Question

Maria is x old her sister is twice her age write an expression in simplest form that represents the sum of the ages of the two sisters

Answer 1

x*2=y+x= both

Explanation:

y would be her sister age, you would have to multiply Marias age by 2 to get her sisters age since her sister is twice her age then you have to add them together to get the sum of both their ages.

Example: maria is 16

16*2=32+16=48

so the sum of both of their ages is 48 (JUST AN EXAMPLE)
