Answer: 3
Explanation:
It is useful to summarise the information in the form of a table with columns for distance, speed and time.
Remember if you know two of these, you can write an expression or answer for the third one.
s = d/t and t = d/s and d = s × t
We have that the speed on Monday was x miles per hour and the time, 1/2 an hour. We can find the distance as x × 1/2
Show this on the table and then complete it for Tuesday as well.
Distance Speed Time
−−−−−−−−−−−−−−−−−−−−−−−−
Monday 1/2 x x 1/2
Tuesday 1/2 x (x-2) 3/4
The speed on Tuesday can be given in two ways:
It is the same as on Monday (1/2 x) or as s × t
Form an equation: 3/4 (x-2) = 1/2 x
4 x 3/4 (x-2) = 4 x 1/2 x ← x 4
3 (x-2) = 2x
3x - 6 = 2x
x = 6 ← this was the speed on Monday.
The distance run on Monday was 1/2 x 6 = 3 miles
That's all the square roots of the form 5.xxxx. The numbers start at 5² and end at 6²-1.
So that's 6² - 5² = 11 numbers. We can list them:
25,26,27,28,29,30,31,32,33,34,35
Answer: 11
Answer:
Negative number
Step-by-step explanation:
For example, |-5| = 55. This is because -5 is considered to be 5 units away from 0.
