Answer:
En la última fila de la zona general hay 98 asientos y en la zona preferencial hay 564 asientos.
Explicación paso a paso:
= 1 + − 1 ×
40 = 20 + 40 − 1 × 2
40 = 20 + 39 × 2
40 = 20 + 78
40 = 98
= (1 + ) 2 ×
12= (36 + 58) 2 ×12
12 = 47 × 12
12 = 564

Of means multiplication. So the question is 1/3 X 1 1/2. First make 1 1/2 improper: 3/2. Then multiply the numerators (top numbers) and denominaters (bottom numbers): 1x3=3, 3x2=6, =3/6. Now simplify 3/6=1/2. Then multiply that by 2, since he used 2 pieces: 1/2x2=1. John used 1 meter :)
Answer:
D
Step-by-step explanation:

=
Factor out 2 on the numerator and 2x on the denominator.
= 
Cancel the factor (x + 2) on the numerator/ denominator
=
← cancel the 2 on numerator/ denominator
=
: x ≠ 0
This is a combination problem. The approach to this is by using the nCr method, where n is the number of total objects and r is the number of success. For example, if you want to get 3 red out of the total 4, then that would be 4C3. That means,
4C3 = 4!/3!(4 - 3)! = 4 ways
If you want to get 2 green out of the total 6, then that would be 6C2. That means,
6C2 = 6!/2!(6-2)! = 15 ways
Therefore, there are a total of 4+15 = <em>19 ways</em>.
I think it would be just a constant diagonal line like this /
