 1 ) + 6

Madeline sold 200 tickets for a charter flight to Dallas. Some paid $200 for their tickets and some paid
$250. Madeline's revenue for the flight was $44,000. Below is Madeline's work in determining how
many of each ticket was sold.
x = number of $200 tickets
y = number of $250 tickets
200 (200 - 1) + 250y = 44,000
40.000 - + 250y = 44.000
40.000 + 249 y = 44.000

There are two similar triangles in the diagram. Find the unknown measurement.
Answer: x=180
Step-by-step explanation:
360/120=x/60
3=x/60
x=180
By the similarity of triangles the length of the side RS is 180 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know in similar triangles the ratio of their corresponding sides are equal.
Given, Are two triangles OPQ and ORS.
Therefore,
OP/PR = PQ/RS.
120/360 = 60/x.
120x = 21600.
12x = 2160.
x = 2160/12.
x = 180.

Submit what’s r
After the solution of the two-step equation, we can conclude that R = 5.
What do we mean by two-step equations?A two-step equation is one that must be solved in two steps. First, we must eliminate any constants that are on the same side as the variable. To solve, isolate the variable by itself using inverse operations. Remember that whatever you do to one side must be done to the other.So,
Given: R/4 - 9.8 = 10.2Then,
R/4 - 9.8 = 10.2R/4 - 9.8 + 9.8 = 10.2 + 9.8R/4 = 20R = 20/4R = 5Therefore, the value of R is 5.

The graph shows the amount of money in Amy's bank account and her spending activity. Does the graph show a proportional relationship?
A. Yes, it is proportional because it has a constant rate of change.
B. No, it is not proportional because it has a constant rate of change.
C. Yes, it is proportional because it has a y-intercept.
D. No, it is not proportional because it has a y-intercept that is not zero.
Answer:
Option A:
Yes, it is proportional because it has a constant rate of change.
Step-by-step explanation:
One trick you can use to easily tell a proportional graph is that it follows a straight line. It does not matter whether the line slopes downwards or upwards. The fact that it is straight and not cured at any point, should hint you that the graph is proportional.
Proportional graphs have a constant rate of change. The value of the slope calculated when using any two (x, y) coordinates are the same for any point along the line.

in the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?
Answer:
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.Step-by-step explanation:
good morningIf the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
For which the parameters are given as follows:
m is the slope, representing the rate of change of the function.
b is the intercept, representing the value of y when x = 0.
When two lines are parallel, they have the same slope.
Hence, If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

The three main types of geography are physical, environmental and human geography. There are other sub-branches of geography such as political geography, historical geography and religious geography.
Physical geography deals with the study of Earth and its structure. The landforms, continents, oceans and tectonic movements are a part of physical geography. The formation of rocks, weathering, forces of erosion, winds, ocean currents and rivers are all studied as a part of physical geography. Environment geography deals specifically with the study of the interaction of plants and animals with Earth. Human geography focuses on how human societies flourish with the help of natural resources. It deals with the study of the evolution of cultures and religious beliefs. Economic, cultural and political geography are sub-branches of human geography.

can anyone solve 84=4(1 - 4g) step by step?
Answer:
g= -5
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
84-(4*(1-4*g))=0
84 - 4 • (1 - 4g) = 0
3.1 Pull out like factors :
16g + 80 = 16 • (g + 5)
16 • (g + 5) = 0
4.1 Solve : 16 = 0
This equation has no solution.
A a non-zero constant never equals zero.
4.2 Solve : g+5 = 0
Subtract 5 from both sides of the equation :
g = -5

Step-by-step explanation:
Step 1: Define equation
84 = 4(1 - 4g)
Step 2: Solve for g
Distribute 4: 84 = 4 - 16gIsolate g term: 80 = -16gIsolate g: -5 = gRewrite: g = -5Step 3: Check
Plug in g into the original equation to verify it's a solution.
Substitute in g: 84 = 4(1 - 4(-5))Multiply: 84 = 4(1 + 20)Add: 84 = 4(21)Multiply: 84 = 84Here we see that 84 does indeed equal 84.
∴ g = -5 is a solution of the equation.
