Measure angle JKC + measure angle CKL = measure angle JKL
measure angle JKL = 122 and measure angle CKL = 74
Substitute wuth these values in the equation to get measure angle JKC where:
JKC + 74 = 122
measure angle JKC = 122 - 74
Answer:
unit rate is similar to speed / velocity:
[<em>unit</em><em> </em><em>rate</em><em> </em><em>must</em><em> </em><em>have</em><em> </em><em>units</em><em> </em><em>including</em><em> </em><em>per</em><em> </em><em><</em><em>time</em><em>></em><em> </em>]
1st step is to simplify the denominator in other words you need to factor the denominator
the GCF would be 3x
we would have
3x/3x(3x - 1)
the answer would be
1/3x-1
Since we need to find the number of ways they could enter first, second and third place, (I can't demonstrate, but you should get the idea) take 8, 7 and 6 and multiply them, 5-1 we don't need, we just need 8, 7, and 6, multiply those three numbers and you get 336, there you go, 336 ways to organize all 8 girls in first, second and third place, hope this helps
