Answer:

Step-by-step explanation:

5.  The opposite angles of a cyclic quadrilateral sum to 180 so

9y + 5 + 18x + 4 = 180  and

9y - 9 + 21x + 6 = 180

Solve this system to find x and y.

7. Solved in the same way.

Answer:

X=4 y=11

Step-by-step explanation:

9y+5+18x+4=180 9y=171-18x

9y-9+21x+6=180 9y=183-21x

171-18x=183-21x

3x=12 x=4 9y=171-72=99 y=11

the distance between Nick and Sara's house is 546m. Nick can walk 1.3 m/sec. Using the formula d=rt, where d is distance, r is r
maks197457 [2]
D=rt and we are told d=546 and r=1.3m/s so

1.3t=546  divide both sides by 1.3

t=420 seconds so

420s(min/60s)=7 min

So it takes him 7 minutes to walk to Sara's house.

Bus A leaves the station every 30 mins bus b leaves the station every 20 mins at 10 am both buses leave the station together wor
denis-greek [22]

Answer: 11am

Step-by-step explanation:

To solve this, we have to calculate the lowest common multiple of 20 and 30. This will be:

20 = 20, 40, 60, 80, 100

30 = 30, 60, 90, 120, 150.

Here, the lowest common multiple is 60.

Therefore, we add 60 minutes to 10am. This will be:

= 10am + 1 hour

= 11 am

The next time that both buses leave at the same time would be 11am

which ordered pair is a solution of the equation y=4x-7 A. only (2,1) B. only (4,9) C. Both (2,1) and ( 4,9) D Neither
Sphinxa [80]

Hey there! :)

Answer:

C. Both (2,1) and (4,9)

Step-by-step explanation:

To solve this question, simply plug in the coordinates of answer choices given into y = 4x - 7:

A.

1 = 4(2) - 7

1 = 8 - 7

1 = 1. A is correct.

B.

9 = 4(4) - 7

9 = 16 - 7

9 = 9. B is correct.

Therefore, the correct answer is C. Both (2,1) and (4,9) are solutions to this equation.
