Las edades de dos hermanos tienen una razón de 2 a 1. Cuando transcurran 4 años, la razón entre sus edades será de 8 a 6. ¿Cuánt
Nataly [62]

Answer:

The age of brothers are 4 years and 2 years respectively.

Step-by-step explanation:

We are given that the ages of two brothers have a ratio of 2 to 1. When 4 years have passed, the ratio of their ages will be 8 to 6.

Let the age of the first brother be 'x years' and the age of the second brother be 'y years'.

So, according to the question;

  • The first condition states that the ages of two brothers have a ratio of 2 to 1, that means;

                                      \frac{x}{y} =\frac{2}{1}  

                                      x=2y  -------------- [equation 1]

  • The second condition states that when 4 years have passed, the ratio of their ages will be 8 to 6, that means;

                                       \frac{x+4}{y+4}=\frac{8}{6}

                               6({x+4})=8}(y+4)

                               6x+24=8y+32

                               6(2y)+24=8y+32

                               12y-8y=32-24

                                    4y=8

                                     y=\frac{8}{4} = 2 years

Putting the value of y in equation 1 we get;

                                     x = 2y

                                      x = 2 \times 2 = 4 years

Hence, the age of brothers are 4 years and 2 years respectively.

Nd the 52nd term and the term named in the problem <br>40, 140, 240, 340, ...<br>Find a 32​
Galina-37 [17]

Answer:

5140 and 3140

Step-by-step explanation:

Note there is a common difference d between consecutive terms in the sequence, that is

d = 140 - 40 = 240 - 140 = 340 - 240 = 100

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 40 and d = 100, thus

a_{52} = 40 + (51 × 100) = 40 + 5100 = 5140

a_{32} = 40 + (31 × 100) = 40 + 3100 = 3140
