Answer:

<u>Se contagiarian 160 personas.</u>

Step-by-step explanation:

Para este problema debenos usar la siguiente regla de tres:

$\frac{10(personas)}{4(enfermas)}=\frac{400(personas)}{x(enfermas)}$

Ahora, debemos despejar x de la ecuacion de arriba.

$x=\frac{400(personas)*4(enfermas)}{10(personas)}$

$x=160(enfermas)$

<u> Por lo tanto, se contagiarian 160 personas.</u>

Espero te haya sido de ayuda!

blagie [28]

Answer:

d. 23

Step-by-step explanation:

x: small hat

y: medium hat

z: large hat

We now write the system of equations:

x + y + z = 47

5.50x + 6y + 7z = 302

-3x + y = 0

We can write the system in matrix form as:

Ax = b

Where,

A = [1 1 1; 5.50 6 7; -3 1 0]

b = [47; 302; 0]

x = [x; y ; z]

Solving the system we have:

x = 6

y = 18

z = 23

hope this helps
