9) find the area of the actual garden by doing 12x14, then do the water pond and since it's a square do 4x4. Then subtract the area of the pond from the garden to find your answer

10) I would do 150 divided by 6 (so the total surface area divided by the number of sides) and got 25. So 25 would be the area of one side of the cube. To find a side length take the square root of the area and your answer will be 5

Explain answer ! Will give brainlst

Answer:

x = 4, y = 2

Step-by-step explanation:

Start by multiplying the first equation by 2:

2x + 2y = 12 --> 4x + 4y = 24

Subtract the second from the first:

4x + 4y = 24

- 5x + 4y = 28

4x - 5x = -x

4y = 4y = 0

24 - 28 = -4

so you end with -x + 0 = -4

Solve for x to get x = 4

Plug x = 4 back into 2x + 2y = 12 to find y.

2(4) + 2y = 12

8 + 2y = 12

2y = 4

y = 2

What is the solution to the equation below? 5 - n/2 = 12

Zarrin [17]

Step-by-step explanation:

5 - n/2 = 12

10/2 - n/2 = 12

n = (12 × (-2)) + 10

n = (-24) + 10

n = -14

Let's prove it :

$5 - ( - \frac{14}{2} ) \\ = \frac{10}{2} + \frac{14}{2} \\ = \frac{24}{2} \\ = 12$

Conclusion :

5 - n/2 = 12

5 - (-14/2) = 12

and

n = -14

Answer:

the arc length is 555.17 cm

Step-by-step explanation:

The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·

You want to find the distance the golf club travels when the golfer swings the club.

First you need to subtract 25° from 360°

360° - 25° = 335°

now you need to convert 335° into radians

radians = degrees ·

radians = 335° · you multiply 335° by

radians = 335/180 then you simplify

radians = 67/36

335° = 67 $\pi$ /36

Now we plug everything we know into the equation s = rΘ

s = rΘ

s = 95 (67 $\pi$ /36) first multiply 67 by 3.14

s = 95 (210.38/36) divide 210.38 by 36

s = 95 (5.843888889) and multiply 95 by 5.843888889

s = 555.1694444 *remember to simplify to the nearest hundredth

s = 555.17 cm

hope this helps! if u have any questions, let me know!
