first of all add 80 to both sides: -np-80<60 -np<140 now for what do you need to solve for? n or p?

solve -np-80<60 for N
AlexandervonHumboldt2
  • AlexandervonHumboldt2
last thing we got is -np<140 now we divide both sides by p: -np/p<140/p -n<140/p now divide both sides by -1 and flip the sign < to > n?

ok next question solve 2a-5d=30 for d
anonymous
  • anonymous
2a-5d=30 Subtract 2a from each side -5d=30-2a Divide both sides by -5 \[d=\frac{ 30-2a }{ -5 }\]

Could also be written:\[d=\frac{ 2a }{ 5 }-6\]
