Answer:
a. x/y = 2 b) y/x +y =1/3 c) x-y/y= 1 d) y/x = 1/2
Step-by-step explanation:
Solve for
a) x/y
as we know x +y/y = 3
x+y= 3y
x= 3y-y
x= y(3-1)
x/y= 3-1
x/y = 2
b) y/x+y
as we know x +y/y = 3
x+y = 3y
1= 3y/x+y
1/3 = y/x+y
So y/x +y =1/3
C) x-y /y
as we know x +y/y = 3
x +y = 3y
subtracting 2y from both sides
x +y -2y = 3y- 2y
x-y = y
dividing both sides by y
x-y/y = y/y
x-y/y= 1
d) y/x
as we know x +y/y = 3
x +y = 3y
x= 3y- y
x= 2y
dividing both sides by x
x/x = 2y/2x
1 = 2 x (y/x)
1 / 2 = y/x
Or y/x = 1/2
Best of luck.

Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet
№1. Given: r=8 ft, π≈3.14
C=2×π×r=2×3.14×8=50.24=50.2 ft
A=π×r²=3.14×64=200.96=201 ft²
Answer: 50.2 ft; 201 ft²
№2. Given: D=11 cm, π≈3.14
d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm
C=2×π×r=πD=3.14×11=34.54=34.5 cm
A=π×r²=3.14×(5.5)²=94.985=95 cm²
Answer: 34.5 cm; 95 cm²
