-3y=33
-3/-3=33/-3
Y= -11
Well first you must find what 71/2 is equal to:
71 / 2 = 35.5
Now you should convert this to a decimal instead of a percent. All you have to do is move the decimal two places to the left when going from percent to decimal:
35.5% = .355
Now that you know the decimal value, you want to know what number is 12 35.5% of. To do this, think, if you were wondering what is 10% of 100, you would multiply 100 by .10 so in this case since you are going the opposite way, you would divide 12 by .335, which gives you:
35.8208955224
This can be approximated to:
≈35.82
Answer:
521
Step-by-step explanation:
f = factory
fTotal = 1,700
female workers = 640
0.4 female workers are under 35
0.25 male workers are under 35
1,700 - 640 = 1,060
Male Workers = 1,060
0.4% of 640 = 256
0.2% of 1060 = 265
256 + 265 = 521
521 of workers are under the age of 35
