Video streaming company a charges a one-time $40 membership fee and $2 per video stream. video streaming company b charges a one-time $20 membership fee and $4 per video stream. let the variable s represent the amount of videos streamed and let the variable c represent the cost. for how many video streams will the cost be the same for both companies? which system of equations can be used to solve this problem? a: {c=40s+2c=20s+4 b: {c=42sc=24s c: {c=40−2sc=20−4s d: {c=40+2sc=20+4s

D: {c=40+2s; c=20+4s

Step-by-step explanation:

"company A charges a one-time $40 membership fee and $2 per video stream"

c = 40 + 2s

"company B charges a one-time $20 membership fee and $4 per video stream"

c = 20 + 4s

D: {c=40+2s; c=20+4s

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
