Answer:

BC = 28 $\frac{1}{3}$ ft

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AX}{AB}$ = $\frac{XY}{BC}$ , substitute values

$\frac{12}{20}$ = $\frac{17}{BC}$ ( cross- multiply )

12BC = 340 ( divide both sides by 12 )

BC = $\frac{340}{12}$ = $\frac{85}{3}$ = 28 $\frac{1}{3}$

A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.

B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20

Add equations
x=5

Plug x in
5+y=20
y=15

Final answer: 5 cheese wafers, 15 chocolate wafers
