Answer:
x=.3
Step-by-step explanation:
3(x-2)=3x -2
(1x-2)=3(-1x)=3x -2
3(-1x)=3x -2
+3x +3x
3*2x=2
6x=2
6x/6=2/6
x=.3
Answer:
16 runner
Step-by-step explanation:
It is given that,
Each group will need to run a race that is 1/2 of a mile long. Each runner has to run 1/8 of a mile in the race.
Let there are x no of runners. ATQ,

So, there are 16 runner that are needed for each relay race group.
I believe it’s 70 because a straight like always adds up to 180 so 180-110=70
Find

where

<span>So to find the left sided limit, you need to plug in -8, into x+9
and to find the right sided limit, you need to plug in -8, into -7-x.
</span>
<span>If the two sides of the limit are no equivalent, then </span>

Since both sides are equal to 1, the limit is 1.
