x = 4
Hope this helps
plz mark as brainliest!!!!!!!
Step-by-step explanation:
Hey there!
Variables have the unknown value.
If you want to find or know value from the equation easily, you have to simply solve the equation.
For your example;
2x+3=11
Now, solve it to get value of variable 'x'.
2x = 11-3
2x = 8
[tex]x = \frac{8}{2} [/tex]
Therefore the value of variable 'x' is 4.

Layla measured a line to be 6.8 inches long. If the actual length of the line is 6.5 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answers
Given parameters:
Measured length = 6.8inches
Actual length = 6.5 inches
Unknown parameter is the percentage error
Errors introduce uncertainty into a reading. Often times measurement errors are incurred in a process due to diverse reasons. This error can be due to the problems with the measuring device, incorrect reporting of measured values and also, the scientist can be at fault.
Deviation from the actual measurement leads to the concept of accuracy.
To solve this problem, we need to find the absolute error;
Absolute error = | Measured length - Actual length|
Input the variables given and solve;
Absolute error = | 6.8 - 6.5| = 0.3 inches
Now, let us find the percentage error;
Percentage error = [tex]\frac{Absolute error}{Actual length} x 100[/tex]
Input the parameters and solve;
Percentage error = [tex]\frac{0.3}{6.5} x 100[/tex] = 4.615%
To the nearest tenth percent = 4.6%
Therefore, the percentage error to the nearest tenth percent = 4.6%

Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
The coordinates of point B of the line segment are (-3, -7).
What is the midpoint of a line segment?A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.
The formula to find the midpoint of line segment is (x, y) = [(x₁+x₂)/2, (y₁+y₂)/2]
Given that, the midpoint of AB is M (-1, -2).
The coordinates of A are (1,3).
Let the coordinates of point B are (x, y)
Here, (-1, -2) = [(1+x)/2, (3+y)/2)
-1=(1+x)/2 and -2=(3+y)/2
-2=1+x and -4=3+y
-3=x and -7=y
The coordinates of point B are (-3, -7)
Therefore, the coordinates of point B of the line segment are (-3, -7).

Jacob attempted the third problem above but when checking his work realized he made a mistake. Identify what Jacob’s mistake was in your own words, and explain what Jacob would need to do differently to avoid making that mistake in the future:
Answers
Answer:
When solving, Jacob did not distribute properly.
Explanation:
Let's talk about 5(x + 2). The correct distribution would be 5x + 10. Jacob distributed 5 into x correctly and got 5x, however he did not distribute the 5 into 2 properly. It should have been 10, however it stayed as 2.
Jacob should be more careful when distributing, and make sure to distribute into EVERY term inside the parentheses.

For this problem, it's important to understand what an angle bisector is. An angle bisector is simply a line that splits an angle into two equal portions. In this problem, <ATS is bisected by TR which gives us <ATR = <RTS = 1/2 <ATS.
Let's use this information to solve our equation to find x.
m<RTS = 1/2 m<ATS
17x - 5 = (1/2) (28x + 8)
17x - 5 = (1/2)(28x) + (1/2)(8)
17x - 5 = 14x + 4
17x - 14x - 5 = 14x - 14x + 4
3x - 5 = 4
3x - 5 + 5 = 4 + 5
3x = 9
3x * 1/3 = 9 * 1/3
x = 3
Hence, we have found the value of x to be 3.
