Okay. so I'm gonna assume you know what factor out means--were gonna take out 5/6. what we need to know is, how does that affect our ending number 2/3? well, we're gonna have 5/6 times some stuff first off, right?
5/6 ( )
so what's in the parenthesis? well, if we distribute in our mind, S would just have to be by itself for it to work out. so we have
5/6 ( s )
but what about 2/3? well, if we're multiplying everything on the inside by 5/6, how can be get it to cancel and leave 2/3 alone? we could divide 2/3 by 5/6, right?
5/6 ( s + (2/3) / (5/6) )
now, when we distribute our 5/6, we'll have just 2/3 at the end. now let's simplify that end term so it looks a little better. if we divide by a fracion, that's the same as multiplying by the flipped version, so let's do that.
2/3 / 5/6 = 2/3 × 6/5 = 2 (6) / 5 (3) = 12/15
we can reduce 12/15 by dividing the top and bottom by three.
= 4/5
so our final answer would be:
5/6 [S + 4/5] you can redistribute to make sure it matches. Anyway, hope that helps!
Answer:
Step-by-step explanation:
let workers=n
time=t(weeks)
t=k/n ,where k is constant .
when t=8,n=3
8=k/3
k=24
t=24/n
n 2 4 6 12
t 12 6 4 2
Answer:
8 cm and 9 cm
Step-by-step explanation:
The other two sides added together have to equal a larger number than 13, since 13 is the largest side.
5 + 8 = 13
6 + 7 = 13
7 + 2 = 9
8 + 9 = 17
2/7 ≈ 0.2857
To determine percentage, move decimal 2 places to the right. ≈ 28.57%
