It's 20. I was looking at multiple questions at the same time :D
So
16 + 9(n-1) = 7 + 9n
and
-4 + (-7)(n-1) = 3 - 7n
Is that Correct?
difference: 9 First Term: 61 Arithmetic Sequence
difference: 7 First Term: -39
Answer: 9
Answer: 7
thx
omg thank u so much
200
23!
This is a ratio so 2:5
2 + 5 = 7
How many 7s go into 161?
oh ok so the second one but there are two d so d2
Would it be
5d2 - 5d3d
or
10d - 15d
???
That is so true.
what do u mean?
ok thx for the help
3 x 2 = 6s
3 x 4 = 12t
So 6s - 12t
is that right?
Omg it's so easy now
ohhhhhhh ok i get it now thx
