All right sy Match members We've got another directive from
- 00:05
the head office here Solve for p all right so
- 00:12
we got the eagles p minus point to pee All
- 00:15
right So how do we solve for p p equals
- 00:18
what That's we got two D'oh Well someone for p

looks a bit scary here because there's two p's and
- 00:23
one has a decimal coefficient and seeing the terms as
- 00:27
like terms help simplify the right side And while placing
- 00:30
a one in front of the p makes the values
- 00:33
that should be subtracted way clear So i got t
- 00:35
equals one p minus point to p or t equals
- 00:39
point eight p all right well that makes it a
- 00:41
lot easier We'll divide both sides by point eight We
- 00:45
got t over point eight is p or p equals
- 00:48
t over point eight All right Well it's not even
- 00:51
answer choice We're looking here You see it anywhere Nope
- 00:54
Ain't there It's a problem Well none of the answer
- 00:56
choices air decimal So we've got to make this thing
- 00:58
a fraction so let's Think about it Making our equation
- 01:02
conform A cement of changing point Eight two eight over
- 01:06
ten right You'd agree Those were the same thing So
- 01:09
let's Think about this instead of point Eight times P
- 01:11
let's Make it eight tense times being reduced that to
- 01:14
four fifths times P and all right but we've got
- 01:18
a solve for p so we gotta multiply both sides
- 01:21
by i five force And if we do that well
- 01:24
guess what we got P equals five force t or
- 01:27
five t over four which is answer c and we're 00:01:30.864 --> [endTime] done
