Alright, so he went the same distance there and back, but at different speeds
hmm
d=st
d/s=t
total time is 9.5hr
alright
so distance there=distance back we will call both of them d
so
speed there is 10
speed back is 9
total time is 9.5
so
d/sthere+d/sback=totaltime
d/10+d/9=9.5
times both sides by 90
9d+10d=855
19d=855
divide both sides by 19
d=45
he can ride 45mi away
La ecuación de la linea es: y = -4x + 2600
<h3>
¿Como determinar la relación lineal?</h3>
Tenemos dos puntos para nuestra linea, los cuales son (350, 1200) y (320, 1320).
Con esos dos puntos podemos obtener la pendiente de la linea:

Entonces la linea es algo como:
y = (-4)*x + b
Para obtener el valor de b usamos uno de los dos puntos dados, como el primero:
1200 = (-4)*350 + b
1200 = -1400 + b
1200 + 1400 = b = 2600
Entonces la linea es:
y = -4x + 2600
Si se vendieron 35 unidades, podemos reemplazar:
35 = -4*x + 2600
4x = 2600 - 35 = 2565
x = 2565/4 = 641.25
Es decir, el precio es $641.25

Answer:
1/18 ?
Step-by-step explanation:
I'm not sure if you're written the whole question?
3 pans with 6 muffins in each pan, so total number of muffins = 3 x 6 = 18
So each muffin is 1/18
