Alarge emerald with a mass of 378.24 grams was recently discovered in a mine. if the density of the emerald is 2.76grams over centimeters cubed, what is the volume? round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
