<u><em>Answer:</em></u>
- 84x - 70
<em><u>Step-by-step explanation:</u></em>
We want to combine like terms:
-10 - 90x + 6x - 60
We can see (-10) and (-60) are both regular constants so:
- 10 - 60 = - 70
Then (-90x) and (+ 6x):
6x - 90x = - 84x
- 84x - 70
Answer:
it will take her 40 seconds to finish the race.
3/8 per minute, would make it 1/8 every 20 seconds. since she only has 2/8 of a mile left to go, 20 seconds +20 seconds = 40 seconds
(if you needed how long it takes her to run the whole race, it's 2 minutes 40 seconds, which would make her the fastest mile runner in the world)

I hope this helps :)
(x + 9)(x + 12) = 0
Expanding the brackets, we get:
Answer:
148

Answer:
Step-by-step explanation:
Let first group of people take x candies each
and second group of people take y candies each
5x + 7y will be total candies
5x +7y = 239 (needed to find positive solution of x,y)
now take x=38, y =7
or x=31, y= 12
hence lots of possibilities ,so we can not say exactly
