Answer:
additive inverse of
Step-by-step explanation:
Additive inverse of any number is that number added to the given number result into zero. For example a is an additive inverse of -a because a+(-a) = a-a = 0
According to the question, -4 and 4 are additive inverse of each other. Hence -4 is the additive inverse of 4
So if you need 1/2 cup for a 3-layer, then it means that you need a third of that for a one-layer. you need to divide 1/2 by 3. It is easier to get that if you use another form of 1/2, for example 3/6. In this case you simply divide this by 3 and you'll get 1/6.
15. The left triangle is similar to the whole triangle. The x of the small triangle is proportional to the hypotenuse of the large triangle (9+16 =25). the x of the large triangle is proportional to the 9 unit leg of the small triangle. this creates the proportion

. Cross multiply to get

take the square roots of both sides to get x=225
Soil is not a Basic need of all the organisms.
All we have to do is add 1.5 GB per day times the 8 days that's already happened to the current 6 GB, and so it looks like this:
8(1.5)+6
