Simplify.

16.3 – (–4.2) + 15.9

Answers

The answer is 36.4.

16.3 - (-4.2) = 20.5 because a two subtraction sign will cancel out and become positive.
So 20.5 + 15.9 = 36.4

Use the Distributive Property and simplify the expression.9 + 4(2x – 1) + 8

I got 9?

Answers

The distributive property: a(b - c) = ab - ac

9 + 4(2x - 1) + 8 = 9 + 4·2x - 4·1 + 8 = 9 + 8x - 4 + 8 = 8x +13
9 + 4 (2x - 1) + 8
Expand the bracket

=>  9 + (4 * 2x) + (4 * -1) + 8
       simplify the bracket
   
      9 + 8x - 4 + 8
      make the expression equal to 0 and solve
 
       9 + 8x - 4 + 8 = 0
       9 - 4 + 8 + 8x = 0
       13 + 8x = 0
 
       8x = -13

         x = (- 13)/(8)

Finish the sequence 1,1,1,3,5,9,17,31,57, , ,

Answers

Your basically adding the first 3 numbers to get the next for example: 1,1,1=3
and then 1,1,3,=5 and then 1,3,5=9 then 3,5,9 =17 so on and so forth.

so to get the first answer of 105 I added the last 3 numbers in the sequence together (17,31,57) to get 105

the next 3 numbers in the sequence are:
105,193,355
