[tex]2x - 11 = k[/tex]
Add sides 11
[tex]2x - 11 + 11 = k + 11[/tex]
Simplification
[tex]2x = k + 11[/tex]
Divide sides by 2
[tex] \frac{2}{2} x = \frac{k + 11}{2} \\ [/tex]
[tex]x = \frac{k + 11}{2} \\ [/tex]

Maya estimates that the wait time for her favorite roller coaster is 35 minutes. The actual wait time is 55 minutes. What is the percent error of laya's estimate
Answers
Answer:
36.4%
Step-by-step explanation:
Actual wait time is 55 minutes
Approximate wait time is 35 minutes
Therefore the percent error can be calculated as follows
= 35-55/55 × 100
= 20/55 × 100
= 0.3636 × 100
= 36.4%

The water level in a reservoir is now 52 meters. If this was a 23% increase, what was the initial depth?
Answers
Answer:
40.04
Step-by-step explanation:
It was at 40.04 before the 23% increase. To find 23 % of 52 set it up as a inequality.
x/52 = 23/100
Cross multiply
52 * 23 = 1,196 100 * x =100x
Now solve for x.
100x /100 = 1,196/100 x = 11.96
Subtract answer from 52 to get answer
52 - 11.96 = 40.04

Your answer is 50 (or b)
Step-by-step explanation:
You can tell this because the inside angle is 25 but the cornner says 2x so you have to double it so 25+25=50...hope this helps
:P
Answer:
50
Step-by-step explanation:
There is a straight line at the bottom which is 180 degrees. On the right side the angle measure is 150 degrees so you subtract that by 180 and you get 30 degrees making it supplementary. Next you should know that there is 180 degrees in a triangle. Now you formulate the equation 30+50+2x =180. Then you solve for x and you get the solution x=50 which is your answer. Now you can substitute 50 in for x and see if all the angle measures add up to 180 degrees.

The point (-4, 1) is rotated 180 degrees counterclockwise using center (-3, 0). What are the coordinates of the image?
Answers
Answer: Coordinates of the image are (-2 , -1)
Step-by-step explanation:
The rule for 180° rotation counterclockwise is:
(x , y) ⇒ (-x , -y)
This means that to get the coordinates of a point rotated 180° counterclockwise, all you have to do is flip the signs of both the x and the y
Now, we are given the point (-4 , 1)
Applying the above rule:
[tex]( x image, y image) = (-(-4),-(1))[/tex]
[tex](x image, y image) =(-2, -1)[/tex]

A triangle has angle of 30 degree, 60 degree, 90 degree. It is dilated by a scale of 3. Give the angle measures of the dilation of the triangle.
Please help me with this question and explain your answer too...
Answers
Answer:
No matter what scale factor is dilated, the angles will not change.
My explanation:
A 30-60-90 right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The triangle is significant because the sides exist in an easy-to-remember ratio: 1:√3:2.
That is to say, the hypotenuse is twice as long as the shorter leg, and the longer leg is the square root of 3 times the shorter leg. You might also remember it as "X, 2X, and X roots of 3", which is how I remember it, but then you have to remember that 2X is actually the longest side, not X roots of 3.
Which side is which? The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3
times as long, and the side opposite the 90 degree angle will be twice as long. The triangle below diagrams this relationship. Remember that the longest side will be opposite the largest angle, and the shortest opposite the smallest angle.
Hopefully this helped, if not HMU and I will try to get you a better answer! :)

Lisa and Molly are on a bridge and see a tree sticking out of the water. Use the diagram to determine how far away Lisa is from the tree in the water. Use appropriate units.
Answers
Answer:
Distance between Lisa and the tree in the water = 26.5 ft
Step-by-step explanation:
From the figure attached,
Lisa is a point L, Molly is at M and a tree stick at point S.
By applying sine rule in ΔLMS,
[tex]\frac{\text{SinL}}{\text{SM}}=\frac{\text{SinM}}{LS}=\frac{\text{SinS}}{\text{LM}}[/tex]
[tex]\frac{\text{Sin(54)}}{22}=\frac{\text{Sin(103)}}{\text{LS}}[/tex]
LS = [tex]\frac{22\times \text{Sin}(103)}{\text{Sin(54)}}[/tex]
LS = 26.5 ft
Therefore, distance between Lisa and the tree in the water is 26.5 ft.
