Answer:
0.865 
Step-by-step explanation:
Specific gravity is a ratio of the weight of a substance to the weight of an equal volume of a substance chosen as a standard. The standard for liquid and solids is water while for gas is hydrogen.
Amount of displaced oil = 12.64 g — 9.12 g = 3.52 g 
Amount of displaced water = 12.64 g — 8.57 g = 4.07 g 
Specific gravity of oil = 3.52 g / 4.07 g = 0.865

Since 6x - 44 and 88 degrees are the same (exterior angles), we can start off with the first equation, 6x - 44 = 88
6x - 44 = 88
     +44    +44
6x      =   132
÷6         ÷6
x  = 22
same with the second problem (exterior angles are equal):
equation:
15x + 6 = 9x + 54
        -6              -6
15x    = 9x + 48
-9x      -9x
6x   =    48
÷6         ÷6
x   =   8
Hope this helped! :D
