For
|a|<b
assume
-b<a<b
so
add 5 to both side
|-2-8x|<66
assume
-66<-2-8x<66
add 2 to both sides
-64<-8x<68
divide everyboy by -8, don't forget to flip sign
8>x>-8.5
-8.5<x<8
the solution is all numbers between -8.5 and 8, not including -8.5 and 8
in interval notation: (-8.5,8)
or
S={x|-8.5<x<8}
Answer:
4/36
Explanation:
There are 6 numbers and if spines twice other 6, if these are multiplied with each other there will be a total of 36 products or probabilities.
On total there are four 12
2 x 6
3 x 4
4 x 3
6 x 2
Answer: 4
Step-by-step explanation: Since the total number of games played in the graph is 12, if you half that and get six, you half the total number of wins as well and get 4. :]
Divide 1/2 by 1/8 by doing Keep change flip. 1/2 divided by 1/8 turns to 1/2 x 8/1 =9/2 and then divide 9/2 like this 9 divided by 2= 2 1/2
Answer:
6/7 ÷ 3/14
= 6/7 × 14/3
= 2/7 × 14 (we cancelled 3 with 6)
= 2×2 (we cancelled 7 with 14)
= 4
