3(4x+y=-9)

6x - 3y = -27

12x + 3y = -27

6x - 3y = -27

18x = -54

x = -3

4(-3)+ y = -9

-12 + y = -9

The program director at a botanical garden surveyed 75 of their annual members about the number of times they visit the gardens
Tatiana [17]

Answer: C) 165 annual members

Step-by-step explanation:

Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.

Out of the 75 surveyed, the total number of those are:

= 9 + 12 + 3

= 24

That would give a percentage of:

= 24 / 75

= 32%

This means that the best estimate for those who will visit more than 3 times is 32%.

Out of the total number of 516, that is:

= 32% * 516

= 165 members

Can anybody help me please? I'll give brainlest for correct answer​
Hoochie [10]

Answer:

1) 40 degrees

2) 140 degrees

3) 110 degrees

4) 70 degrees

5) 70 degrees

Explanation:

Use the curved protractor they have created you, and count every dash as 10 degrees. Keep in mind that the whole thing equals 180 degrees, and half would equal 90 degrees. Some call it a right angle.

Let me know if my answer is correct for the other users that will see this message. Thank you!
