<span>R = 11 - 2m
S = n + 5
T = -m - 3n + 8
R - S + T
(</span>11 - 2m) - (n + 5) + (-m - 3n + 8)
6 - 2m - n - m - 3n + 8
14 - 3m - 4n
-3m - 4n + 14
Martin will have to mark 0.125 on the
Let the original weight of the scale be 1kg. Hence we can say the original mark for 1kg weight is 1 that is:
1kg = 1 ................ 1
Since we are to calculate where to mark for a 1/8 kg weight, we can write;
1/8 kg = x ..................2
Divide both expressions
![\frac{1}{1/8}= \frac{1}{x}\\\\Cross \ multiply\\8= \frac{1}{x} \\x = \frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B1%2F8%7D%3D%20%5Cfrac%7B1%7D%7Bx%7D%5C%5C%5C%5CCross%20%5C%20multiply%5C%5C8%3D%20%5Cfrac%7B1%7D%7Bx%7D%20%5C%5Cx%20%3D%20%20%5Cfrac%7B1%7D%7B8%7D)
This means Martin will have to mark 0.125 on the scale.
