The average weight of the whole class is 48 kg.
The average weight of the girls is 42 kg.
We can build the equiation as :
(42 + X) / 2 = 48
Then we clear the X and do the operations :
42 + X = 48 * 2
X = 96 - 42
X = 54
We can asumme the average weight of the boys is 54 kg.
Tiene 3 dígitos y se debe sumar con ON de 2 dígitos para obtener un resultado ROAD de 4 dígitos. Por tanto el único valor de T = 9. Ejemplo : ON 36 + THE + 985 - - - - - - - - - - - - - - ROAD 1021. Ahora el valor…
El resultado es positivo ( - )( - )( - )( - ) = +.
739 if we round up the numbers after the comma i believe.
