An equivalent expression is 280/290, but there are many possible answers
(-9a - 20c) - (-15a + 3c) - (-22a - 7c)
= -9a - 20c + 15a - 3c + 22a + 7c
= (-9a + 15a + 22a) + (-20c - 3c + 7c)
= 28a - 16c
Answer:
(x + 10)(x - 7)
Step-by-step explanation:
It is 3 and 10 in some order. The difference is 7 and it is plus, so the larger number is +10 and the smaller one - 3
(x + 10)(x - 3) should be the answer
10x - 3x = 7x
1 kg is equal to 1,000 g. So, in order to convert, you need to multiply 20x1,000. To get 20,000 g.
