Gomez found the masses of three rocks for science project .the first rock had a mess of 19.28 grams, the second rock had a mass of 25.3, and the third rock had a mass of 46.3. How much greater was the mass of the third rock than the combined mass of the other two rocks?

Respuesta :

Belfium
The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58

Difference between rock 3 and combined rocks 
= 46.3 - 44.58
= 1.72 grams

therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.
