Answer: 5 + j/3
Step-by-step explanation:
Dividing the fare equally
Since they shared the j fare evenly among 3 people, you would divide the j fare by 3 to get j/3
So each person, including Angela, paid j/3 dollars before the tip
Adding the tip
Angela then added 5 dollars to this j/3 so the expression would become 5 + j/3
Final Answer
Angela paid $5 + j/3
-10z+14 would be the simplified answer
Let x represent the first number, y represent the second, and z represent the third.
x + y + z = 92
z = 3x
x = y - 7
Solve x = y - 7 for y.
x = y - 7
x + 7 = y
Fill in y and z so that we only have to worry about x for now.
x + y + z = 92
x + (x + 7) + (3x) = 92
x + x + 7 + 3x = 92
5x + 7 = 92
5x = 92 - 7
5x = 85
x = 85/5
x = 17
Solve for y.
y = x + 7
y = (17) + 7
y = 24
Solve for z.
z = 3x
z = 3(17)
z = 51
So x = 17, y = 24, and z = 51.
