Scientific notatino is
(number that is greater than or equal to 1 and less than 10) times (10^x)

so
318.9
we need to make it less than 10
move decimal 2 places to left
3.189

to make it the same number, we multipl it by 10^2 to make it go back

scientific is
3.189 times 10^2

Students planted 4(2x+3y) amount of trees on saturday and then 3(5x+4) amount of trees on Sunday. What is the total amount of tr

algol [13]

We have to add the amounts:

4(2x+3y) + 3(5x+4)

First, though, we have to distribute:

4*2x + 4*3y + 3*5x + 3*4
8x + 12y + 15x + 12

Now we just need to simplify:

23x + 12y + 12

The students planted 23x + 12y + 12 trees total.

PLEASE HELP!!!!! Write the absolute value inequality in the form

Elena-2011 [213]

Answer:

|x - 1 |> 6,

Step-by-step explanation:

First we find the distance between the two points

-5 to 7

7 - -5 =7+5 = 12

We find 1/2 that distance

12/2 = 6

So we are looking for a greater-than inequality because we are looking for the outsides because we want a less than and a greater than

|x - b |> c,

The center is 6 to that is c

|x - b |> 6,

To find the value of b

Let x = 7

7 -b =6

b=1

|x - 1 |> 6,

We can check by using -5

|-5 - 1 |> 6,
