Answer:
If he eats a bowl of cereal and two protein bars today, Fernando's daily intake of Iron will be equal to this equation: <em>11.8 + (3.6 * 2) = m</em>
Step-by-step explanation:
3.6 * 2 = 7.2
11.8 + 7.2 = 19 milligrams of Iron.
The answer is X = 5 because first you have to take away 2x from that side so u minus 2x from 4x that gives u: 72 + 2x = 82 then you have to minus 72 from both sides and that gives you 2x = 10 once you have that you divide both sides by 2 because you want the X by itself and once you get that X = 5. Hope this helped!
The third side must be greater than the difference of the other 2 sides and less than the sum of the other 2 sides.
5 and 12 SUM = 17
DIFFERENCE = 7
The 3rd side must be greater than 7 and less than 17
So, the third side could be 9 or 11.
