Answer:
n ≤ 3 67/80
Step-by-step explanation:
The symbolic inequality here is 6n - 4 9/10 ≤ 18 1/8.
or 6n - 4.9 ≤ 18.125.
Adding 4.9 to both sides, we get 6n ≤ 23.025, or n ≤ 3.8375, or
n ≤ 3 67/80
Step-by-step explanation:
the perimeter =
4+4+6+4.5+2+4+4+2 =
30.5 cm
the area of:
• the bigger rectangle = 6×4 = 24 cm²
• the smaller triangle = 4×2 = 8cm²
• the triangle = ½×2×4 = 4cm²
the total area = 24+8+4 = 36cm²

Answer:
x=-42 to check ur answer place it like this 7-(-42) =49 which is correct
Let x be the page number then x+1 would be the other page number (because the pages are two facing pages which means they follow on consecutively)
Then
(x)(x+1) = 156
x^2 + x - 156 = 0
x = 12 or x = -13( but x can't be a negative number)
so x = 12
and the next page is 13
