How many ounces of gold are in aa 1414-karat gold chain that weighs 2.82.8 ounces?

As per the gold standard, the purest form of gold will have 24 karats.

The given chain has 14 karat gold.

Therefore, the percentage of pure gold = 14/24  =  0.5833 or 58.33%

If the total chain weighs 2.8 ounces, then the total weight if gold in the chain = 0.5833*2.8 ounces (since the % of pure gold is only 58.33%)

The total weight if gold in the chain = 0.5833*2.8 = 1.633... = 1.63 ounces (Rounded to two decimal places)

step-by-step explanation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
