For this case we have the following inequality:

From here, we define the variable x.
x: number of minutes remaining to finish the race.
From here, we clear the value of x.
We have then:

Therefore, Samuel has less than 22.5 minutes to finish the race in the estimated time.
Answer:
x < 22.5; Sam has fewer than 22.5 minutes left to finish running.
Answer:
13/15 > 4/5 is a true stament.
Step-by-step explanation:
The left side is 0.86 repeating turned into a decimal. which means 0.86 is greater than the right which the right is 0.8 turned into a decimal. which in this case this means that the given stament is always true.
36/60 = 18 / 30 = 9 / 15 = 3/5 , so 36 is 60% of 60, or 40% less than 60. This question is worded oddly, is that what you're looking for?
Here, GCF of 18 & 32 is 2, so take it as common factor,
18b - 32 = 2(9b - 16)
In short, Your Answer would be: 2(9b - 16)
Hope this helps!
Answer:
1 7/18
Step-by-step explanation:
5/9 + 5/6 write all numerators above the least common denominator which is 18.
10+15/18 then you add the numerators which will make it 25/18 which alternative form will be 1 7/18, or in decimal 1.38
