Answer: 16,17,18
Step-by-step explanation:
(x)+(x+1)+(x+2) = 51
x+x+x+1+2=51
3x+3=51
3x=51-3
3x=48
x=16
x+1 = 17
x+2= 18
Step-by-step explanation:
1. The first is a tabulation of the data, in an organized, clear and concise way for each event.
2. After tabulation, for a better understanding of the data, statistical data, such as the mean, median, and standard deviation of each event, should be collected.
3. Finally, graph the data obtained to see the trend of both cases and thus have a very precise way to make the comparison of both events
Answer:
Perpendicular bisector theorem
Step-by-step explanation:
The illustration of the theorem is:
If point B is a perpendicular bisector of Line AC and the length of AC is 10cm
Then
Where
--- Perpendicular bisector
So, the equation becomes
Recall:
Answer:
2n=5
(n=2.5)+14
Step-by-step explanation:
<span>Josh swims 5 more hours per week than David so his hours = 3x + 5
His </span><span>average speed is 4 laps per hour less than David's so it is = x - 4
</span>
Total distance = hours * speed
= (3x + 5)*(x - 4)
= 3x^2 - 7x - 20
Ans is C
