Well Briana would have finished at 10.63 seconds (meaning she would have won XD)
Three-tenths can also be expressed as 0.3, and 0.3 + 12.08 is 12.38.
Hope this helps!! <3

Let x be the total price. And you paid 75% of it which is $135.

x * 75/100 = 135
x = 180

se vendieron 144 boletos. 2 pesos por adulto y un peso por niño, si se gastaron 207 pesos cuantos boletos de adulto se vendieron
natulia [17]

Answer:

Se vendieron 81 boletos de niños y 63 boletos de adultos.

Step-by-step explanation:

La cantidad de boletos vendidos es igual a:

144 = a + n   (1)

En donde <em>a </em>es por adultos y <em>n</em> por niños

A su vez, el dinero gastado equivale:

207 = 2*a + 1*n   (2)

Resolviendo la ecuación (1) para <em>a:</em>

a = 144 - n   (3)

Introduciendo (3) en la ecuación (2) tenemos:

207 = 2*(144 - n) + n

n = 81

Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo <em>n</em> en la ecuación (3):

a = 144 - n = 144 - 81 = 63

Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.  

Espero que te sea de utilidad!

STALIN [3.7K]

Answer:

Both are correct. Either rule applied first will have the same result. Both rules will be used either way, and the order in which they are applied does not matter as long as they are applied correctly at each step.
