Sagot :

apologiabiology
jill=j
meg=m
beth=b
jill is 2 years younger than meg
therefor if we add 2 to jill age we get meg's age
j+2=m
beth is 1/2 as old as meg
therefor 1/2 of megs age=beth's age
b=1/2m

j+2=m
b=1/2m

Answer:

The algebraic expressions are

x = m + 2

[tex]y = \frac{m}{2}[/tex]

Step-by-step explanation:

As given

Jill , meg and Beth are sisters.

Let m is represented the age of the meg.

Let x is represented the age of the jill.

Let y is represented the age of the Beth.

As given

Jill is 2 yrs younger than meg .

Thus

x = m + 2

As given

Beth is half as old as meg.

Thus

[tex]y = \frac{m}{2}[/tex]

Therefore the algebraic expression are

x = m + 2

[tex]y = \frac{m}{2}[/tex]
