PLZ HELP ME THIS IS SO CONFUSING AND I DON'T UNDERSTAND ANYTHING PLZZ HELP! PLZ REPORT CARDS ARE TOMMROW An expression is given -2y + 3/2 x + 7/4

Which are equivalent to the given expression? Select each correct answer. And Explain?(FIRST IMAGE)

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
