I’m like ligiterally freaking out rn

-0.5 kg
Step by step explanation:
the negative value means that the cats weight decreased from the previous months and the positive values means that the cats weight increased

we’re trying to find how much change the car went through in the last 3 months

so we just add up the changes
-0.7+0.5-0.3=-0.5

This tells us that in 3 months the cats total weight change is a decrease of 0.5 ponds therefore the answer is -0.5

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
