Answer:
C
Step-by-step explanation:
To get 63/80 converted to decimal, you simply divide 63 by 80. Don't worry. You don't need to get the calculator out, because I did this for you.
63/80 as a decimal is:
<span>0.787500</span>
Start by distributing the 6 through the parenthses on the left side.
So we have 6x + 24 = 30.
Solving from here, I would subtract 24 from both sides to get 6x = 6.
Finally, dividing both sides of the equation by 6, we have x = 1.
Answer:

Step-by-step explanation:
Surface area of this shape = area of 2 triangles + area of 3 rectangles

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}
