The miles previously covered by algae is 6 miles
let m represent the miles of the coastline covered by algae before the clean-up
fraction of miles covered after the clean-up = x m =
miles covered after the clean-up = 2 miles
= 2 miles
to determine the value of m, make m the subject of the formula.
To do this, take the following step :
multiply both sides of the equation by 2
m = 2 miles x 3
m = 6 miles

X=4 BC=13
steps
set both equations equal to each other m, 3x+1=2x+5
subtract 2x from both sides, x+1=5
subtract 1 from both sides, x=4
then plug in 4 for x, 2(4)+5 so BC= 13
Answer:
y=3x+5
Since it's already 5 cm we have +5
every month it would go up by 3 cm so we have 3 and x is to represent the # of months.
