Answer:



Step-by-step explanation:
Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so

An aircraft has a maximum of 220 economy seats

A flight will be cancelled if the money taken for the seats is less than $28,800.
so

therefore
Three inequalities that represent the situation are



Ok so $2.05 + $15 = $17.05 so you want to try to spend the same amount of money in each store so what have to do is figure out the number of gallons you buy in each store i added 2 gallons for the first store so the amount would be $2.05(2) + $15= $21.15 so now to find the x in the next equation you have divide the sum by $2.35 which give you 9 gallons now you spent the same amount in each store so you paid for 11 gallons hope you give me brainliest answer lol
Some of the answers are going to be negative fractions, and some are going to be positive. I can't show the work on here right now but I hope that this helped a little bit. If you have any further questions then let me know and I can try to help you!
Answer:
2.25 and 4.95
Step-by-step explanation:
x + y = 7.2
x - y = 2.7
x = 7.2 - y
x - y = 2.7
(7.2 - y) - y = 2.7
7.2 - 2y = 2.7
-2y = 2.7 - 7.2
-2y = -4.5
-2y/-2 = -4.5/-2
y = 2.25
x + y = 7.2
x + 2.25 = 7.2
x = 7.2 - 2.25
x = 4.95
Check: 4.95 and 2.25
x + y = 7.2
(4.95) + (2.25) = 7.2
7.2 = 7.2
x - y = 2.7
(4.95) - (2.25) = 2.7
2.7 = 2.7

Answer:
trisect the median. The centroid is 1/3 its length from the side.
Step-by-step explanation:
The centroid divides each median into parts with a ratio of 2:1. If you trisect the median, the centroid will be 1 unit from the side and 2 units from the vertex.
