When making a long distance call from a certain pay phone, the first three minutes of a call cost $2.10. After that, each additi
Sauron [17]

Answer: the number of minutes of long distance call that one can make is lesser than or equal to 12 minutes.

Step-by-step explanation:

Let x represent the number of minutes of long distance call that one makes.

The first three minutes of a call cost $2.10. After that, each additional minute or portion of a minute of that call cost $0.45. This means that if x minutes of long distance call is made, the total cost would be

2.10 + 0.45(x - 3)

Therefore, the inequality to find the number of minutes one can call long distance for $6.15 is expressed as

2.10 + 0.45(x - 3) ≤ 6.15

2.10 + 0.45x - 1.35 ≤ 6.15

0.75 + 0.45x ≤ 6.15

0.45x ≤ 6.15 - 0.75

0.45x ≤ 5.4

x ≤ 5.4/0.45

x ≤ 12

What did I do wrong I really need help!!!!!!!!!!!!!!!!!!!
Leviafan [203]
In algebra it is fully possible for x to equal to zero. After you have 2x, just divide both sides by two, so it would be 2 divided by 0 and than you would have x=0 and that would be your final answer.

2x + 1 = 4x +1
-2x +1 = 1
-2x = 0
divide by -2
x=0

suter [353]

Answer:

Step-by-step explanation:

<u>Given ratio</u>

  • 1/8 pound ⇔ 25 square feet

<u>To find </u>

  • x ⇔ 1 square foot

<u>Divide both sides by 25</u>

  • 1/8÷25 pounds ⇔ 25÷25 square feet
  • 1/200 pounds ⇔ 1 square foot
