Help! given 2(x-9)=-10 prove x=4 with statements and reasons
Step-by-step explanation:
Proof:
2 ( x - 9) = - 10 when x = 4
2 ( 4 - 9) = -10
8 - 18 = -10
-10 = -10 ..........hence proven
Reasons
- When you replace X with 4, you can clearly see that the equation is equal to -10.

The answer you are looking for is
Solution/Explanation:
First, writing out the equation,
3x+5=2x-2x+29.
Next, making the equation more simple by subtracting 2x-2x, which is 0,
3x+5=0+29.
3x+5=29.
Now, subtracting 5 from both sides of the equation,
3x+5-5=29-5.
3x=24.
Finally, dividing both sides of the equation by 3,
3x/3=24/3.
x=8.
So, therefore, the final answer is x=8.

use the substitution method to solve the sstem of equations choose the correct ordered pair 2x-y=10 and 2x-2y=4
Answer:
(8, 6)
Step-by-step explanation:
2x - y = 10
2x - 2y = 4
=>
x - y = 2
x = y + 2
we put that into the first equation
2×(y+2) - y = 10
2y + 4 - y = 10
y + 4 = 10
y = 6
=>
x = y + 2 = 6 + 2 = 8
so, we have a ordered pair (x, y) = (8, 6)
Madison lives between Anoa and Jamie as depicted on the line segment. The distance between Anoa's house and Madison's house is represented by 3x+2 miles, the distance between Madison's house and Jamie's house is represented by 3x+4 miles, and the distance between Anoa's house and Jamies house is represnted by 9x-3 miles. Find the value of x. Then find the distance between Madison's house and Jamie's house.
Answer:
x = 3
13 miles between Madison and Jamie's house.
Step-by-step explanation:
If we add the distance between Anoa's and Madison's house with the distance between Jamie's and Madison's house, then we get the total distance between Anoa's and Jamie's house.
(3x + 2) + (3x + 4) = 9x - 3
Let's add up the terms first
3x + 2 + 3x + 4 = 9x - 3
6x + 6 = 9x - 3
Let's move the variables to the right side by subtract 6x from both sides
6x + 6 = 9x - 3
-6x -6x
6 = 3x - 3
Add 3 to both sides
6 = 3x - 3
+3 +3
9 = 3x
Isolate the variable, x, by dividing both sides by the coefficient, 3.
9/3 = 3x/3
x = 3
Now we need to find the distance between Madison's and Jamie's house.
3x + 4
Plug in 3 in place of the x
3(3) + 4
9 + 4 = 13
Answer:
Step-by-step explanation:
If we add the distance between Anoa's and Madison's house with the distance between Jamie's and Madison's house,then we get the total distance between anoa's and Jamie's house.

Is 5.787787778... a rational or irrational number?
Explain.
Answer:
For a number to be rational, it must:
-terminate (0.5) or repeat (0.3333...)
-be able to be written as a fraction
If a number does not meet this criteria, then it is irrational. Thus, 5.787787778... is irrational.

Answer:

Step-by-step explanation:

A fine jewelry store leased a space at the mall with a base rent of $1,800 a month, plus 4% of all sales over $200,000. If the gross sales were $325,000, what was the total amount of rent paid by Heinz Fine Jewelry at the end of the year?
Answer:
So, first, we have to establish how much the base rent ends up costing. So to find that, we do 1,800x12=21,600. So the base rent is $21,600. Then, we add the 4% of sales which is 125,000x0.04=5,000. So, we add $21,600 with $5,000 and we get a final answer of $26,600 owed at the end of the year :)

B c² = h² + b² -2bx +x²
Step-by-step explanation:
The square of the binomial can be expanded using the distributive property:
c² = h² +(b -x)²
c² = h² +(b -x)(b -x)
c² = h² +b(b -x) -x(b -x)
c² = h² +b² -xb -bx +x²
c² = h² +b² -2bx +x² . . . . . matches choice B

11. The news reports that today's high temperature is 16°F colder than
yesterday's high temperature. Yesterday's high temperature was -2°F.
a. Write an expression to represent today's high temperature.
b. Reasoning is today's high temperature positive or negative? Why?
The expression to represent today's temperature is given by
- 2°F - 16°F = - 18°F and todays high temperature is negative as the
temperature is colder.
Temperature is a numerical expression of how hot a substance or radiation is.
There are three different types of temperature scales: those that are defined by the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron, in a body, like the SI scale. Those that rely only on macroscopic properties and thermodynamic principles, like Kelvin's original definition of temperature. Those that are not defined by theoretical principles but rather by useful empirical properties of particulate matter.The temperature yesterday was -2°F . The temperature is colder today and by 16°F more cold.
Since colder temperature is denoted by negative sign and hotter temperature by the positive sign then when the temperature is colder today then we have to subtract the values to the given values.
Hence - 2°F - 16°F = - 18°F .
So todays high temperature will be a negative value.

Anton joined a golf club. He pays an annual membership fee of $895 and greens fee of $30 each time he plays golf. Last year he paid $2,065 as a total golfing fee. How many games did he play? Write and solve the equation.
Answer: f(g) = 895 + 30g
-----------------------------------------------------------------
He paid $2065. Number of games he played:
-----------------------------------------------------------------
2065 = 895 + 30g
30g = 2065 - 895
30g = 1170
g = 39
-----------------------------------------------------------------
Answer: He played 39 games.
Step-by-step explanation:
Number of games anton played is 39; the equation is 2065 = 895 + 30G
How to find the system of equations needed to solve an equation?An equation usually consists of equality of two mathematical expressions. Let it be
A = B
. If we take them to be equal to third variable, then:
A = B = C
type of equation is obtained.
We can then take it as system of two equations as:
A = C\\ B=C
Solution to this system will give us the solution to the considered equation.
Solution to an equation is finding values of the variable included in the considered equation for which the equation considered evaluates to be true.
The equation will be f(g) = 895 + 30G
Amount anton paid = $2065.
Number of games he played;
2065 = 895 + 30G
30g = 2065 - 895
30g = 1170
G = 39.
Therefore, the solution of the equation os 39
