Thomas has constant speeds for both running and walking. When a down-escalator is moving, Thomas can run down it in 15 seconds or walk down it In 30 seconds. One day, when the escalator was broken (and
stationary), it took Thomas 20 seconds to run down it.
How long, in seconds, would it take Thomas
walk down the broken escalaton?

the answer is simply just 6n add the two together as they have an n

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

2 over 5 and 4 over 15

don’t know last one sorry
