Answer:
Combing like terms we get 13x + 48x = 61x and -19y + 43y = 24y so the answer is 61x + 24y.
Answer: The mass of solid a is 4800 grams
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
For solid b = 40.32 cm2 / 6912 grams
For solid a = 28 cm2 / x grams
Where x is the mass of solid a.
So:
40.32 / 6912 = 28 / x
x = 28 / (40.32 / 6912)
x = 4800 grams
The mass of a is 4800 grams
