Answer:
-0.6n+0.2p
Step-by-step explanation:
2.8n-0.9p-3.4n+1.1p
You can only add the numbers with the same variables (n,p)
2.8n-3.4n-0.9p+1.1p
= -0.6n+0.2p
Answer:
X>30
Step-by-step explanation:
Well the brackets or parethesis or absolutvalue sign thingy doens’t ,matter. Out of all the signs that won’t do anything at all.
Solve it normally
add 28 on both sides
2x>60
60/2=30
x>30

Answer:
the present age of the father be x and the present age of the son be y.
It is given that man is 24 years older than his son that is:
x=y+24
x−y=24..........(1)
Also, 12 years ago, he was five times as old as his son that is:
(x−12)=5(y−12)
x−12=5y−60
x−5y=−60+12
x−5y=−48..........(2)
Now subtract equation 1 from equation 2 to eliminate x, because the coefficients of x are same. So, we get
(x−x)+(−5y+y)=−24−48
i.e. −4y=−72
i.e. y=18
Substituting this value of y in (1), we get
x−18=24
i.e. x=24+18=42
Hence, the present age of the father is 42 years and the present age of the son is 18 years.
