Question

Mia is three years older than twice her sister Brooke's age. The sum of their ages is less than 30. What is the greatest age Brooke could be?
(Points : 1)
a.)7

b.)8

c.) 9

d.)10

Answer 1

I think 8

Answer 2

y

Answer 3

Let Mia's age be m and her sister's age be x
m=2x+3
2x+3+x=less than 30
For greatest age we need to take largest number.
3x+3=29
x=26/3
But the options are all in whole numbers, so if
3x+3=27
then x =8

Answer 4

LET HER SIS AGE BE x then mia=3+2x....x+(3+2x)=30 therefore....3x+3=30..... 3x=27...x=27/3.... x=9

Answer 5

x=9
