The combined mass of 100 nickels is 500,000 milligrams. What is the mass of each nickel?

5 grams = 500 centigrams = 5000 milligrams = 5000000 micrograms

Step-by-step explanation:

So the only correct answer in your choices is the third option, 5000 milligrams.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
