Consuetive even integers are 2 apart
so the numbers are x, x+2, x+4
so
the sum
x+x+2+x+4=90
3x+6=90
minus 6 both sides
3x=84
divide both sides by 3
x=28
x+2=30
x+4=32
the numbers are 28,30,32
They give you an "x =" statement so you plug in the right side of the equals sign into the first equation wherever x appears. So...
y = 10 - 2(y - 4)
y = 10 - 2y + 8
y = 18 - 2y
y + 2y = 18
3y = 18
y = 6
Now we plug in this result for the y-value into the "x =" statement.
x = 6 - 4
x = 2
Your answer is (2, 6)
Answer:
The area of land is 0.067 million squared miles.
Step-by-step explanation:
The shape of a planet is sphere.
The surface area of a sphere is .
Given that, the radius of the planet is approximately 4012 miles.
Total surface area of the planet is
= 202,351,5224.6 squared miles
=0.202 million squared miles
of the plane surface is covered by water.
of the plane surface is covered by land.
The area of land is =
= 0.067 million squared miles
Answer:
w = 0.5
Step-by-step explanation:
w represents the width of the frame
Area of the picture and the frame is
(2 + 2w)2
Area of picture is
22
Area of the frame is
(2 + 2w)2 - 4 = 5
(2 + 2w)2 = 9
2 + 2w = 3
2w = 1
