Answer:
Ava is 26 and Grace age is 9
Step-by-step explanation:
x=ava's age
y=grace's age
3y-1=x
x+y=35
Substitute 3y-1 to x+y=35 for the value of x to find grace age
3y-1+y=35
4y-1=35
+1 +1
4y=36
y=9 now substitute 9, the y value in 3y-1=x to find ava's age
3(9)-1=x
x=26
to verify; 26+9=35
true 35=35

Step-by-step explanation:
so 1/5 means there are 5 peice to make a whole...
so if you cut an apple into 5 parts, each slice of that apple is 1/5
so if you cut 9 apples into 5 slices its just multiplication...
5*9=45
**for my visual learners** in the parenthesis are groups of 5 sticks
( ///// ) **those are your apple slices** **now just do that exactly 9 times**
( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// )
5 10 15 20 25 30 35 40 45
i really hope this helps <3
