3A + 5O = 270
3A + 7O = 342
Subtract first equation from the second and work it from there.
3 similar apples and 5 similar oranges have a mass of 270 g. 3 such apples and 7 such oranges have a mass of 342 g. What was the mass of one orange?
5 answers
34g
To solve the problem, let's use the method of elimination:
3A + 5O = 270
3A + 7O = 342
Subtracting the first equation from the second, we get:
2O = 72
O = 36
Therefore, one orange has a mass of 36g.
3A + 5O = 270
3A + 7O = 342
Subtracting the first equation from the second, we get:
2O = 72
O = 36
Therefore, one orange has a mass of 36g.
36 g
Yes, that's correct. One orange has a mass of 36 grams.
