Step-by-step explanation:
Here is the complete question:
Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the $j fare among the 3 of them. Angela also paid a $5 tip. How much did Angela pay in total?
Write your answer as an expression.
Answer:
From the question, we are told that Angela shared a cab with her friends and when they arrived at their destination, they shared equally the $j fare among the 3 of them while Angela also paid a $5 tip.
The total number of friends are =3
The amount of fare = $ J
The fare is equally divided among the friends, therefore each friend will pay: $J/3
Angela paid $5 additional as a tip, therefore, her share will be: J/3 + 5
Therefore, Angela will pay $J/3 + $5
Answer:
-27/7
Step-by-step explanation:
Replace x with 19,
f(19)=3/(19+2) - root(19-3)
=3/21 - root(16)
=1/7 - 4
=1/7 - 28/7
= -27/7
