Answer:
(D) (a + 4)/2
Step-by-step explanation:
To solve, you need to subtract the first equation from the second.
9p = 3a + 1
<u>- 7p = 2a - 3</u>
2p = 1a + 4
Now, you need to rearrange the equation so that is equal to p.
2p = a + 4
(2p)/2 = (a + 4)/2
p = (a + 4)/2
This gives you answer choice D.
First number --- (2a-1)
middle number ---- (2a)
third number -----(2a+1)
2a-1+2a+2a+1=250
6a=250
a=250/6= 125/3
2a=2*(125/3)= 250/3 ---- is not a whole number that is contradicts to what is given, so sum cannot be 250
so
