Answer:
x = 
Step-by-step explanation:
12y = 75 + 5x + 2x - 1
combine like terms:
12y = 74 + 7x
subtract 74 from both sides:
7x = 12y - 74
divide both sides by 7:
x = 
Answer:
I'm sorry you got that wrong. The correct answer was R since it is staying in the same place which is called a constant line. It stays in the same place since she isn't moving, she is just standing there waiting for the cab.
So if Angela entered the same restaurant 4 times, we have 4 "instances" of her entering the restaurant.
Each instance, she ordered a salad. The price of this salad is unknown, so we'll say the price is "S".
Each instance, she payed a $5 tip.
So we have 4 instances of spending S, and 4 instances of spending 5.
We know this totals 54.
Knowing all of this information, we can write our equation like this:
4(S + 5) = 54
Divide
S + 5 = 13.50
Subtract
S = 8.50
The cost of salad is $8.50
