Answer:
Explanation:
at the beginning
number of adults x
number of children y
we have z nb of children and parents leaving
so we can write
y - z = 4 ( x - z)
and y = 2x
so 2x - z = 4x - 4z
3z = 2x
so z = 2x/3 = 2 x 123 /3 = 82
so at the end we have
123 -82 = 41 number of adults
246 -82 = 164 number of children
Calle Ocho is where different ethnic communities wear colors or flags representing pride in their heritage. Flags from Colombia to Nicaragua to Puerto Rico to Costa Rica and even Ireland flood the streets. Foods from different countries are usually sold, and popular music like reggaeton, salsa, bachata and merengue can be heard through the festival.
Sqrt ( 3x^2 + 6 ) = 9
Do the square bothsides of the
Equation.
3x^2 + 6 = 81
3x^2 = 81 - 6
3x^2 = 75
Divide bothsides with 3
3x^2 / 3 = 75/ 3
x^2 = 25
Now ,
x = sqrt ( 25 )
x = + or - 5
But we need pisitive root ,
therefore ,
x = 5
