3x + 2y = 20   x = 3

substitute for x

3(3) + 2y = 20

multiply

9 + 2y = 20

subtract on both sides.

(9 - 9) + 2y = (20 - 9)

simplify

2y = 11

divide bothe sides by 2

2y/2 = 11/2

Evaluate 11/2 into a mix number

y = 5 1/2

y = five and one half.

Answer: 3/3 since they have the same numerator and denominator you can simplify it down to 1.

Good afternoon.

Hey, Bored.

30/3 = 10

so 10 x 2 = 20

30 - 20 = 10

then 30/5 = 6

so 6 x 1 = 6

10 - 6 = 4

9.   The scale factor between the larger figure and the smaller one is   =  10 : 8    =   5 : 4     

Since perimeter is a linear measure, it has the same ratio, 5 : 4

The area ratio is  the square of the scale factor  =  25 : 16 

10.  The scale factor  between the larger figure and the smaller one is 57 : 24

So.....the area of the larger figure is   (scale factor)^2  as much as that of the smaller figure

So....

564  (57/24)^2  ≈  3181  m^2
