Let K and T be the current ages of two siblings Katie and Thomas Katie is currently twice the age of Thomas. In 6 years Katie wi
Alika [10]

Answer:

Here, K represents the current age of Katie and T represents the current age of Thomas.

(a)

As per the statement:

Katie is currently twice the age of Thomas.

⇒K = 2T                ......[1]

It is also given that in 6 years Katie will be 4 times Thomas's current age.

K+6 = 4T

K+6 = 4T

Subtract 6 from both sides we get;

K = 4T-6                    ......[2]

A system of equations that describe the situation is:

K = 2T

K+6 = 4T

(b)

To find the solution:

equate [1] and [2] we have;

4T-6 = 2T

Subtract 2T from both sides we have;

2T-6 = 0

Add 6 to both sides we get;

2T = 6

Divide both sides by 2 we have;

T = 3 years

Substitute this in equation [1] we get;

K = 2(3) = 6 years.

Therefore, the current age of Katie and Thomas are 6 years and 3 years.

You have 65% of your homework left to complete. What decimal and fraction represent the amount of homework you have finished?
Maurinko [17]
Percentage of homework that is left to be completed = 65%
Then
The percentage of homework that is already done = (100 - 65) percent
                                                                           = 35 percent
                                                                           = (35/100)
                                                                           = 7/20
                                                                           = 0.35
So the amount of homework that has already been completed can be represented as 7/20 or o.35. Hope this is the answer you were looking for and i have helped you in this matter. Also i hope the procedure is easy enough for you to understand.
