21. Navigation A boat race runs along a triangular course marked by buoys A, B, and C. The race starts
with the boats headed west for 2500 meters. The
other two sides of the course lie to the north of the
first side, and their lengths are 1100 meters and 2000
meters. Draw a figure that gives a visual representa-
tion of the problem, and find the bearings for the last
two legs of the race.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

50x5=$250
