8 costumes. Not 8/0.75.
Write down 8 costumes, that's your answer.
(x/2 - 3) - (4x^2 + x - 4)
(x/2 - 3) - (16x + x - 4)
(1/2x - 3) - (17x - 4)
-16.5x - 1
I believe that is the correct answer.
Answer:
Leila's call lasted for 25 minutes.
Step-by-step explanation:
inital amount - (0.22 * minutes on the phone) = final amount
25 - 0.22x = 19.5
Solve for x
Subtract 25 from both sides
-0.22x = -5.5
Divide both sides by -0.22
x = 25
