Question 443443: 1. Sam and Max went to the Taco Barn for lunch. Max paid $2.66 for three tacos and a medium drink. Sam paid $3.70 for five tacos and a medium drink.
a. Use the information provided to write a system of two equations.
b. Use the substitution method to solve the system of equations.
c. How much would the bill be for one taco and one medium drink?
I need to show all work is this right?
3x + y = 2.66 (1) x = tacos, y = drink
5x + y = 3.70 (2)
2x = 1.04
x = 0.52
Sub in 1
3x + y = 2.66
1.56 + y = 2.66
y = 2.66 - 1.56
y = 1.10
Check in (2)
5x + y = 3.70
2.60 + 1.10 = 3.70
x = $0.52 y = $1.10
c. 1.10 + 0.52 = $1.62

Question 447772: Can you please help me solve this absolute value inequality?? :)
| 2x + 1 | + | x - 4 | > 0
my calculations are :
|2x + 1| + |x - 4|>0
|2x+1|>-|x-4|
square both sides
4x^2 + 4x + 1 > x^2 - 8x + 16
...3x^2 + 12x - 15 > 0
(3x+15)(x-1)>0
i use quadratic curve and got x<5 , x>1
