171 pennies, or a dollar and 71 cents.
133 divided by seven is 19, (that's one-seventh right there) so multiply 19 by two to get 38, then add that to 133 (your "one")
If he has 12 nails left, he used 36 nails.
2x ≤ 30
You must isolate x. To do this divide 2 to both sides
2x/2 ≤ 30/2
x ≤ 15
x is less then or equal to 15
Hope this helped!

Answer:
#2 is a ratio so you gotta add.
#3 it’s just adding it for example 2p + 5a = 7pa
Since the common difference is 6, we can assume that the sequence is arithmetic, with rule
T(n)=6n+5 where T(1)=11
T(9)=6(9)+5=59
