Answer:
-18
Step-by-step explanation:
This is rather simple is it not?
To find the difference between the numbers, we simply have to subtract one from another. , which can be simplified into because subtracting a negative from a negative is simply done by adding the second negative as a positive to the first negative. Therfore = -18 which is your answer.
-18 is how much each number is subtracted to get the next.
Answer:
-4
Step-by-step explanation:
-2+1= (-1) x (-1) =1 + (5x12)*60* divided by (5x3)*15* =5 -9 = -4

Responder:
1 hora 55 minutos; 22 horas 45 minutos
Explicación paso a paso:
Dado que:
Tiempo el primer día = 15 minutos
Minutos adicionales cada día siguiente = 5 minutos
Número total de días
Usando la fórmula del enésimo término de una progresión aritmética:
Tn = A + (n - 1) d
A = primer trimestre = 15
d = diferencia común = 5
n = enésimo término
Tiempo de nado el último día (n = 21)
T21 = 15 + (21 - 1) 5
T21 = 15 + 20 * 5
T21 = 15 + 100
T21 = 115 minutos
= 1 hora 55 minutos
SEGUNDO.)
Suma de minutos durante las 3 semanas
Suma de n términos:
Sn = n / 2 * (primer término + último término)
Primer término = 15
Último trimestre = a21 = 115 minutos
n = número de términos = 21
Por lo tanto,
Sn = 21/2 * (15 + 115)
Sn = 10,5 * (130)
Sn = 1365 minutos
= 22 horas 45 minutos
