Mathematics

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}

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

ra1l [238]

Answer:

$ 154

Step-by-step explanation

Let the value of suitcase=x

x × 4.5% = 6.93 (converted the question into equation)

x × \frac{4.5}{100} = 6.93 (converted the percentage into fraction)

x = 6.93 x \frac{100}{4.5} (took reciprocal of 4.5/100 after moving it to the other side of the equation)

x = \frac{693}{4.5} (multiplied the values)

x = 154 $ (simplified the fraction)
