1 = x + x
1 = 2x
1/2 = 2x/2
x = 1/2 or 0.5
e) 5 = 4x
=> 5/4 = 4x/4
=> x = 5/4 or 0.8
c) 6x = x - 15
=> x - 15 = 6x
=> -15 = 6x - x
=> -15 = 5x

Answer:
x=30
Step-by-step explanation:
you would call those alternate exterior angles meaning that they are the same angle, so all you have to do is reverse the equation meaning you do 75-15=60 and you would then divide by 2 to get X so 60/2=30, so x=30
Answer:
x = 30
Step-by-step explanation:
2x+15 should be vertical to angle 5
75 is vertical to angle 4.
If we were to look at angles 4 and 5 those are alternate interior which means they have to be congruent.
2x+15=75
2x=75-15
2x=60
x=30

Answer:
Math class ends at 10:35 AM.
Step-by-step explanation:
To find the answer, you need to add 40 minutes to the timestamp if 9:55 AM. There are 60 minutes in an hour, so you add five minutes to get to 10:00. 40-5=35. Now add 35 minutes to 10:00. The answer is 10:35 AM.
Answer:
The answer is 10:35 AM.
Step-by-step explanation:
Given;Mr Gleasons math class lasts for 40 minutes.Math class starts at 9:55 AM.To Find;At what time does math class end.Here, we know that in one hour there's 60 minutes.
1 hour = 60 minutes.

Teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on. Both sets of data have a mean teaching year of 8. 2, with data recorded from 200 teachers at High School A and 221 teachers at High School B. On the histograms, each interval represents possible integer values from the left endpoint up to but not including the right endpoint. (a) The median teaching year for one high school is 6, and the median teaching year for the other high school is 7. Identify which high school has each median and justify your answer. (b) An additional 18 teachers were not included with the data recorded from the 200 teachers at High School A. The mean teaching year of the 18 teachers is 2. 5. What is the mean teaching year for all 218 teachers at High School A
The mean teaching year for all 218 teachers at High School A is 7.73 if the teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on.
What is a histogram?It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.
We have two histograms representing the teaching year with frequency.
From the first histogram the two reactangles represents = 45+48 = 93
From the second hisogram = 79+34 = 113
Median divided into two equal parts.
From the data:
The first graph has 200 points
The second graph has 221 points
The first graph median should be near the 100th data point
The second graph median should be the 111th data point
We obtain 93 from rectangles on a, which is less than 100, and these two rectangles include 1-4 and 4-7 (not including?) As a result, we might argue that this data covers 1-6.
We clearly need more values after we reach the medians, thus we must include the following interval. As a result, in a medium, 7 should be used.
The same reasoning applies to b), where the first two rectangles yield 113 and the median is the 111th datum point. We don't need to add these two rectangles because it includes them. So, for this median, the next interval (7-10) must be 6.
For part (b):
Mean of 18 = 2.5
= 2.5×18 ⇒ 45
Mean of 200 = 8.2
= 200×8.2 ⇒ 1640
New mean = Total/number of observation
= (45+1640)/(200+18)
= 1685/218
= 7.729
= 7.73
Thus, the mean teaching year for all 218 teachers at High School A is 7.73 if the teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on.

Step-by-step explanation:
due to her having triplits it will be a 1/3 chance that they will all be boys because you need to take in account the three children
Answer:
Step-by-step explanation:
There are 8 different ways that the order of the children is 1/8 for each one.
So for boy * boy * boy = 1/2 * 1/2 * 1/2 = 1/8
All of the other possibilities also produce 1/8 because each child has a possibility of 1/2 to be a boy or a girl.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Number of bricks in a row = 23
Number of bricks in column = 130
Total number of bricks = 23 * 130

For moves less than 50 miles, a moving company charges $180 per hour and a $50 gas fee.
Which function rule represents the amount in dollars, C, the company charges for h hours?
A:OC=50h - 180
B:OC=50h+ 180
C:OC=180h+ 50
D:OC= 180h - 50
Answer:
C
Step-by-step explanation:
the 50 miles don't really matter in this situation. 180$ per hour will be 180h (as we don't know the number of hours used) and the 50$ gas fee, which is what C is representing.
Answer:
C: C = 180h + 50
Step-by-step explanation:
180 per hour, with h representing how many hours, and then you need a $50 gas fee. So, the answer would be C = 180h + 50
Solve the equation 4(x + 5) = 9x + 4x − 34, and show your work
Answer:
x = 6
Step-by-step explanation:
: 4(x + 5) = 9x + 4x − 34
Combine Like Terms:
- 4x + 20 = 9x + 4x − 34
- 4x + 20 = 13x − 34
Subtract 20 from both sides:
- 4x + 20-20 = 13x − 34-20
Subtract The numbers:
= 4x = 13x - 54
Subtract 13x from both sides:
= 4x-13x = 13x - 54-13x
Combine Like terms:
- 9x = -54
Divide both sides by the same factor:
-9x / -9 = -54 / -9
Cancel terms that are in both the numerator and denominator:
x = -54/-9
Divide the Numbers:
x = 6

Answer:
x-intercept : (-1.2,0)
y-intercept : (0,-0.7)
Step-by-step explanation:
Hello!
An x-intercept is when the y-value is 0, and a y-intercept is when the x value is 0.
Another way to think about it, x-intercepts intersect with the x-axis, while the y-intercept intersects with the y-axis.
A coordinate, a point on a graph, is written as (x,y) or x-position and y-position.
x-intercept : (-1.2,0)
