35.c
Answer:
see explanation
Explanation:
(a)
3x + 5y = 8 → (1)
4x - 3y = 1 → (2)
multiplying (1) by 3 and (2) by 5 and adding the result will eliminate y
9x + 15y = 24 → (3)
20x - 15y = 5 → (4)
add (3) and (4) term by term to eliminate y
29x + 0 = 29
29x = 29 ( divide both sides by 29 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (1)
9(1) + 15y = 24
9 + 15y = 24 ( subtract 9 from both sides )
15y = 15 ( divide both sides by 15 )
y = 1
solution is x = 1 , y = 1
-----------------------------------------
(b)
6p + 4q = 20 → (1)
5p - 2q = 6 → (2)
multiplying (2) by 2 and adding to (1) will eliminate q
10p - 4q = 12 → (3)
add (1) and (3) term by term to eliminate q
16p + 0 = 32
16p = 32 ( divide both sides by 16 )
p = 2
substitute p = 2 into either of the 2 equations and solve for q
substituting into (1)
6(2) + 4q = 20
12 + 4q = 20 ( subtract 12 from both sides )
4q = 8 ( divide both sides by 4 )
q = 2
solution is p = 2 , q = 2
The Northwest Passage achieved the crossing from the Atlantic Ocean to the Pacific Ocean through the Canadian Arctic Archipelago. Crossed completely by Norwegian explorer Roald Amundsen from 1903 to 1906, the passage opened a new trade route for Europeans. Before that, the Vikings had used the passage as a trade route with the Inuits.
In 1609, Henry Hudson's voyage along the Hudson Bay triggered a Dutch settlement in New York and the area around the Hudson River.
Race means that from where you are from like from India, China, Mongolia, Mexico, Africa etc. So the question basically means Where are you from?
