Answer:
Step-by-step explanation:
if f(x)=3x-1 and g(x)=2x+5 then
f(x)-g(x)=3x-1-(2x+5)
f(x)-g(x)=3x-1-2x-5
f(x)-g(x)=x-6
Answer:
<h2>18 hours</h2>
Step-by-step explanation:
This problem is on Combined work rate
Step one:
given data
let the secretary take x hours to finish one job
so the clerical worker will take 2x hours to finish one job.
Both of them working together will take 6 hours
Step two:
The combined work formula is
T/A+T/B=1
Where T= time working together
A= time the Clerical worker spent alone
B= time the secretary spent alone
substituting we have
6/2x+6/x=1
solve for x
6+12/2x=1
18/2x=1
9/x=1
cross multiply
x=9 hours
the clerical worker take 2x hours
2*9= 18 hours
