A tributary joins a river at an angle. Find the value of x.
WhAt this is- just- uGh
Answers
Answer:
x = 53
Step-by-step explanation:
I'm going to assume that this is just a real-life scenario of two lines intersecting to create two adjacent angles that are also a linear pair. So, the following equation can be set up to solve for x.
x + 2x + 21 = 180
3x + 21 = 180
3x = 159
x = 53
Time to check.
53 + 2(53) + 21 = 180
53 + 106 + 21 = 180 It works!
Answer:
x = 53º
Step-by-step explanation:
The two angles form a supplementary angle, telling us that the sum of the two equal 180º, allowing us to form one side of the equation.
2x + 21 + x = 180
+x
3x + 21 = 180
-21 -21
3x = 159
159/3 = 53
x = 53º
(also I know it doesn't say you have to find the value of each angle but just in case lol)
Now that we have x, the first angle equals 53º. Just plug in 53 to the other side
2(53) + 21
106 + 21 = 127
just to check, 127 + 53 = 180

JJ’s Fitness Club offers two different fees for their yoga classes. Club members are charged a one-time membership fee of $24 and pay $3 per class. Non-members pay $7 per class. How many classes result in the same cost for a member and non-member?
Answers
Answer:
So the answer is 13 classes member and 9 non member
Step-by-step explanation:
so you gotta do 24 + 3x = 7y ok?
and x equals 13 so 39 + 24 = 63
and non member is 7x = 63
x = 9
Hope I helped :D
Members Nonmembers
Cost in Dollars 10+3x 0+5x
Step Two: We create an equation to solve for x.
Member Cost=Nonmember Cost
10+3x= 0+5x
Step Three: Solve for x:
10+3x= 5x Subtract 3 from both sides
10=5x-3x Combine like terms
10=2x
5=x

A survey of a group of seventh-graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.
Students
A dot plot titled Students. A number line going from 0 to 9 labeled the number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.
Teachers
A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.
Based on the shape of the two-dot plots, which statements correctly compare them? Select three choices.
The center of the data for students has a value less than that of the center of the data for teachers.
The center of the data is to the right of the dot plot for both teachers and students.

the start of the question gives x=-2 which then you flip the signs to get -x=2. The point that corresponds with 2 is F
b) |-1.5|= E
When a negative number is put in absolute values it becomes positive so in this case we would be looking for the point which had a value of 1.5 which is point E
c) -4= C
-4 is corresponding to C
d) |5|= H
As 5 is already positive the absolute values don’t matter. H corresponds with the number 5
e) |-6|=I
Similar to (b) the number is negative so the absolute values would make it positive and positive 6 is located at I

Answer:

Step-by-step explanation:
In a square all the sides are the same. Since a triangle is half of a square, we find the area of a square then divide it by 2. So if one side is 16, we multiply 16x16 and get 256. 256/2=128

Least to Most Likely:
In this order:
Honor (1/10=10%)
Simple (30%)
Bonus (3/5=60%)
Answer: honor tile, then simple tile, then bonus tile.
Explanation:
Let's get all the probabilities to become a fraction with a denominator of 10 so it will be easier to compare
simple tile - 30% equals 0.3=3/10
honor tile - 1/10 is already good
bonus tile - 3/5=6/10
1/10 is the least likely, followed by 3/10, and 6/10 is the most likely
honor tile, then simple tile, then bonus tile.
