Answer: N = 5
Step-by-step explanation:
M = 3N + 4R
M = 43
R = 7
Replacing by the values
43 = 3N + 4*7
43 = 3N + 28
43-28 = 3N
3N = 15
N = 15/3
N = 5
10/12= $.83 per inch
20/18= $1.11 per inch

Answer:
29
Step-by-step explanation:
Let w represent the number of wins. Then the number of losses is w-18. The total number of games played is ...
wins + losses = 40
w + (w-18) = 40
2w = 58
w = 29
The Rangers won 29 games.
(1) Repetition allowed : There are 4 choices for both positions, so 4 × 4 = 16 2-digit numbers can be formed. (2) Repetition not allowed : There are 4 options for tens position, and three options for ones position. Therefore, 4 × 3 = 12 2-digit numbers can be formed.
