Responder:
2 1/4 m; 225 cm
Explicación paso a paso:
Dado:
Cortar 9 metros en 4 partes de la misma longitud;
Por lo tanto,
9 metros / 4
= 2,25 metros
Por lo tanto, cada varilla será 2.25 = 2 1/4 m
En cm;
1 m = 100 cm
2,25 metros = x
x = 100 * 2,25
x = 225 cm
Answer:
EK = 9
Step-by-step explanation:
x + 11 = -5 + 2x -5 + 2x
x+11 = -10 + 4x
11 = 3x - 10
3x = 21
x = 7
EK =-5 + 2 × 7
EK = 14 - 5
EK = 9
Divide the amount of teenagers that smoked by the total population:

Multiply this decimal by 100 to convert into a percentage:

To round to the nearest decimal place, look at the hundredths value:
