Question

Gabrielle's age is two times Mikhail's age. The sum of their ages is 45. What is Mikhail's age?

Answer 1

Answer:Gabrielle is 2*Mikhail:

G = 2M We will use this value for G next

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

G+M = 45 Now in this equation substitute for G, like this:

 

2M+M = 45

3M = 45 Divide both sides by 3

M = 15 This is Mikhail, and the problem says that:

G = 2(15) = 30

Gabrielle is 30 and Mikhail is 15, and 15+30 = 45 just like the problem says

Step-by-step explanation:

Answer 2

Answer:

Mikhail's age = 15 years and Gabrielle's ageis 30 years

Step-by-step explanation:

let Mikhail's age be x years

then Gabrielle's age is 2x years

x+2x=45

3x=45

x= 45/3=15 years
