Let the marks of Devi be x and Ali be y.
So, the equations:
2y = x <em>and</em> y + 16 = x
So,
2y = y + 16. [ because we know equals are equal to equals]
=> 2y - y = 16
=> y = 16
Check
Ali's marks are half of Devi's marks.
Devi's marks are 16 more than alis.
So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).
Sum is
r=common ratio
a1=first term
it looks like 2^0=1 is the first term aka a1
it goes to the 9th term (2^9)
sub
The sign would be negative
X is in the negative area meaning that when x/y and multiplied by y, it would stay negative since y is positive
Answer:
La familia de Gonzalo ha despilfarrado 15,768 litros de agua.
Step-by-step explanation:
Dado que Gonzalo observa que el grifo del lavabo gotea luego de un año, y el goteo se produce una velocidad de una gota por segundo y cada gota contiene 0.5ml de agua, para determinar cuántos litros de agua ha despilfarrado la familia de Gonzalo desde que ellos se dieron cuenta de la avería se debe realizar el siguiente cálculo:
1 año = 365 dias x 24 horas x 60 minutos x 60 segundos
0.5 x 60 x 60 x 24 x 365 = X
30 x 60 x 24 x 365 = X
1800 x 24 x 365 = X
43,200 x 365 = X
15,768,000 = X
15,768,000 / 1000 = X
15,768 = X
Por lo tanto, la familia de Gonzalo ha despilfarrado 15,768 litros de agua.
Answer:
10x - 17
Step-by-step explanation:
Perimeter is the sum of all sides
5x - 7 + (3x - 4) + (2x - 6)
10x - 7 - 4 - 6
10x - 17
