on call 3.5 hour $10 talk time 1/2 hour $1.25 what is the unit rate in dollar per hour for each company

Answers

48. On call = 3.5 hours for 10 dollars=> ½ hour for 1.25 dollars.Now, let’s solve the unit rate for each companyfirst = 3.5 hour / 10 dollars=> 10 / 3.5=> Unit rate is 2.9 dollars/hrSecond company = ½ hour for 1.25 dollars=> 1.25 / .5=> 0.25 dollars / hr.Thus, the first company pays better than the second one because it pays 2.9 dollars every hour of talk compare to the 2nd one which pays only 0.25 dollars per hr.

a pizza place charges $15 for a pepperoni pizza and $12 for a cheese pizza. the goal is to sell $540 in pizza for the day. The situation can be represented by the equation 15x+12y=540, x=pepperoni pizzas and y= cheese pizzas. If the pizza place runs out of pepperoni, how many cheese pizzas must be sold to reach the daily goal?

Answers

Answer:

$45

Step-by-step explanation:

540 divided by 12 = y

8 pencels cost 3.44 whates the unit rate of one pencil

Answers

The unit rate of one pencil is $0.43
3.44/8=0.34

One pencil costs $0.43, you just divide 3.44 by 8

Which is an equivalent form of the compound inequality −44 > −2x − 8 ≥ −8?

Answers

Answer:

An equivalent form of the compound inequality is the pair of single inequalities:

  • -2x - 8 < - 44, and
  • −2x − 8 ≥ −8

Explanation:

You can split the compound inequality into two equivalent inequalities by taking each side from the variable.

The compound inequality −44 > −2x − 8 ≥ −8 means that two conditions must be satisfied:

    1. From the left side: - 44 > - 2x - 8

    2. From the right side: −2x − 8 ≥ −8

Then, as a first approach you can tell that an equivalent form of the compound inequality is the pair of single inequalities:

  • -44 > -2x - 8, and
  • −2x − 8 ≥ −8

You should put the variable on the left sides, which will yield the best form of an equivalent pair of inequalitis.

  • - 2x - 8 < -44, and
  • - 2x - 8 ≥ - 8

That is the best choice of an equivalent form, and from there you can solve the inequalities which will permit to obtain the solution. Of course, you can manipulate the variable and find many other equivalent forms.

Notice, that both inequalities must be satisfied simultaneously.

This is how you solve that system

  • - 2x - 8 < -44n

        Add 8 to both sides: - 2x < -36

         Divide both sides by - 2 (you have to change the sign): x > 18

  • - 2x - 8 ≥ - 8

-

        Add 8 to both sides: - 2x ≥ 0

        Divide by - 2 (again, you must change the sign): x ≤ 0

Then, the solution set is:

  • x > 18 and x ≤ 0 and that is an empty set, since x cannot be at the same time greater than 18 and less or equal to 0.

This is, you conclude that the compound inequality is false, because there is not a value of x which is a solution.

Answer:

22 and 0

Step-by-step explanation:

−44 > −2x − 8 ≥ −8?

/-2    - 44  > -2x / .  -2      -8 ≥ -8

        = 22                              +8 =0
