Explicación paso a paso:
Como no dijimos qué calcular, también podemos encontrar el tiempo que tarda el automóvil en viajar por la carretera.
Velocidad = Distancia / Tiempo
Tiempo = Distancia / Velocidad
Dado
Distancia = 200 km
Velocidad = 120 km / h
Sustituir
Tiempo = 200/120
Tiempo = 20/12
Tiempo = 1,67 horas
Por tanto, el tiempo que tarda el coche en recorrer la carretera es de 1,67 horas.

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define</u>
y = x - 15
y = 4x
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x = x - 15
- [Subtraction Property of Equality] Subtract <em>x</em> on both sides: 3x = -15
- [Division Property of Equality] Divide 3 on both sides: x = -5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = 4x
- Substitute in <em>x</em>: y = 4(-5)
- Multiply: y = -20
Answer:
(cos(π) sin(π))/(2 5) + (cos(π) sin(π))/(5 2) = 1/5 cosh(i π) cos(-π/2)
