Answer:
20
Step-by-step explanation:
Since chord AB and DE are at equal length from the centre, they are equal in length.
AB = DE
3x-7 = 5(x-5)
3x-7 = 5x-25
-7+25 = 5x -3x
18 = 2x
Dividing both side by 2
x = 9
Now
AB = 3(9)-7
= 27 -7
= 20
To get the answer we can subsittute first equation into second.
x+6y=20
y+6+6y=20
6+7y=20 /-6
7y=14 /:2
y=2
Now we can back substitute
x=y+6
x=2+6
x=8
Finally we get
x=8
y=2
Answer:
3:50pm
Time Keisha went to the park- 1:30pm
Time spent for hiking- 1hour 35 minutes
Time spent at the picnic area- 45 minutes
1: 30pm
<u>+1. 35mi</u>n
<u> 2: 65pm</u>
But 60 minutes is 1 hour so the 65 will be changed to 1 hour 5 minutes making it
3: 05pm
3: 05pm
<u>+0: 45min</u>
<u> 3: 50pm</u>
Hence the time Keisha left the park was 3:50pm
