Answer:

y= 11.4

Step-by-step explanation:

In an equilateral triangle, each angle is the same

180/3=60

So each angle equals 60

5y+3 =60

Subtract 3 from each side

5y +3-3 = 60-3

5y = 57

Divide by 5

5y/5 = 57/5

y = 11.4

Each vertex can be found using two simple steps.

1) The number being added or subtracted from x.

-The x coordinate of your vertex is the opposite of that number.

2) The number after the absolute value symbol.

Which ratio is equivalent to 3:9? 24:54 18:54 36:81

docker41 [41]

Answer:

18:54

Step-by-step explanation:

We have to simplify these ratios.

If the most simplified form of the ratios are equal, they are equivalent

3:9

$r = \frac{3}{9} = \frac{1}{3}$

24:54

$r = \frac{24}{54} = \frac{12}{27} = \frac{4}{9}$

18:54

$r = \frac{18}{54} = \frac{9}{27} = \frac{3}{9} = \frac{1}{3}$

Same ratio as 3:9, so 18:54 is equivalent to 3:9

36:81

$r = \frac{36}{81} = \frac{12}{27} = \frac{4}{9}$
