Answer:
B. Mexico and Canada (which, along with the United States, are in North America)
Answer:
Correct answer is North America, which were a part of the so-called continent Laurasia. It was a continental mass, that included Asia, Europe, Greenland and North America.
Explanation:
According to geologists this supercontinent existed until between 66 and 30 million years ago. According to them actually there were continents, one in northern hemisphere, called Laurasia and the one in the southern hemisphere - Gondwana.
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
