Answer:

Step-by-step explanation:
Try to say it and then write it out. I hope this helps.
I think A is 145m...
200m+ (-55m) since the submarine is under water it will be negative which ends up to be 145m
The answer is 2/3 times as heavy as the dog.
Since we are looking for the weight of the cat in relation to the dog's weight, we have to divide the cat's weight by the dog's weight.
5 1/2 = 5.5, 8 1/4 = 8.25.
5.5 / 8.25 = 2/3.
The slope should be m= -9/11
4500 + 1.20x < 4.80x
4500 < 4.80x - 1.20x
4500 < 3.60x
4500/3.60 < x
1250 < x.......minimum number would be 1251
