There has been 28 years since 1985 to 2013, this becomes your x value. Plug x into the equation:

f(x) = (.65*28)+24.75
f(x) = 18.2+24.75
f(x) = 42.95

Answer:

see explanation

Step-by-step explanation:

Since the 2 figures are similar then the ratios of corresponding sides are equal, that is

\frac{8}{x} = \frac{18}{6} ( cross- multiply )

18x = 48 ( divide both sides by 18 )

x = \frac{48}{18} = \frac{8}{3} = 2 \frac{2}{3}

Similarly

\frac{5}{y} = \frac{18}{6} ( cross- multiply )

18y = 30 ( divide both sides by 18 )

y = \frac{30}{18} = \frac{5}{3} = 1 \frac{2}{3}
