Answer:
a) 5xy + 9yz + 3zx + 5x - 4y
Step-by-step explanation:
→ (7xy + 5yz - 3zx) + (4yz + 9zx - 4y) + (-3xz + 5x - 2xy)
→ (7xy - 2xy) + (5yz + 4yz) + (-3zx + 9zx - 3xz) + (5x) + (-4y)
→ 5xy + 9yz + 3zx + 5x - 4y
Hence, option (a) is the correct answer.

Answer:
-2 3/5, -9/4, 1.2, 7/4
Step-by-step explanation:
First, unmix the mixed numbers.
-9/4 = -2 1/4.
Which is greater?
1/4 vs. 3/5
Answer: 3/5 So...
-2 3/5 would be the least.
Then there would be -2 1/4
Then, it would be 1.2 because 1.2 is smaller than 7/4.
Therefore, this pattern would be the correct answer...
From Least to greatest=
-2 3/5, -9/4, 1.2, 7/4
