Answer:
3x-1=16*2
3x=32+1
3x=33/:3
x=11
Step-by-step explanation:
Answer:
0.7
Step-by-step explanation:
It would be rounded down to 244 as its only .1 so its closer to 244 than it is to 245
1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price
Answer:
Step-by-step explanation:
I don’t know why they bother teaching recursive formulas as the explicit is almost always used :)
For 2,9,16,23...
Recursive is a(n+1)=an+7
Explicit is an=2+7(n-1)
(or more neatly an=7n-5)
For 2,14,98,686...
Recursive is a(n+1)=7an
Explicit is an=2(7^(n-1))
(or (2/7)7^n )
