<u>Answer: </u>

The correct answer option is: If a = b and b = c, then a = c.  

<u>Step-by-step explanation: </u>

The Transitive Property of Equality states that if one value, lets say a is equal to another value, call it b, which is equal to another value, call it c, then the very first value a would be equal to the third value c.

So from the given answer options, the correct option is: If a = b and b = c, then a = c.

Answer: If a=b and b=c, then a=c

Step-by-step explanation:

Let be "a", "b", and "c" all real numbers, the Transitive property of equalities states that :

If a=b and b=c, then a=c

You can observe that if two numbers are equal to the same number, then all this numbers are equal to each other.

For example, applying the Transitive property of equalities to:

x+3=5 and 2x+1=5

You can equate them:

x+3=2x+1

And solve for "x":

3-1=2x-x\\\\x=2

16. Peter works part time for 3 hours every day and Cindy works part time for 2 hours every day.
Ber [7]

Answer:

Part A)

  • 4.50 × 3 > 4.50 × 2
  • 13.5 0 > 9

Part B)

  • r ≥ 7

Explanation:

1) The earnings are calculated multiplying the number of hours by the hourly rate.

2) The hourly rate of both Peter and Cindy is the same: $ 4.50 / hour

3) Let the variable used for computing the number of hours be h.

4) The number of hours Peter works every day is 3 hours, so, using the letter P to name Peter's earnings, the expression to calculate his earnings is:

  • P = 4.50 × 3

5) Similarly, the expression to calculate Cindy's earnings would be:

  • C = 4.50 × 2

<u>Answering part A)</u>

<u>Y</u>ou have to write an inequality to compare Peter's and Cindy's earnings:

  • 4.50 × 3 > 4.50 × 2
  • 13.5 0 > 9

This is, the earnings of Peter are greater than the earnings of Cindy.

<u>Part B)</u>,

You have to write an inequality to calculate Cindy's per-hour income so that she earns at least $ 14 a day.

  • Here, C ≥ 14, because the sign ≥ means greater than or equal to, meaning the the earnings are greater than or equal to 14.

  • Thus, since she works 2 hours per day, the inequality becomes 2 × r ≥ $ 14, where r is the per-hour income.

  • To solve it follow these steps:

Given: 2r ≥ 14

Divide both sides by 2: r ≥ 14 / 2

Simplify: r ≥ 7

That means that Cindy's per-hour income should be at least $7 and hour so that she earns $14 a day.

Answer:

\frac{-47}{6} = 7.833

Step-by-step explanation:

Expression given is:

-4\frac{2}{3} -(3\frac{1}{6})

Now change the mixed fraction to improper fractions;

-\frac{14}{3} -\frac{19}{6}

Now take a common denominator:

-\frac{28}{6} -\frac{19}{6}

Now we can simplify the the above equation:

\frac{-28-19}{6}

\frac{-47}{6} = 7.833
