Wheat, barley, and jujube were domesticated in the Indian subcontinent by 9,000 BC, soon followed by sheep and goats. Barley and wheat cultivation, along with the domestication of cattle, primarily sheep and goats; followed in Mehrgarh culture by 8,000–6,000 BC<span>.</span>
Atmosphere because there is only 4 spheres biosphere, hydrosphere, and geosphere which have nothing to do with space
Answer:
Lenght of RS= 2
Explanation:
We were told that Points R, S, and T are collinear, then RT, RS and ST are on straight line which can be expressed linearly as;
RS + ST= RT.......eqn(1)
We know that
RS = 2x – 4
ST = 3x + 2
RT = 13.
Then just substitute these into eqn(1)
(2x - 4) + (3x + 2)= 13
If you simplify and collect like-terms
bracket we have
2x+3x=13+4
5x =15
x=15/5
x = 3
To find RS, Then substitute the value of x into equation of RS, we have
RS = 2x – 4
RS = 2(3) - 4
= 6 - 4
= 2
Therefore, the length of RS =2
