A collector has 180 movie posters and 120 band posters. She wants to sell 45 movie posters but still have her poster collection maintain the same ratio of 180:120. If she sells 45 movie posters, how many band
posters should she sell? Complete the explanation to find out how many band posters she should sell.
Her current ratio of movie posters to band posters is 180:120. If she sells 45 movie posters, she will have___ left.
180/120 = 135/__ , so she should sell ___ band posters.

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

may i see the picture? it would a lot, xox
