Hi there, Kevin's age would be C. 7. This is because Tonya right now is 14. 7 is half of 14.

For this case we have the following variables:


T: Tonya's age


K: Kevin's age


If Tonya is twice Kevin's age we have:


T = 2K

In three years Tonya will have 17, it means:


T +3=17

We have a system of two equations with two unknowns:

T=2K

T+3=17

From the second equation we have:T = 17-3 = 14

Substituting T = 14 in the first equation we have:


14 = 2K

Clearing K:


\frac{14}{2}=K

So, Kevin is 7 years old


Answer:


7 years


Option C

How to break down 4/5 + 13/15 = 1 2/3
nalin [4]

Answer:

Step-by-step explanation:

The left hand side of the equation contains proper fractions while the right hand side of the equation contains mixed fraction. The mixed fraction can be changed to improper fraction. 1 2/3 becomes 5/3

To breakdown the left hand side of the equation, we would take lowest common factor of 5 and 15. It is 15

Considering 4/5, if 15 divides 5,the result is 3. Multiplying 3 by 4 gives 12. So it becomes

12/15

Considering 13/15, if 15 divides 15,the result is 1, Multiplying 1 by 13 gives 13. So it becomes

13/15

The equation becomes

(12 + 13)/15 = 5/3

25/15 = 5/3

Simplifying 25/15 to its lowest terms, it becomes 5/3 so

5/3 = 5/3
