Kong took 15 percent fewer seconds than nolan took to complete his multiplication timed test. kong took 858585 seconds.
how many seconds did nolan take?

100 seconds

Step-by-step explanation:

I've seen this question before. I know you didn't mean to put 858585.

The real question is "Kong took 15% percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 85 seconds. How many seconds did Nolan take?"

Now let's work!

Kong took 15% fewer seconds than Nolan took.

So Kong took 100%−15%=85%

Whatever Nolan's total was, Kong had 85% of that.

We know Kong took 85 seconds. 85% of Nolan's total is 85 seconds.

=100 seconds. 85%=15 seconds

Which means that Nolan took 100 seconds.

Glad I was able to help!!

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
