Jessica, Chau, and Kareem sent a total of 84 text messages during the weekend. Kareem sent 4 times as many messages as Chau. Jes
swat32

Answer:

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9

Step-by-step explanation:

Let number of messages sent by Chau = c

Number of messages sent by Kareem = 4 times as Chau

                                                                = 4 * c = 4c

Number of messages sent by Jessica = 6 fewer messages than Chau

                                                               = c - 6

Total messages = 84

<u>c + 4c + c</u> - 6 = 84                {Combine like terms}

<u>6c</u> - 6 = 84         {Add 6 to both sides}

6c  = 84 + 6

6c = 90   {Divide both sides by 6}

c = 90/6

c = 15

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9

Factor 1/3 out of 1/3p-2/3 please answer this! Easy 20 points!
Tju [1.3M]

Answer:

\frac{1}{3} (\frac{1}{p} - 2)

Step-by-step explanation:

Given the equation = \frac{1}{3p} - \frac{2}{3}

Required: To factor out 1/3;

\frac{1}{3p} - \frac{2}{3}

1/3 is common to both sides;

So, 1/3 is a common factor

\frac{1}{3} (\frac{1}{p} - 2)

To solve for the value of p;

\frac{1}{3} (\frac{1}{p} - 2) = 0

\frac{1}{p} - 2 = 0

\frac{1}{p} = 2

1 = 2p

p = \frac{1}{2}

PLEASE HELP!! ITS A TEST!!
irakobra [83]

Answer:

40°

Step-by-step explanation:

A parallelogram is a quadrilateral (a four-sided object) with parallel sides

Some of the characteristics of a parallelogram includes:

1. Opposite sides and angles are congruent.

2. Opposite angels are congruent  

3. Consecutive angles are supplementary  

4. The diagonals bisect each other

Angle DBC = ABD = 35 (alternate angles are equal)

Angle ADB = 180 - 35 - 105 = 40

I subtracted from 180 because sum of angles in a triangle is equal to 180

I need all the answers please help me and show me step by step...please...

1. No. This is because the system does not go up equally every time. There is no common difference

2. Yes. The common difference is 12 and it goes up by that much every single number.

3. The common difference is <u>3</u>. This is because they all have a common difference and it increases by 3.

4. The common difference is -<u>6</u>. This is because every time the number goes down, it has a common difference of -6. The distance from each ascending or descending number in this pattern is 6, but it descends by default, so it would be negative.

5. The common difference is -<u>10</u>, and the next three terms are <u>-20</u>, <u>-30</u>, and <u>-40</u>. The common difference is -10 because the distance from each ascending or descending number is 10, but it descends by itself versus ascending, making the difference negative. The last three numbers are -20, -30, and -40 because you subtract 10 each time.

6. The common difference is 2 and the last 3 numbers are 92, 90, and 88. I think you get how this goes now.

7. Recursive formula: a1=a2-5 .Explicit formula: <em>f</em>(<em>n</em>)=12-5(<em>n</em>-1) 20th term: -83: I seriously do not want to have to explain this. The recursive formula shows term 1 is equal to term 2 plus the common difference. The explicit formula shows the first term, the common difference, and one less than the number term. The 20th term is me just taking away 5 over and over and over again.

8. recursive formula: a1=a2+3 . Explicit formula: f(n)=1+3(n-1) 32nd term: 94

This was really hard to explain. The recursive formula shows term 1 is equal to term 2 plus the common difference. The explicit formula shows the first term, the common difference, and one less than the number term. The 32nd term is me just adding 3 over and over and over again.
