Answer:
5/15 - 2/15
Step-by-step explanation:
I think its 206 because you'll have to change 5% into a decimal and you'll
get 0.05 because you move the decimal place to the left 2 times. Then multiply
2,600 to 0.05 to get what the population decreasing for a year, (130) then multiply is by 2 (for 2 years) and you'll get
260 students.

Answer:
30=2r+r
r=5
Step-by-step explanation:
30=2r+r would be the answer for the first question because the red line, 30, is equal to the line 2r and r.
r=7.5 because 30=2r+r (combine like terms)➡️ 15=3r (divide both sides by 3)➡️ 5=r
