3) Margarita manejó 429 km: 42 en la ciudad y el resto, en la autopista.
12345 [234]

Answer:

Margarita gastó <u>$40.43.</u>

Step-by-step explanation:

Tenemos la siguiente información.

<u>km recorridos por Margarita</u>

42 km - ciudad

387 km - autopista

<u>Rendimiento del carro</u>

1 galon cada 28 km - ciudad

1 galon cada 36 km - autopista

Hacemos el siguiente factor de conversión

<u>Ciudad</u>

42 km \times \frac{1\: galon}{28\: km}=1.5\: galones

<u>Autopista</u>

387 km \times \frac{1\: galon}{36\: km}=10.75\: galones

Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:

Total galones = 1.5 + 10.75 = 12.25 galones

Total costo = 3.30*12.25 = $40.43.

Solve the system of equation using subtraction 3x+2y=7 y=-3y+11
forsale [732]
Assumig 2nd euqation is y =-3x+11
using subtraction

minus y both sides and minus 11
-3x-y=-11

add to other equation to eliminate  y's

-3x-1y=-11
<u>3x+2y=7 +</u>
0x+1y=-4

y=-4


sub back


y=-3x+11
-4=-3x+11
minus 11 both sides
-15=3x
divide both sides by 3
-5=x
