Answer:
y = 9x
Step-by-step explanation:
If you like, you can start with the proportion ...
x/y = 0.1/0.9
Multiplying by 9y gives ...
9x = y
The equation you want is ...
y = 9x
Answer:
15P3 = 15!/ (15-3)! = 15*14*13*12! / 12! = 15*14*13
Step-by-step explanation:
When the seats are empty, there are a total of 15 people that can possibly sit in there. There will only be 1 person left.
When the 1st seat is taken there are now 14 people who can possibly sit on another chair. Same goes when 2 seaats are taken.
To find the total number of possibilities, we multiply together the possible number of people for seat 1, seat2, and seat 3.
Or, if we use stat, nPr = n! / (n-r)!
Meaning:
15P3 = 15!/ (15-3)! = 15*14*13*12! / 12! = 15*14*13
Answer:
Three consecutive numbers are 27,28,29
Step-by-step explanation:
Given : The sum of three consecutive integers is 84.
To find : What are the integers?
Solution : Let three consecutive numbers 
So, according to given situation 'sum of three consecutive integers is 84'.





So,


Therefore, three consecutive numbers are 27,28,29
Only right angles measure 90 degrees.
Given that the table shows the total miles Uyen has run this week.
The image of the table is attached below.
The total distance from the table is 
The total distance this week is 1.5 times the distance that she ran last week.
We need to determine the number of miles that Uyen run last week.
<u>The number of miles Uyen run last week:</u>
Let x denote the number of miles that Uyen run last week.
Let us write the equation from the given data.
Thus, we have;

Dividing both sides by 1.5, we have;

Hence, the value of x is 14.8 miles.
Thus, Uyen ran 14.8 miles last week.
