Answer:
y = 6/11 x + 13/11
Step-by-step explanation:
x:14 = 7:8
x:14 = x/14
7:8 = 7/8
x/14 = 7/8
Multiply the numerator of the 1st ratio with the denominator of the 2nd.
And multiply the numerator of the 2nd ratio with the denominator of the 1st.
Doing so, we get -
x * 8 = 7 * 14
So, 8x = 7 * 14
8x = 98
We divide 98 by 8 (transposition method)
x = 98/8
Therefore, x = 12.25
The objective here is to find
(so called common ratio):
So assuming the first element of sequence is 3 (as you mentioned) we now can define the recursive rule for this geometric sequence:
Answer:
It will became like this.
- 38.5kg.
- 77.kg
- 192.5.kg
Hope this will help you.
