An adult takes tablets containing 24 milligrams of zinc. if the amount is 160% of the recommended daily allowance, how many milligrams are recommended?

You would need to set of a ratio/proportion.

160/100 =24/x

you can reduce and make it to 8/5 = 24/x

the cross multiply 8x = 5(24)

so now it becomes 8x = 120

then we get the variable by itself by dividing by 8 on both sides, x = 120/8

so x=15, meaning 15 milligrams are recommended

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
