Answer:
The individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Step-by-step explanation:
First we have to find 2 equations to express the problem
x = value of each item
y = total amount of money
3x = y
4 ( x - 2.25 ) = y
we replace the y by (3x) in the second equation and obtain the value of x
4 ( x - 2.25 ) = y
4 ( x - 2.25 ) = 3x
4x - 9 = 3x
4x - 3x = 9
x = 9
9 - 2.25 = 6.75
this means that the individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Answer:
3,267
Step-by-step explanation:
Fro the statement you can write the following equations:
x+y= 4,356 (1)
y= 3x (2)
x= afternoon perforance
y= evening perforance
Then, you can replace 2 in 1 and isolate x:
x+3x= 4,356
4x= 4,356
x= 4,356/4= 1,089
y= 3x= 3(1,089)= 3,267
According to this, the answer is that for the evening performance 3,267 tickets were sold.
First you find the median, the middle term (if there are an even number of terms it is the average of the middle two terms.) Since you have 21 terms, odd, you just use the middle term, in this case 8. The first quartile works the same way, but just on the left half between the start and the median...so the first quartile is 6.
To get miles per hour, divide the miles by the hour = 0.266 or 0.03
4/5 divided by 30(half hour)
I hope that help
