Answer:
Step-by-step explanation:
(x + 200)20 = 200(10) + x(40)
20x + 4000 = 2000 + 40x
2000 = 20x
X = 100 mL
Answer:
The man covers 200 ft in 40 seconds.
Step-by-step explanation:
A person is moving on the sidewalk from one end to the other end.
He walks 40 feet in 8 seconds.
Therefore his speed = 
= 
= 5 ft/
He covers the sidewalk distance at a rate of 5 feet every second.
To calculate the time taken to cover 200 ft,
time = 
time =
<u>time = 40 seconds</u>
Hence the man covers 200 ft in 40 seconds.
Angle COD equals angle AJL
Angle DCO equals Angle LAJ
Side OC equals side JA is all true expect for the first one
