Mathematics

Answer:

x = 7

Step-by-step explanation:

The proportion is

14/6 = 21/(3x - 12)                 Cross Multiply

14*(3x - 12) = 6*21                 Remove the brackets and combine

42x - 168 = 126                     Add 168 to both sides

42x = 126 + 168

42x =  294                           Divide by 42

x = 294/42

x = 7

There are 35 people in a room. There are
Degger [83]

Answer:

Male=21 Female=14

Step-by-step explanation:

So the problem would be (f)+(f+7)=35

first you would subtract 7 from 35

Now you have (f)+(f)=28 or 2f=28

Then you divide both sides by two

f=14

and since we know there is 7 more males then the answer is

m=21
