Sienna has $8 and is saving $3 per week. Jacob has $6 and is saving $4 per week. Which model represents the equation that can de
8090 [49]

Answer:

B

Step-by-step explanation:

From the given information:

Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.

This implies that:

8x + 3(1) = 8x + 3

Also,

If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;

i.e.

6(x) + 4(1) = 6x + 4

So;

the model that can determine when Sienna will have the same amount as Jacob is:

8x + 3 = 6x + 4

Sati [7]

Pregunta completa:

Al llegar al hotel nos an dado un mapa con los lugares de la ciudad nos dijieron que 5 cm del mapa que representaban 600 metros de la realidad hoy queremos ir a un par que que se encuentra a 8 cm del hotel en el mapa. ¿A qué distancia del hotel está la pareja?

Respuesta: 960m

Explicación paso a paso:

Dado que:

5 cm en el mapa equivale a 600 m en tierra Por lo tanto,

8 cm en el mapa será equivalente a:

5 cm en el mapa - - - - - -> 600 m en el suelo 8cm - - - - - - -> y metros en el suelo

Usando la multiplicación cruzada

y × 5 = 8 × 600

5y = 4800 Luego,

y = 4800/5

y = 960m

Por lo tanto, 8 cm en el mapa serán 960 m en realidad.
