Answer:
Step-by-step explanation:
487 is a prime, because 487 is only divided by 1 or by itself
I think the answer is 4/12 or 1/3
7x +16 < -5(4 - 5x)....given
7x + 16 < -20 + 25x....distributive property
16 < -20 + 18x ... subtraction property
16 + 20 < 18x.....addition property
36 < 18x
36/18 < x.....division property
2 < x
4/10 = 12/20 since 4/10 = 10/20
