Answer:
-q + p
Step-by-step explanation:
p - (p - q) - q - (q - p) = p - p + <u>q -q</u> - q + p
= 0 + 0 - q + p
= -q + p
See the attached figure to understand the problem
we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft
tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft
AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft
the answer is
The runners are 199.85 feet apart

Answer:
22 laps
Step-by-step explanation:
Lisa swam 6 fewer laps than four times of Amanda's laps.
Hence, L = 4A - 6
Again, Brynne swam eight more than twice as many laps as Amanda.
Hence, B =2A + 8
If Lisa and Brynne swam the same amount of laps, then
L = B
⇒ 4A - 6 = 2A + 8
⇒ 2A = 14
⇒ A = 7 laps
So, B = 2A + 8 = 2(7) + 8 = 22 laps
Therefore, Brynne swam 22 laps. (Answer)
