It is 35/21 it shows that is can turn into a mixed number as well
Check the picture below.
so, the maximum height is reached at the parabola's vertex, where x = how many seconds it took, y = how hight it went.

Answer:
x = 9
Step-by-step explanation:
6x = 54
Simple way of solving, all you have to do is isolate the variable "x." To do that, divide the number, 6, by both sides.
6x / 6 = 54 / 6
54 / 6 = 9
Hence,
x = 9
Hope this helps :)
Por un sistema de ecuaciones, tiene-se que:
- Cada lapiz cuesta 20 ptas.
- Cada boligrafo cuesta 50 ptas.
-------------------------
- Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.
- <u>Boligrafo cuesta 30 mas que un lapiz</u>, o sea,

- <u>8 boligrafos y 15 lapices cuesta 700</u>, o sea,

-------------------------
- Aplicando el <u>primer ecuación en la segunda, </u>tiene-se el cuesto de cada lapiz:






Cada lapiz cuesta 20 ptas.
-------------------------
Por fin, el cuesto de cada boligrafo es dado por:

Cada boligrafo cuesta 50 ptas.
