What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Main body:
200-meter race finished by Thomas = 25.7 sec
200-meter race finished by Mikah = 28.1 sec
The difference between their time shows How much faster did Thomas run the race than Mikah.
=28.1 - 25.7
=2.4 seconds
Hence, Thomas finished 2.4 seconds faster than Mikah which has higher speed than Mikah.

Answer:
k = 3 1/5
Step-by-step explanation:
We want to isolate k, or move all numbers to the other side.
1/2 (4 - k) = 2/5
(4 - k) = 2/5 * 2
-k = 4/5 - 4
k = 4 - 4/5
k = 3 1/5
Doubles are adding the same number together, as with 5+5=10.
With doubles +1, the numbers must be in beside each other in counting order going up or down (ex: 4, 5, 6 and 9, 8, 7). Do the SMALLEST number, double it, then add one. So, 9+8 would be 8+8=16, +1=17. You must know your doubles facts before this strategy is useful.
