Answer:
44
Step-by-step explanation:
0.5 m - 0.75 n = 16
Substitute n = 8 into the equation
0.5 m - ( 0.75 × 8 ) = 16
0.5 m - 6 = 16
( Add 6 to both sides )
0.5 m = 26
( Divide by 0.5 )
m = 52
1st rock = 19.28 grams
2nd rock = 25.30 grams
3rd rock = 46.3 grams
Add 1st and 2nd rock to get the combined mass
19.28 + 25.30 = 44.58 combined mass of 1st and 2nd rock
Subtract:
3rd rock mass - combined mass of 1st and 2nd rock
46.30 - 44.58 = 1.72 grams
1.72 grams greater was the mass of the 3rd rock than the combined mass of the two rocks.
2/3 chance you pull red on the first pull because there are 50 red to the 25 black marble
