Step-by-step explanation:
Maria can do full job in 13 hours,
she can do 1/13 part of job in one hour
Felipe can do full job in 15 hours,
he can do 1/15 part of job in 1 hour
Together they can do:
- 1/13 + 1/15= 28/13*15= 28/195 of job in 1 hour
to complete full job they need:
- 1 ÷ 28/195= 195/28 ≈ 7 hours
Answer:
Step-by-step explanation:
put x=1 ,y=5
y≥4x
5≥(4×1)
5≥4
which is true.
again 5≤1+2
5≤3
which is not true.
so, no (1,5) is not a solution.
To be a solution it should be true for both.
