Answer: (3y) + 7+x
Step-by-step explanation:
You just flip and then their equivalent
Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
Im not sure this is right but i think they will meet during 12 minutes
2.25t+5= 13.5t+14
-2.25t -2.25t
5= 11.25t+14
-14 -14
-9= 11.25t
-9/11.25=t
t= -0.8
Answer:
3 5/6 + (-11/6) --> 2 2/3
Step-by-step explanation:
Step 1: 3-1--> 2
Step 2: 5/6 - 1/6 --> 2/3
Final Answ. : 2 2/3
