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
Answer:
Raw materials arrived in bigger towns with great frequency, which meant that these towns and cities could grow and develop faster.
Explanation:
The given question is about the text <em>California and Mesopotamia: Similarities and Differences.</em>
The options you were given are the following:
- Raw materials arrived in bigger towns with great frequency, which meant that these towns and cities could grow and develop faster.
- Overland transportation at that time was painfully slow and clunky, via simple wheeled pushcarts, or pack animals such as donkeys and camels.
- The canals provided a built-in transportation system for the Sumerian and Akkadian peoples who first settled the place.
- These rivers had many different branches, tributaries, feeding into them, creating a vast network of streams and canals.
The correct option is the first one as it directly states that water transportation helped towns and cities develop faster, making it crucial for the economical development of Mesopotamia. The rest of the options do not.
The second states why overland transportation wasn't the best, why it made things harder. There is nothing about water transportation.
The third simply states that the canals provided the Sumerian and Akkadian peoples with a transportation system. It doesn't say why that's good, unlike the first one.
The fourth would be the worst option as it doesn't include any information about transportation systems.
the correct answer is letter <u>b. Chronological order</u>
