Answer:
The order of operations is PEMDAS
First step is to do everything is parenthesis or brackets
5+{2*[(5-1)+6]}/4
{2*[(5-1)+6]}
First you would go 5-1=4, because that is the first equation that is in parenthesis by itself.
{2*[4+6]}
Next you would go 4+6=10, because that is your next smallest bracket
{2*10}
Last you would go 2*10=20
Your equation now looks like this
5+{20}/4
In PEMDAS your next step is exponents, but we don't have any so we go on to the next one which is multiply/division
5+5
You would go 20/4=5
Last step is to add/subtract
5+5=10
Your final answer would be 10
Hope this helps ;)

Answer:
The solution of given problem is k = 11
Step-by-step explanation:
<u>slope of given two points formula:-</u>
slope m =
.....(1)
Given points are (1,3) and (5,k)
given slope m = 2
now substituting m =2 and the given points are (1,3) and (5,k)

on simplification we get solution
