Answer:
1=0 2
Step-by-step explanation:
190 runners would not have finished the race.
If you add up all the waves, there were 952 total runners.
If 7/8 finished the race, then that means that 1/8 did not finish the race.
Just multiply 1/8 by 952 to get the amount that did not finish.
It would be 190.
Answer:
d=1
Step-by-step explanation:
Factor d^2 - 2d - 8 into (d-4)(d+2)
Move -2/d+2 onto the other side, changing it into 2/d+2.
Let the empty side equal zero.
Add 3/d-4 and 2/d+2
Then add that to -3d.
Multiply 0 by d+2 and d-4 to get 2d-2 by itself.
2d=2
d=1
I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
