3x + y = 12 (multiply whole equation by 3)
x - 3y = 24

9x + 3y = 36
x - 3y = 24
10x = 60
x = 60 / 10
x = 6
puting the x value in 1st equation
3 (6) + y = 12
18 + y = 12
y = 12 - 18
y = -6

Answer x = 6
              y = -6

The shaded area and the diameter
masha68 [24]

Answer:

  • 15.25 cm²

Step-by-step explanation:

<u>The diameter is the hypotenuse of the triangle:</u>

  • d = √8²+6² = √100 = 10 cm

<u>Area of the semicircle:</u>

  • A = 1/2πr² = 1/2(3.14)(10/2)² = 39.25 cm²

<u>Area of the triangle:</u>

  • A = 1/2bh = 1/2(6)(8) = 24 cm²

<u>Shaded area:</u>

  • 39.25 - 24 = 15.25 cm²

D = 2C
J = 1/3D
J = C - 1

J = 1/3D
J = 1/3(2C)
J = 2/3C

2/3C = C - 1
2/3C - 3/3C = -1
-1/3C = -1
C = -1 * -3
C = 3...there are 3 cats
