alright so p varies directly with q write an equation
anonymous

Don't you just multiply p•5?
anonymous
  • anonymous
100?
Nnesha
  • Nnesha
nope what's the equation p varies directly with q ?
Nnesha
  • Nnesha
y varies directly with q y = kx now replace y by p and x by q

sorry intnt gt disconnected
Nnesha

that's right solve for k
anonymous
  • anonymous
k=5?
Nnesha
  • Nnesha
right \[\huge\rm p=2q\] substitute q value solve for p
anonymous
  • anonymous
okay so what would it be when its 20?
Nnesha
  • Nnesha
yes right
anonymous
  • anonymous
?
Nnesha
  • Nnesha
ohh sorry i thought u said q would be 20 .-.
Nnesha
  • Nnesha
so replace q by 20 solve for p
Nnesha
  • Nnesha
\(\color{blue}{\text{Originally Posted by}}\) @Nnesha right \[\huge\rm p=2q\] substitute q value solve for p \(\color{blue}{\text{End of Quote}}\) q=20 plug in
