Because there are no parentheses, I'm assuming you're asking for how to factor this using the GCF, which can be done like so:
9−12x+6y
Factor a 3 out of this expression.
3(3 - 4x + 2y)
The expression has been simplified using the distributive property in reverse.
The band has sold 1,890,000 copies or 1.89 x 10^6
Answer: 27/50
Explanation
An equation for the ellipse ( standard form ):
x²/a² + y²/b² = 1
Here is: a - semi-major axis and b - semi-minor axis.
Radius of the moon is 1,000 km and the distance from the surface of the moon to the satellite varies from 953 km to 466 km.
a = 1,000 + 953 = 1,953 km
b = 1,000 + 466 = 1,466 km
Answer:
The equation is x² / 1,953² + y² / 1,466² = 1
or: x²/3,814,209 + y²/2,149,156 = 1
The giraffe (using the ruler) is 11 cm.
1 cm : 50 cm
Multiply both sides by 11.
11 cm : 550 cm
There are 0.01 meters in 1 centimeter.
Multiply 550 cm by 0.01.
(550)(0.01) = 5.5
The giraffe's real length is 5.5 meters.
