Anna is three times as old as Diane. If the sum of their ages is 44, how old is Anna?

So Anna is 30.

Step-by-step explanation:

So Anna is 3 times as Diane and together they are 44.

Do 44/3 which equals 14.667. So Diane is 14.

Next 44-14 = 30

--> 14.667x3 which equals 44.001. SO that proves that Anna is 3 times the age of Diane...

Some of this work has been rounded so I'm hoping you weren't supposed to use decimals cause I rounded.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
