Question

OOP I don't deserve to be in compact math LOL bc i need a lot of help.... w/ math

Answer 1

The answer is 152 grams of zinc

Answer 2

152 grams of zinc

Explanation:

You can always first create some ratios to clean it up

`(zinc)/(copper) = (4)/(19) = (x)/(722)`

x being zinc, what we need to find

Next we can cross multiply

`19x = (722)(4)`

`19x = 2888`

Lastly, we will divide both sides by 19 to get X alone.

`x = 152`
