Answer:
6.67408 × 10^-11 m^3 kg^-1 s^-2
Step-by-step explanation:
F = G M 1 M 2 d 2 , where F is the gravitational force between two point masses, M1 and M2; d is the distance between M1 and M2; G is the universal gravitational constant, usually taken as 6.670 × 1011 m3/(kg)(s2) or 6.670 × 10−8 in centimeter–gram–second units. a = F M 1 = G M 2 r 2 .
Make drawing (see attachment)
do big rectangle minus triangle
big rectangle area=lenght timess width=22 times 33=726 square feet
triangle=1/2 times base times height=1/2 times 9 times 10=45 square feet
rectangle-triangle=726-45=681 square feet
Answer:
x = 6
Step-by-step explanation:
You <em>multiply</em> both sides of the first equation by 4.
Then you have . . .
-2x + 4y = 3 and y - 2x = 3 .
If you want to get rid of a fraction, you multiply it by itsdenominator.
BUT ... whatever you do to one term on one side of the equation, you
have to do the same to <em>all</em> the terms on that side, AND then you have to
do the same thing to all the termson the OTHER side.
