Answer:
25 grams
Step-by-step explanation:
Good effort, but that's not quite right.
Let's call the daily amount of fiber needed x.
One serving of oatmeal provides 16% of the daily amount, or 0.16 x.
The rest of the daily amount is 21 grams.
Together, they add up to the total daily fiber:
0.16 x + 21 = x
Solving for x:
21 = 0.84 x
x = 25
You need 25 grams of fiber daily.
Let's check our answer. 16% of 25 is 4. 4 plus 21 equals 25. So it checks out.
For this case we have the following functions:
We must find
By definition of composition of functions we have to:
So:
We have different signs subtracted and the sign of the major is placed.
Finally we have to:
ANswer:
Hb=3.5, hd=2.25, hb+hd=7,
From the third, we can say hb=7-hd and we are told that:
3.5hb+2.25hd=19.5 using hb found above in this equation gives you:
3.5(7-hd)+2.25hd=19.5
24.5-3.5hd+2.25hd=19.5
-1.25hd=-5
hd=4
