3 0
Equation.
1/5 x - 2/3 y = 30

     y= 15

Substitution.
1/5 x - 2/3 (15) = 30

1/5 x - 10 = 30

1/5 x = 30 + 10

1/5 x = 40

   x = 200.

The length f a rectangle is 3 ties its width, the perimeter of it is 24cm. what is the area of it?
andreyandreev [35.5K]

Answer: 27cm²

Step-by-step explanation:

lets take the width as x and length as 3x( since length is 3 times the width)…

Perimeter of the rectangle is 24 cm( 2*(l+b))= 2×(3x+x):24

2×4x=24

8x=24

X( width): 24/8=3cm

Length= 3x: 3*3=9cm

Area of the rectangle: ( l*w)= 9×3: 27cm²

Circled one I need help with thank you!!
Mashcka [7]

Formula-

If a set has “n” elements, then the number of subset of the given set is 2n and the number of proper subsets of the given subset is given by 2n-1. Consider an example, If set A has the elements, A = {a, b}, then the proper subset of the given subset are { }, {a}, and {b}

Symbol that can be used-

The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".
