Answer:
Step-by-step explanation:
Begin by isolating the term with the r in it. Do that by subtracting 8.9 from both sides:
9.5r = -110.445 - 8.9 and
9.5r = -119.345 Divide both sides by 9.5 to get
r = -119.345/9.5 and
r = 12.56263158 (or you could leave it as a fraction)
The answer is 11.51. 8.9+9.5r=-100.445, so we have to remove the 8.9 by subtracting it from both sides. 9.5r=-109.345, but now we have to get r by itself, so we have to divide both sides by 9.5 r=-11.51
