Answer:
500 times
Step-by-step explanation:
They breathe 20 times per minute for 25 minutes
20(times per minute) x 25(minutes) = 500
y = -19
I started by adding 18 to both sides(inverse operation) then dividing by -2 to isolate the variable. What you do to one side must be done to the other
First, you make 9 into a fraction which would become 36/4
then, subtract 9/4 from both sides so that would give you 3/4x = 27/4
then divide each side by 3/4 (same thing as multiply by its reciprocal) and that would give you x=9
