15 boys and 16 girls....total is (15 + 16) = 31
probability that a boys name is drawn : boys/total ppl = 15/31
In fact, the least common multiple is 819. Glad to help. :)
Answer:
x = 30
Step-by-step explanation:
Since this is a right triangle,
90 = (x + 20) + (x + 10)
90 = x + x + 20 + 10
90 = 2x + 30
90 - 30 = 2x
60 = 2x
60/2 = 2x/2
30 = x
Check:
x + 20
30 + 20 = 50
x + 10
30 + 10 = 40
50 + 40 = 90
Hope this helps!
