Pls help meeee asap!!!!

Answer:

Step-by-step explanation:

Let the points scores by Denny = x

Point score by Keshawn  = 3 * x = 3x

Total score = 280

x + 3x = 280

   4x   = 280     {Divide both sides by 4}

4x/4  = 280/4

     x = 70

3x = 3*70 = 210

Point scored by Keshawn = 210

If Denny's point total is 70, Keshawn's point is 210

Answer:

Step-by-step explanation:

1. 5+9(1+4n)=-30

-5               -5

--------------------

9 (1 + 4n) = -35

/9                /9

----------------------

(1 + 4n) = -35/9

1 + 4n = -35/9

-1            -1

------------------------

4n = -44/9

/4        /4

-----------------------

n = -11/9

2. 6(3-8c)=-31

   /6            /6

---------------------

(3 - 8c) = -31/6

3 - 8c = -31/6

-3          -3

---------------------

-8c = -49/6

/-8      /-8

-----------------------

c = 49/48

3. -21=8+9(f-3)

8 + 9 (f - 3) = -21           we switched sides here

-8                  -8

------------------------

9 (f - 3) = - 29

/9              /9

-------------------------

f - 3 = -29/9

 +3        +3

--------------------------

f = -2/9

4. 9k-7-5=-25

9k - 12 = -25

    +12     +12

--------------------

9k = -13

/9      /9

--------------------

k = -13/9

5. 8(3y-6)=-25

   /8            /8

------------------------

(3y-6) = -25/8

3y - 6 = -25/8

    +6        +6

-----------------------

3y = 23/8

/3      /3

-----------------------

y = 23/24

6. 16=-5(2b-7)

-5(2b-7) = 16            we switched sides here

/-5             /-5

--------------------

(2b-7) = -16/5

2b - 7 = -16/5

     +7     +7

--------------------

2b = 19/5

/2      /2

---------------------

b = 19/10

The maximum number of feet of cable that can be run is 300 feet.

An equation is an expression that is used to show the relationship between two or more variables and numbers.

Given a loss rate of 5 dB per 100 ft. Hence for a loss of less than 15dB:

Maximum length of cable = 15 dB / ( 5 dB per 100 ft.) = 300 feet.

The maximum number of feet of cable that can be run is 300 feet.

8k - 9(4k + 4) = 8k - 36k - 36 = -28k - 36

Let's rewrite in the simplest term,

→ 8k - 9(4k + 4)

→ 8k - 36k - 36

→ [-28k - 36]

The simplest term is -28k - 36.
