Which of the following is equivalent to 5:4? * 25:15
20:19
30:20
10:8
15:16
100:85

the answers equivalent to 5:4 is 10:8

Step-by-step explanation:

The reason I only chose 10:8 is because all the other answers are not even multiples of 5 or 4 or they were multiples of 5 and 4 but they were not multiplied by the same number.

Example:

25:15 = okay so 5 can go into 25, 5 times but 4 cannot go into 15

20:19 =  okay so 5 can go into 20, 4 times but 4 cannot go into 19

30:20 = though 5 can go into 30 and 4 into 20 they are not multiplied by the same number

15:16 = though 5 can go into 15 and 4 into 16 they are not multiplied by the same number

and last but not least 100:85 = okay so 5 can go into 100, 20 times but 4 cannot go into 85

So it leaves 10:8= 5 can go into 10, 2 times and 4 can go into 8, 2 times so this is your answer.

Hope this helps you!!!

5 * 2 = 10 and 4 * 2 = 8

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
