Answer:
12.5 inches of gold chain.
Step-by-step explanation:
To get the remaining chain of gold we need to calculate
8/8 - 3/8 = 5/8 of 20 inches
then multiply:
20 * 5/8 = 100/8
100/8 = 12.5 inches
Answer:
11.2
Step-by-step explanation:
divide 160 by 14.3
Answer:
(L-a)/d + 1 = n
Step-by-step explanation:
Let's isolate (n-1), and after that isolate n:
1) subtract a from both sides: L - a = (n-1)d
2) Divide both sides by d: (L-a)/d = n-1
3) Add 1 to both sides, to isolate n: (L-a)/d + 1 = n
