We can represent this situation by the equation 2x+4x+5x=33.

Then 11x=33, and x = 3.  

Then the children's ages are in the ratio 2x:4x:5x, or 2(3):4(3):5(3), or

6:12:15.

Do these 3 ages add up to 33?  6 + 12 + 15 = 33?  YES!

The children's ages are 6, 12 and 15 years respectively.

Step-by-step explanation:

let the given ages be 2x , 4x and 5x.

Here,

2x + 4x +5x =33

or,x = 33/ 11

or,x =3

Hence,

2x =2 (3)=6years

4x=4(3)=12years

5x=5(3)=15years

Determine whether the following sequence is arithmetic, geometric, or neither.

Answer:

arith

Step-by-step explanation:

Let's check whether or not this is a geometric series.

The first term is 1 1/3, or 4/3.

What would the common ratio be, to convert this 4/3 into the 2nd term, 2?

(4/3)r = 2, or r = 2(3/4) = 6/4 = 3/2.

Assuming that the common ratio is r = 3/2, will multiplying 2 by 3/2 result in the 3rd term, 2  2/3?  NO.  So this is NOT a geometric progression.

The difference between 1  1/3 and 2 is 2/3.  If we add 2/3 to 2, we get 2  2/3, which agrees with the given 3rd term.  

If we add 2/3 to 2  2/3, do we get the fourth given term, 3  1/3?

2/3 + 2  2/3 is equivalent to 2  4/3, or 10/3, which is equivalent to 3  1/3.

Thus, this IS an arithmetic sequence, and the common difference is 2/3.

What is the product? Enter your answer as a fraction, in simplified form, in the box. 38⋅(−36)
valina [46]
If you multiply 38*(-36) you would get -1368. And to convert that into a fraction it could be -1368/1, -13680/10, etc.
