Answer: Metal A is 3 times faster than Metal B.
Step-by-step explanation:
Since we have given that
Time taken to oxidised metal A = 
Time taken to oxidised metal B =
seconds
So, ratio of metal A to metal B would be

So, Ratio of Metal A to Metal B is 1 : 3.
Hence, Metal A is 3 times faster than Metal B.
You could do 600+100=700 because it would be close to the actual rusult
Answer:
You would first put it into point slope form which is (y-y_1)=m(x-x_1). Then you would solve for y.
Answer:
one solution.............
Answer: 5
Step-by-step explanation: The first piece of information that you need to know is that the product is the answer when two numbers are multiplied. Therefore, you need to multiply the two sets of numbers, and then subtract.
The formula will be:
(5 x 2) - (5 x 1)=
First, do what is inside the parentheses:
10 - 5=
And solve...
