Answer:
32/9
Step-by-step explanation:
Translating the word problem into a symbolic equation yields:
3n - 3 = 5/6
Solve this for the number (n):
Multiplying both sides of this equation by 6 clears out the fraction term:
18n - 18 = 5
Adding 18 to both sides isolates 18n: 18n = 23
Then the number is n = 23/18, and:
one more than twice this number n is 2(23/18) + 1, or:
46/18 + 18/18, or 64/18, or (reducing this result)
32/9
Answer: a=2 b= 11/6 or 1 5/6
Step-by-step explanation:
Use pythagoras.
sqrt((6--12)^2 + (8--4)^2) = 6*sqrt(13) = 21.63 (2 d.p.)
