Answers
Answer:

Step-by-step explanation:
36-14 = 22
22/2= 11
11+14 = 25
Answer:
11 and 25
Step-by-step explanation:
The two numbers we'll call x and y. Let's set up equations to model the situation:
x+y=38
x-y=14
Solving the second one for x,
x=y+14
Plug this into the first equation for x and get:
(y+14)+y=36
2y+14=36
2y=36-14
2y=22
y=11
x-y=14
x-11=14

Solution:
Answers
Answer:
y=2/3
Step-by-step explanation:
Answer:
(-2,3) x= -2 y=3
Step-by-step explanation:
The first thing you should do is convert both into standard y=mx+b form
For the first equation you subtract 5y and add 11 to both sides to get
13x+11= -5y
you divide by negative 5 to get
-13x/5-11/5=y
For the second equation we subtract 11y and 7 from both sides to get
13x-7= -11y
divide both sides by -11 to get
-13x/11 + 7/11
We then set both equations equal to each other and solve for x
-13x/5-11/5= -13x/11 + 7/11
Add 11/5 to both sides to get
-13x/5 = -13x/11 + 156/55
Add 13x/11 to both sides to get
-78/55x=156/55
Divide and solve for x to get -2
Then plug x = -2 into the original equations to find y
13*-2 + 5y = -11
-26 + 5y = -11
Add 26 to both sides
5y= 15
y =3

63 40 51 70 36 21 51 28 19 find the mean of data
Answers
Answer:
42.11
Step-by-step explanation:
Add all of the numbers, and then divide the total of the numbers by 9. With 9 being how many numbers are added.
The mean of the given data set is approximately 42.11.
To find the mean of a set of data, you need to sum up all the values and then divide the sum by the total number of values.
Given the data: 63, 40, 51, 70, 36, 21, 51, 28, 19
Here, there are 9 values.
Add up all the values:
63 + 40 + 51 + 70 + 36 + 21 + 51 + 28 + 19 = 379
Divide the sum by the total number of values:
379 / 9 = 42.11
Therefore, the mean of the given data set is approximately 42.11.

A right angle intersects a line at point M. A right angle intersects a vertical line at point M and forms 3 angles. From top to bottom going clockwise, the angles are 1, 90 degrees, 2. Which statement is true about angles 1 and 2? They are congruent. They are right angles. They are complementary. They are supplementary.
Answers
I've attached an image showing the intersection and the angle.
Answer:
C: They are complementary
Step-by-step explanation:
We can see from the image that angle 1, angle 2 and 90° are on a straight line. We know that sum of angles on a straight line is 180°. Thus;
∠1 + ∠2 + 90° = 180°
Rearranging, we have;
∠1 + ∠2 = 180° - 90°
Thus;
∠1 + ∠2 = 90°
Now, from angle proofs in trigonometry, it states that If the non-common sides of two adjacent angles add up to 90°, then it means that the angles are complementary.
In our problem here, sum of ∠1 and ∠2 equals 90°. Also, they are the non-common sides of 2 adjacent angles. Thus, we can say that they are complementary.
