<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
The least possible value of 8x - 13 when 9 is less than or equal to 3/4 + x is;
53.

Answer:
B
Step-by-step explanation:
If 12 pencils are 1.25, 24 would be 2 x 1.25. And 4 notebooks worth 0.65 would be 4 x 0.65
Added up, this expression is:
(2 x 1.25) + (4 x 0.64)
To find perimeter you add up all the sides so 5cm+6cm+17cm+8cm. This will get you 36cm.
