Answer: 1. X+2
2. 6x-3
3. -2x-1
4. 9x5
Step-by-step explanation:
1. X+4-3+1 There is only one variable, so you don’t need to worry about that. Just do all of the numerical operations. 4-3+1= 2. So it would be x+2
2. X-5+5x+2. Again, do the numerical operations first. -5+2=-3. X+5x=6x. So it would be 6x-3.
3. 2x+7-4x-8. 7-8=-1. 2x-4x=-2x. So it would be -2x-1.
4. (4+3)x+2x-5. Do the operation in the parenthesis first. Then it would be (7)x or just 7x+2x-5. Simplify to 9x-5.

Answer:
Each person would pay $15.71
Step-by-step explanation:
First we can calculate how much everyone ate by multiplying the bill amount by 120% (20% tip and 100% of the bill).
$52.35 * 120% = $62.82
Now to find out how much each pays, we have to divide that cost by the number of people (4).
$62.82/4 = $15.71
