Answer: x = 10.6666666 or 10 2/3
Step-by-step explanation:
6x + 8 = 72
- 8 -8
6x = 64
6x/6 = 64/6
x = 10.6666666 aka 10 2/3
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:
23
Step-by-step explanation:
25-14 = 11
11+12=23
that would be your answer
Answer:
Step-by-step explanation:
h^2=x^2+y^2, here x and y are equal so we can say
h^2=2x^2, we see that h=2(2^(1/2)) so
2x^2=8
x^2=4
x=2
