Five friends split a $65.20 bill at a restaurant . They also each left $2.75 for the tip. How much money did each person pay in
kvv77 [185]
You start by doing 65.20 (the bill) divided by 5 (the amount of people paying)
65.20 / 5 = 13.04 

Then you add 13.04 (how much each person paid towards the bill) and 2.75 (the amount of money each person left as a tip) 
13.04 + 2.75 = 15.79

Each person paid $15.79

Solve for x. 2x+5+6x-1=120​
svetlana [45]

Answer:

x=14.5

Step-by-step explanation:

2x+5+6x-1=120​

Combine like terms (combine all of the variables and then combine all of the constants)

8x+4=120

subtract 4 on both sides

8x=116

Divide 8

x=14.5

Hope this helps!
