you replace every p with 5 and every q with 4.
therefore
2(5) + 4= ?
14=?

when p/q=5/4 then==> p=5 &q=4
consequently 2p+q=(2x5)+4=14

p/q=5/4
Therefore, 4p=5q
2p=2.5q ---------------(1)
Now, 2p+q= 2.5q+q (putting value of 2p from equation 1)
=3.5q
Basically, this can't be resolved as there is only one equation for two unknown variables. 'q' can have many values.

2p+q
= q(2p/q+1)
= q(10/4+1)
= 3.5q
It is undetermined (with infinite number of solutions) because you have two variables with only one restriction.

There are an infinte number of possible solutions to 2p + q.

it would come out as a variable. as womeone else said, there are an infinite number of answers, because p/q=5/4 is a ratio.
7/2q= ?
or
14/5p=?

p=5
q=4
2(5) + 4 = 14

18, 2(5+4)
5+4 is 9
2(9)
2 x 9 = 18

It can't be resolved. Its a ratio with two variables
2007-08-06 03:13:18 · answer #9 · answered by jagat s 1 · 1⤊ 0⤋
p=(5/4)q
thus,
2(5q/4)+q
(5p/2)+q
7q
........ i don't know what this anwser but if 2p+q=x, where x= 1,2,3,.....
if you know this anwser tell me about it at my email(mr.khai_irwan@yahoo.com)..
