Responder:
2,40
Explicación paso a paso:
Dado que:
Dejar :
Tomate = t
Cebolla = n
(2 kilo de t) + (1 kilo de n) = 8.40
(1 kilo de t) + (2 kilo de n) = 7.80
2t + n = 8,40 - - (1)
t + 2n = 7,80 - - (2)
De (2);
t = 7,80 - 2n
Ponga t = 7.80 - 2n en (1)
2 (7,80 - 2n) + n = 8,40
15,6 - 4n + n = 8,40
15,6 - 3n = 8,40
-3n = 8,40 - 15,6
-3n = - 7,2
n = 2,4
t = 7,80 - 2 (2,40)
t = 7,80 - 4,80
t = 3
Por lo tanto, el costo de 1 kilo de cebolla es 2,40
Answer:
Natalie's age is 14
Sasha's age is 17
Step-by-step explanation:
Let
Sasha's age be "s", and
Natalie's age be "n"
<u>Sum of Sasha and Natalie is 31:</u>
s + n = 31
<u>Twice Natalie is 11 more than Sasha:</u>
2n = s + 11
We ca solve this equation for s first:
s = 2n - 11
We put this into first equation and solve for n first:
s + n = 31
2n - 11 + n = 31
3n = 31 + 11
3n = 42
n = 42/3 = 14
Natalie's age is 14
Also, s = 2n - 11
s = 2(14) - 11
s = 28 - 11
s = 17
Sasha's age is 17

Answer:
-3*3=-9
Step-by-step explanation:
Tigers: 1 - 2/3 = .3333
Redbirds: 1 - 4/5 = .2
Bulldogs: 1 - 3/8 = .625
Titans: 1 - 1/2 = .5
The Redbirds likelyhood is lowest, therefore, they're least likely to play I'm the championship.
B is the correct answer.
