For the first question, the answer is 25/14.
Because 14x = 25y Which means x must equal more than y. And 25/14 is the only answer like this.
For the second question, the answer is 30 x 18.
30/5 = 6 18/3 = 6 18 + 18 + 30 + 30 = 96
So, both the perimeter and the ratio is correct with this answer.
For the third question, the first answer is correct.
x < -4 and only a negative number can be less than another negative. Also, the negative must have a higher value to be less than another negative.
For the last question, the last answer is correct. no explanation for this one, it would take too long ;)

(24y⁵/15x⁸)÷(8y²/4x⁴).
(8y⁵/5x⁸)÷(2y²/x⁴)=8y⁵/5x⁸×x⁴/2y²=4y³/5x⁴
Answer:
a) (2,2)
Step-by-step explanation:
as X=2 and y=2
y=x
Answer:
30
40 - 5x
Step-by-step explanation:
Caroline took a test that is worth 40 total points. With 2 questions wrong, she wouls have 30/40 pints
2 × 5 = 10
40 - 10 = 30
If Caroline got x questions wrong, she would have a score of 40 - 5x.
