six p minus nineteen is less than twenty-nine
6p-9<29
6.3
\[6p - 19 < 21\]This is basically an equation with a less than sign instead of an equals sign. So what do you do to solve an equation?
what is p?
6.3
@DLS i was trying to get him to figure it out on his own.
You have to isolate p. That means you have to get only p on one side and everything else on the other side.
So you subtract the other stuff on p's side so it is alone. So in this case we subtract (or in this case we actually add) 19 to -19, which makes it 0. In other words we now have p alone.
And the addition/subtracton property of equality says that if you subtract or add something to both sides, it will still be equal. So we added 19 to -19, now we have to add 19 to 21. 19 + 21 = 40.
Wait wait wait. It's 29 that you add to. Sorry, I messed up.
So you add 19 to 29, which is 48. Then you have \[6p < 48\]
then you just divide 6 by both sides:\[\frac{ 6p }{ 6 } < \frac{ 48 }{ 6 }\]Which cancels out the 6 in 6p so it ends up as just p. Then 48 divided by 6 is 8, so the answer is p < 8.
okay thanks
@yoyogators u still here?
