Step-by-step explanation:Amos tbrewer1205
Step-by-step explanation:
a) unsuitable - the precision should have been about 0.030 kg (about an ounce)
b) unsuitable - the stopwatch should have a precision of 0.001 s
c) just about right, although I wouldn't mind it if its precision is of 0.05 mm
d) unsuitable - color matching requires much finer control so I would go with 1/8 cup precision.
Step-by-step explanation:
2A + B = 17
3A - B = 18
5A = 35, A = 7, B = 3
Hence the numbers are 7 and 3.
You are correct the answer is a:18
