The doctor recommended avery has 11 milligrams of iron per day. by how much did she exceed the doctor’s recommendations if she ate a bowl of shellfish containing 16 milligrams of iron?

5 mg

Step-by-step explanation:

Let

The excess in the consumption of iron is the difference between what she ate and what was recommended. Then, the appropriate algebraic operation is the subtraction.

y - x = 16 mg - 11 mg = 5 mg

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
