Hello there! I can help you! 58,500 female doctors makes up 17.9% of all registered doctors. To find the total amount of registered doctors, we can write and solve a proportion. Set it up like this:
58,500/x = 17.9/100
This is because 58,500 is part of the whole, which is represented by x. 17.9% is part of 100%. Let's cross multiply the values. 58,500 * 100 is 5,850,000. 17.9x * x is 17.9x. That makes 5,850,000 = 17.9x. Now, divide each side by 17.9 to isolate the x. 17.9x/17.9 cancels out. 5,850,000/17.9 is 326,815.6425 or 326,816 when rounded to the nearest whole number. Let's check this. 326,816 * 17.9% (0.179) is 58,500.064, which is a little off, but is very close to 58,500, and rounds off to that. x = 326,816. There are about 326,816 registered doctors in a recent year.
To do this, subtract 6 from both sides. − 3_x_ + 6 − 6 > 12 − 6. −3_x_ > 6. Now divide both sides of the inequality by −3. Since you're dividing by a negative number, you need to flip the inequality sign.
