(4-5x)+43=3-32(-82) please answer!!

Mathematics
1 answer:
kotykmax [81]3 years ago
7 0

Answer:

x = -516

Step-by-step explanation:

(4 - 5x) + 43 = 3 - 32(-82)    {Multiply 32 and (-82)}

4 - 5x + 43 = 3  - (-2624)  

4 - 5x + 43 = 3 + 2624   {add 4 and 43 in LHS}

   -5x  + 47 = 2627      {Subtract 47 from both sides}

     -5x        = 2627 - 47

          -5x   = 2580         {Divide both sides by (-5)}

                x = 2580/(-5)

x = -516

Suppose you know the perimeter of n octagons arranged as shown. What would you do to find the perimeter if 1 more octagon was ad
kogti [31]

As shown in the figures given :

For Figure 1 : perimeter = 8 units   [As can be seen in the figure]

For figure 2(with 2 octagons) : perimeter = 8 × 2 - 1 = 15 units    [since 1 side is common ]

For figure 2(with 3 octagons) : perimeter = 8 × 3 - 2 = 22 units  [since 2 sides is common ]

If one more octagon is added

then perimeter = 8 × 4 - 3 = 29 units    [since 3 sides will be common ]

Sergio039 [100]

Answer:

D2 = 24

Step-by-step explanation:

given is a data set as

24, 64, 25, 40, 45, 34, 14, 26, 28, 24, 58, 51

We have to find the second decile for the above

Arranging in ascending order we get

14, 24, 24, 25,26,28, 34, 40, 45, 51, 58, 64

2nd decile is equal to 20th percentile

20th percentile formula entry appearing which sorts 20% below and 80% above.

i.e. (20%*(14+1)) = 3rd entry

Thus 20th percentile is24.

D2 = 24
