Answer:

3x + 2y = 315 -----(1)

2x + 4y = 450 -----(2)

from (1) 3x + 2y = 315

2y = 315-3x

y = 157.5 - 3/2x ---- (3)

substitute (3) into (2)

2x + 4y = 450

2x + 4(157.5 - 3/2x ) = 450

2x + 630 - 6x = 450

-4x = -180

x = 45 ---- (4)

substitute (4) into (3)

y = 157.5 - 3/2x

y = 157.5 - 3/2(45)

y = 90

Find the exact area of each shaded region

Anton [14]

$\bf \textit{area of a circular ring}\\\\ A=\pi (R^2-r^2)~~ \begin{cases} R=larger\\ \qquad radius\\ r=smaller\\ \qquad radius\\[-0.5em] \hrulefill\\ R=12\\ r=7 \end{cases}\implies A=\pi (12^2-7^2) \implies A=95\pi$
