Answer:
15 business class and 12 economy class
Step-by-step explanation:
Let the x be the number of business class. y be the number of economy
x + y = 27 ...............(a)
700x + 375y = 15000 .............(b)
Multiply first equation by 700
700*x + 700*y = 700*27
700x + 700y = 18900 ...............(c)
Recall:
700x + 375y = 15000 .............(b)
-
700x + 700y = 18900 ...............(c)
____________________________
0 -325y = -3900
y = -3900/-325 = 12
Recall x + y = 27, x + 12 = 27, x = 27 - 12 = 15
the answer is 15 business class and 12 economy class
Alright rounding is really easy! So to round, you look at the number right before the one you want to round to. In this case, you want to round to the nearest 10,000 so in 4,719,429 you look at the nine. If that number is bigger than 5 you rounds up. 9 is bigger than 5, so it rounds to
4,720,000
Answer:
Infinite solutions
Step-by-step explanation:
x + y = 10
y = -x + 10
We'll choose one equation to use, x + y = 10
Substitute y with -x + 10
x - x + 10 = 10
x cancels each other out
10 = 10, which would also mean 0 = 0
This means the answer will validate with any number
