Jim, Carla and Tommy are members of the same family. Carla is 5 years older than Jim. Tommy is 6 years older than Carla. The sum of their three ages is 31 years. How old is each one them?

Answers

Answer 1

Answer: So,

We'll solve it with only one placeholder, since that's simpler.

Jim's age = J
Carla's age = C
Tommy's age = T

J = base
Carla's age = J + 5
Tommy's age = Carla's age + 6 or J + 5 + 6 or J + 11

Sum of ages = 31
(J) + (J + 5) + (J + 11) = 31

3J + 16 = 31

Subtract 16 from both sides
3J = 15

Divide both sides by 3
J = 5

Carla's age = J + 5
Carla's age = 10

Tommy's age = Carla's age + 6
Tommy's age = 10 + 6 or 16

5 + 10 + 16 = 31
15 + 16 = 31
31 = 31 This checks.

Jim is 5.
Carla is 10.
Tommy is 16.

Answer 2

Answer: lets
Jim x years old
Carla (x+5) years old
Tommy (x+5)+6 years old
sum is x+(x+5)+(x+5)+6=31 years old
3x+16=31
3x=15
x=5 - age of Jim
x+5=5+5=10 - age of Carla
x+5+6=16 - age of Tommy
Answer: 5, 10 and 16 y.o

Samuel will arrive at the airport on the first plane after 10 A.M. Airplanes arrive every 50 minutes beginning at 6 A.M. When will Samuel's plane arrive?

Answers

The plane Samuel's will arrive at 10:10 AM if Samuel arrives at the airport on the first plane after 10 AM, Airplanes arrive every 50 minutes beginning at 6 AM.

What is multiplication?

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

Samuel will arrive at the airport on the first plane after 10 A.M,

Airplanes arrive every 50 minutes beginning at 6 A.M.,

Calculate the time of Samuel's plane as shown below,

The total time = 10 - 6 = 4 hours

The total time = 4 × 60 = 240 minutes

If the plane is coming in every 50 minutes, then the 5th plane will come at 5 × 50 = 250 minutes

Thus, the plane Samuel's will arrive at 10:10 AM.

In the 1st generation, there are 3 rabbits in a meadow.

Answers

Answer: Option C

$a_n=3(6)^(n-1)$

Step-by-step explanation:

The number of rabbits in each generation can be modeled using a geometric sequence of the form:

$a_n=a_1(r)^(n-1)$

Where $a_1$ is the first term of the sequence, $a_n$ is the ninth term of the series, r is the common ratio

To find the proportion we divide the consecutive terms of the sequence as shown

$(18)/(3)=6\n\n(108)/(18)=6$

Then the common ratio is: $r=6$

The first term of the series is: $a_1=3$

Then the explicit formula is:

$a_n=3(6)^(n-1)$

The answer is: Option C

Answer: I think the answer is C.

Step-by-step explanation:I don't really know how to explain but I think that's correct.

The start time is 11:00 and the Elapsed time is 4 hours 5 minutes so what is the End time?

Answers

In 24 hour time: 15:05
In 12 hour time: 3:05

The end time is 3:05. Since it's 11:00, and 4 hours and 5 minutes have passed, just add 4:05 to 11:00. Because there are 12 hours in a day, we go from 11:00 to 12:00 to 1:00 to 2:00 to 3:00 when we add 4 hours.

11:00 + 4:05 = 3:05

Hope this helps!
