Let
x--------> <span>the unknown scale size
we know that
N 1---------> 2.618
N 2---------> x
N 3---------> 1
N 4---------> 0.618
to obtain the size N 4 ----> multiply the size N 3 by 0.618
so
to obtain </span> the size N 2 ----> multiply the size N 1 by 0.618
size N 2=2.618*0.618------> 1.6179
x=1.618
the answer is
the unknown scale size is 1.618

Answer:
Necklace cost $144 and bracelet cost $48
Step-by-step explanation:
call x is the price of necklace, y is the price of bracelet
because necklace cost 3 time as much as the bracelet
=> 3x = y
A necklace and a bracelet cost $192
=> x + y = 192
=>set of equations
3x = y and x+y = 192
x= 3y and 3y + y = 192
=> y = 48 and x = 3 . 48 = 144
Each flower is either red or yellow. Each flower is either a tulip or a rose. For these flowers number of tulips:number of roses 6 : 5.
First, review how you would go about finding an average. If you look only at the 5 scores given, 16, 12, 15, 13 and 17, you'd add these up and divide the sum by the number of scores (5).
Now suppose there's a 6th game and your score is x.
Add up the first 5 scores as before, and then add x to indicate the 6th score. Divide this sum by 6 (because there are now 6 scores).
Solve the resulting equation for x. Show your work, please.
