9/2”
15 strips means 14 cuts so that’s 14/8” lost
14/8 + 11/4 (or 22/8) = 36/8 = 9/2”
The answer: 9 and 10 or 8 and 9
8x8=64
9x9=81
10x10=100
They are close by 18 so If it’s only an answer I would go for 8 and 9
3x - 6y = 20
-6y = -3x + 20
y = 1/2x - 20/6.....slope = 1/2...y int = -20/6 = -10/3
2x - 4y = 3
-4y = -2x + 3
y = 1/2x - 3/4..slope = 1/2...y int = -3/4
same slope, different y int = parallel lines = no solution = inconsistent
Answer:
2x+2x is 4 +3x is 12+ 1 is 13 + 3 is 15 - 2 is 13 -1 is 12
so x=15
and y=12
