Answer:

The faster train goes 60mph

Step-by-step explanation:

s= speed

s+20 is the faster train.

Then you are given:

200/s+s+20=2

200=2*(2s+20)

4s+40=200

4s=160

s=40 is the slower train

40+20= speed of faster one

s=60 ;)

Which expression is equivalent to -0.55 – 0.47a + a?
Leto [7]

Answer:

-0.55 + 0.53a

Step-by-step explanation:

              -0.55 – 0.47a + a

 To find an expression equivalent to this, we must simplify the equation to a reasonable extent;

         -0.55 – 0.47a + a

      = -0.55 + 0.53a

      = 0.53a - 0.55

The expression equivalent to the given one is -0.55 + 0.53a  or 0.53a - 0.55
