Answer:
x = 25/3
Step-by-step explanation:
2x-5=20-x
2x-5+5=x+20+5 (add 5 both to both sides)
2x = -x + 25
2x + x = -x + x + 25 (add x to both sides)
3x = 25
3x/3 = 25/3 (divide both sides by 3)
x = 25/3
Answer:
Part 1) The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
Part 2)
Step-by-step explanation:
Part 1)
Let
x-----> the number of pounds of regular coffee
we know that
The inequality that represent the situation is
Solve for x
Divide by 2 both sides
The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
The solution of the inequality is the interval ------> (-∞,7.5]
but the number of pounds cannot be a negative number
therefore
The solution is the interval -----> [0,7.5]
see the attached figure
Part 2) we have
