Add up all the lengths of the segments. kb = bl, ak = cl, am = cm.
the perimeter is 48
-2y-(-8y-2) = -2y + 8y + 2 = 6y + 2
2(3x + 16) - 7x = 6x + 32 - 7x = -1x + 32 = 32 - x
-x + 6 + (-3) + x + (-4) = -x + 6 - 3 + x - 4 = 3 - 4 = -1
$63.99 *0.85=$54.40 ($54.3915)<span> rounded = Sale Price
$63.99-54.40= </span> $9.60 $9.59 rounded = Discount
Let the number of History books be x. Then:-
x + x - 59 = 343
2x = 402
x = 201
So there are 201 History books and (201 - 59) = 142 Chemistry books.
