In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.
Answer:
0.72 is the same as 72100 (try putting both into a calculator!) as you can view 1.00 as 11 . Reducing the fraction gives you 72100 = 1825 .
Given
5(x + 27) ≥ 6(x + 26)
Find
The solution set of x
Solution
Eliminate parenthses.
... 5x + 135 ≥ 6x + 156
Subtract 5x+156
... -21 ≥ x
The solution set is all real numbers less than or equal to -21.
Answer:
The correct answer is 6
Step-by-step explanation:
x/10=3/5
then cross multiply
it will now give
5x=30
x=6
