3.6 simplifies to 36/10
and to make that a mixed number
3 and 6/10
simplify that and you get
3 and 3/5
Hope this helped!
He can split his pop into in whole mLs any n glasses such that n is a divisor of 30, namely any n in {1,2,3,5,6,10,15,30}. The fraction in each glass is then 1/n.
Step-by-step explanation:
a. we simply subtract 3. from 2.
x + 2y + z = 15
- -3x + y + z = 2
--------------------------
4x + y 0 = 13
b. we multiply 3. by 3 and then subtract from 1.
2x - 4y + 3z = -7
- -9x + 3y + 3z = 6
-----------------------------
11x - 7y 0 = -13
c. we multiply the result of a. by 7, and then simply add a. and b., because the y terms have different signs already.
28x + 7y = 91
+ 11x - 7y = -13
--------------------------
39x 0 = 78
39x = 78
x = 2
d. we use this x = 2 in the result of a.
4×2 + y = 13
8 + y = 13
y = 5
e. using x = 2 and y = 5 in 2.
2 + 2×5 + z = 15
2 + 10 + z = 15
12 + z = 15
z = 3
the solution is therefore (2, 5, 3).
Answer:
386 passengers arrive at Estados Unidos.
386 pasajeros aterrizará en Estados Unidos.
Step-by-step explanation:
English Translation
A plane from Córdoba bound for Estados Unidos and makes stops in Chile and Bolivia. The plane has a capacity for 507 passengers. He leaves the Córdoba airport with 119 empty seats. In Chile 33 passengers go down and 121 go up. In Bolivia 129 go down and 39 go up. How many arrive in Estados Unidos?
- The plane has capacity for 507 passengers.
- 119 seats are empty when it leaves Córdoba.
Meaning that there were (507 - 119) passengers on board = 388 passengers
- In Chile 33 passengers go down and 121 go up.
Number of passenger become
388 - 33 + 121 = 476 passengers
- In Bolivia 129 go down and 39 go up.
Number of passengers become
476 - 129 + 39 = 386 passengers.
