For number 13,the arrow should be going “<“ way because it is in fraction form and the bigger the number the smaller the pieces. This repeats for the rest of the questions so for number 14,the answer is “=“,and for number 15 it is “>”
I believe the first one is c
its y-axis for the first answer and the other one its, y=-x
Answer:
Eleana is 20 years old.
Her grandfather is 80 years old.
Step-by-step explanation:
Suppose Eleana's age is "x". That means her grandfathers age is 4x.
x+4x= 100
5x=100 Divide both sides by 5
x=20 That means Eleana is 20 years old.
Her grandfather would be 4 times her age so his age would be 40 years old.
