S=3/5, because if we multiply 3 on both sides (to isolate the s), then 1/5 times 3 is 3/5 (and 1/3 times 3 is 1)
This is Additive Property of Zero.You are adding zero and nothing changes.
This becomes a very useful tool later on in math. Say you want to "complete the square"; you have to abuse the Additive Property of Zero to do so. By using this Additive Property of Zero with varialbes, you do not change the original exprssion.
Since negative 1 is negative, we multiply by 1 and make it negative. Therefore, if the integer is x, the product of that and negative 1 is -1*x=-x
Answer:
so the answer is B
Step-by-step explanation:
W = 6a +3b - 4
w - 3b + 4 = 6a
a = w - 3b + 4 divided by 6
