A cell phone company charges $45 per month for unlimited calls and $0.25 per text messages. Another call phone company $0.15 per text messegaes and $70 per month for unlimited calls. Write an equation to reoresent when the cost from both compsnies will be the same after one month
Answers
Answer:
You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

Tom received an allowance of $300 for his upcoming trip to Canada. He knows that he will spend $15 each day on food. Which equation represents the amount of extra spending money, m, that Tom will have after d days on his trip?
Answers
Answer:
m=15d-300
Step-by-step explanation:
Answer:
300-15d = m
Step-by-step explanation:
Since he spends 15 each day, we dont know how many days, so we put 15d to represent $15 spent each day (d)
We use this formula above ^ and subtract that from 300, which is why it's
300 - 15d
Lastly, we need to find money remaining, so 300 - 15d = m

What is substitution method?The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.
Given, equations
2x + y = 7 -------(a)
3x -2y = -7 -------(b)
Taking equation (a)
2x + y =7
y = 7 - 2x ------(c)
Substituting value of y in equation (b) from equation (c)
3x - 2(7 - 2x) = -7
3x - 14 + 4x = -7
7x = 7
x = 1
Putting value of x in equation (c)
y = 7 - 2 (1)
y = 5
Hence, x = 1 and y = 5 is the solution for the given equations 2x + y = 7 and 3x -2y = -7.

What are the properties of equality?Facts regarding any two or more quantities connected by the equal sign are known as properties of equality.
There are four types of properties of equality.
Addition property, when two equal quantities are increased by a common value, the equality is preserved.
Transitive property of equality, entities that are equivalent to one another are also equivalent to one another.
Subtraction property, equality is maintained when a common term is subtracted from two equal terms.
Multiplying by a common term do not alter the equality, according to the multiplication property of equality.
Given, An equation 3x + 2 - x = 11x + 9.
The first step would be subraction property of equality.
We'll subtract 2 from each side of the equation.

Answers
Answer:
Disagree with Lin: There are no solutions because 12x+2x is equal to 14x, if 14x=14x on both sides, the x variable can be cancelled out since they have the same slope
Step-by-step explanation:
I agree with Lin the system of equation 2x - 32 + 4(3x - 2462) = 14x

What are the three types of solutions for a system of linear equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Given, An equation 2x - 32 + 4(3x - 2462) = 14x.
2x - 32 + 12x - 9848 = 14x.
14x - 9880 = 14x.
So, 14x - 9880 ≠ 14x and has no solution.

Answers
Answer: D. X = 6 maps to y = 2
Step-by-step explanation:
i guessed and got it right lol
The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
Option D is the answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
A function can have the same output for different inputs.
A function can not have different outputs for the same inputs
Now,
y = 4 when x = 6.
Other possible mappings are:
A.
x = 4 maps to y = 6
This mapping is possible.
B.
x = 3 maps to y = 2
This mapping is possible.
C.
x = 0 maps to y = 0
This mapping is possible.
D.
x = 6 maps to y = 2
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
E.
x = 1 maps to y = 6
This mapping is possible since we can have different inputs for the same outputs.
Thus,
The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)

Answers

set the equations equal to find when the costs are the same
5.50x+22=7.20x+18

0.25(x + 4) – 3 = 28
Answers
Answer:
x = 120
Step-by-step explanation:
Given
0.25(x + 4) - 3 = 28 ( add 3 to both sides )
0.25(x + 4) = 31 ( divide both sides by 0.25 )
x + 4 = 124 ( subtract 4 from both sides )
x = 120
The value of x that satisfies the equation 0.25(x + 4) - 3 = 28 is x = 120.
Here, we have,
To solve the equation 0.25(x + 4) - 3 = 28, we will follow these steps:
Let's go through each step in detail:
Step 1: Distribute the 0.25 to the terms inside the parentheses.
0.25(x + 4) - 3 = 28
Distribute 0.25 to (x + 4):
0.25x + 0.25 * 4 - 3 = 28
Step 2: Simplify the equation by combining like terms.
0.25x + 1 - 3 = 28
Simplify 0.25 * 4:
0.25x + 1 - 3 = 28
0.25x - 2 = 28
Step 3: Isolate the variable x on one side of the equation.
To isolate the variable x, we want to get rid of the constant term -2 on the left side.
We can do this by adding 2 to both sides:
0.25x - 2 + 2 = 28 + 2
Simplifying:
0.25x = 30
Step 4: Solve for x.
To find the value of x, divide both sides by 0.25:
0.25x / 0.25 = 30 / 0.25
Simplifying:
x = 120
So, the value of x that satisfies the equation 0.25(x + 4) - 3 = 28 is x = 120.

Problem 1
We're given that QE = RW and QW = RE. This is given both in terms of symbols, and also visually in terms of the tickmarks. We have two pairs of congruent sides.
The third pair of sides is the overlapping shared segment of segment WE. So WE = WE by the reflexive property.
From here we use the SSS congruence property to conclude the proof that triangle QWE = triangle REW
==============================================
Problem 2
Segments BC and AE bisect each other. The term "bisect" means "to cut in half".
BC bisecting AE means AD = DE
AE bisecting BC means BD = DC
So we have two pairs of congruent sides. So far, we're on a similar path compared to problem 1. This time however, we'll use a pair of congruent angles instead of the third pair of sides.
Specifically we'll use the fact that
angle ADB = angle CDE
by the vertical angle theorem
Once we know that, we then use the SAS congruence theorem to prove triangle ABD = triangle ECD
To be honest, I'm not sure what you meant by "median", but we don't use any triangle medians here (none of the triangles shown have any medians drawn). You might be thinking of a previous problem.

answer) *
Answers
Answer:

Step-by-step explanation:
If the scale of the drawing is 1:30, it means that the vehicle drawing is 30 times smaller than the actual vehicle.
Vehicle Length / 30 = Drawing LengthWith the above information in mind, we can calculate the length of the vehicle in inches:
Vehicle Length / 30 = 9.95 inVehicle Length = 30 * 9.95 inVehicle Length = 298.5 inFinally we convert inches to feet(dividing inches by 12):
298.5 / 12 = 24.875 feet
