Answer:
The absolute change is 10,414
Step-by-step explanation:
To get the absolute change, we simply use the mathematical formula below
Absolute change = New value - Original value
From the question, the new value is 18,108 while the original value is 28,522
So the absolute change will be;
28,522-18,108 = 10,414

Solve for x 2.3x-3.2+1.6x=.7x
Answer:
x=1
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2.3x −3.2 + 1.6x = 0.7x
2.3x + − 3.2 + 1.6x = 0.7x
(2.3x + 1.6x) + (−3.2 )= 0.7x (Combine Like Terms)
3.9x + −3.2 = 0.7x
3.9x − 3.2 = 0.7x
Step 2: Subtract 0.7x from both sides.
3.9x − 3.2 − 0.7x = 0.7x − 0.7x
3.2x − 3.2 = 0
Step 3: Add 3.2 to both sides.
3.2x − 3.2 + 3.2 = 0 + 3.2
3.2x = 3.2
Step 4: Divide both sides by 3.2.
x = 1

8 (x -3) +7 = 2x (4 -17)
8(x -3) +7 = 2x (-13) here was the error because the had 13 that is incorrect
8x -24 +7 = -26x
8x -17 = -26x
-17 = -26x -8x
-17 = -34x
-17/-34 = x
1/2 =x

A rectangular computer monitor is measured by the length and width of its display resolution. Three different monitors are described below. Monitor A has a display resolution of 640 pixels by 480 pixels. Monitor B has a display resolution of 800 pixels by 600 pixels. Monitor C has a display resolution of 1,280 pixels by 800 pixels. Which of the monitors are similar, based on their display resolution
Answer: Monitors A and B
Step-by-step explanation:
The similar monitors based on display resolution are those with similar ratios.
Take the ratios to their simplest forms to see which are similar.
Monitor A
= 640 : 480
= 16 : 12
= 4 : 3
Monitor B
= 800 : 600
= 8 : 6
= 4 : 3
Monitor C
= 1,280 : 800
= 32 : 20
= 8 : 5
Monitors A and B are similar as they have the same display ratio.

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..
Given:
The point is (-2,4).
To find:
Whether the point (-2,4) satisfy [tex]y<3x+5,y=3x+5[/tex] or [tex]y >3x+5[/tex].
Solution:
We have a point (-2,4).
Substituting x=-2 in 3x+5 and check whether it is greater, equal or less than y value, i.e., 4.
[tex]3x+5=3(-2)+5[/tex]
[tex]=-6+5[/tex]
[tex]=-1[/tex]
-1 is less than 4.
[tex]3x+5<4[/tex]
[tex]3x+5<y[/tex]
In can be written as
[tex]y>3x+5[/tex]
Therefore, the given point (-2,4) satisfy [tex]y >3x+5[/tex].

The numerator of a rational number 8
Answer:
We conclude that the numerator of a rational number 8 will be 8.
Step-by-step explanation:
We know that any number which can be written in the form p/q is called a rational number.
i.e. p/q
Where p and q are integers and q≠0.
Here:
The numerator is pThe denominator is qGiven the number
8
As number '8' can be written in the form p/q, so it is a rational number.
i.e. 8/1
Thus,
The numerator = 8The denominator = 1Therefore, we conclude that the numerator of a rational number 8 will be 8.
solve for x- 5(x+4)=30
Answer: x= -12.5
Step-by-step explanation:
Start with distributing-5(x+4) or you get
x-5x-20=30
Add x and -5x to get -4x
Thank you add 20 to each side and get
-4x = 50
Divide by -4 on each side to get x=-12.5
Answer:
x=-25/2 is the answer.
Step-by-step explanation:
Below are the steps for solving the equation:
Step 1: Simplify, combine like terms, and distribute:
x−5(x+4)=30
x+(−5)(x)+(−5)(4)=30
x+−5x+−20=30
(x+−5x)+(−20)=30
−4x+−20=30
−4x−20=30
Add 20 to each side:
−4x−20+20=30+20
−4x=50
Divide each side by -4:
-4x/-4=50/-4
x=-25/2, which is -12.5 as a decimal.
So, your answer is x=-25/2 as a fraction, which is also -12.5 as a decimal.
Consider the triangle. Which statement is true about the length of the sides?
Each side has a different length.
Two sides have the same length, which is less than the length of the third side.
The three sides have the same length.
The sum of the lengths of two sides is equal to the length of the third side.
Answer:For this case we observe that the 2 angles of the triangle are equal. Also, we have by definition:
A triangle is , when the three sides are connected(in addition, the three internal angles measure 2 angles 45 degrees and 1 angle 90

Answer:
1/2
Step-by-step explanation:
remember that the formula for the slope of a line is
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:
Point 1 : (-1,3) and Point 2 : (1,4)
Plug in your values:
[tex]m=\frac{4-3}{1-(-1)}[/tex]
[tex]m=\frac{1}{2} \\[/tex]
So the slope of this line is 1/2 !
Answer: The slope is [tex]\frac{1}{2}[/tex].

Answer:
Adrian lives closer to the school by A. 1,250 meters.
Step-by-step explanation:
1 kilometer = 1,000 meters
So, if Kevin's home is 2 kilometers from the school, then it is also 2,000 meters away, since 1,000 x 2 = 2,000.
Adrian lives 750 meters, or 0.75 kilometers away from school.
2,000 - 750 = 1,250.
Therefore, Adrian lives closer to the school by A. 1,250 meters.
Hope this helps! :D
