Janelle purchased the same number of cupcakes as Riley did. They each left some at home and brought some to school.

Which equation could represent the way they separated their cupcakes?
A) 8 + 16 = 14 + 11
B) 9 + 15 = 16 + 7
C) 11 + 13 = 18 + 6
D) 20 + 4 = 11 + 12

-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

answer: chelsea has 55 brushes

step-by-step explanation:

5 x 11 = 55

5 + 55 = 60
