PLEASE HELP IM STRUGGLING SO BAD AT MATH please help :((

Answers

Step-by-step explanation:

1.

Plug in the values for 48-4t

t= 0

48-4(0) = 48-0 = 48

t=2

48-4(2) = 48-8=40

t=4

48-4(4) = 48-16 = 32

t= 6

48-4(6) = 48-24 =24

t=8

48-4(8) = 48-32 = 16

48 40 32 24 16 is our answer

To find when the output is 0, that means that 48-4t must be equal to 0, so

48-4t=0

subtract 4t from both sides

48=4t

divide both sides by 4

12=t

Nico and Lorena used different methods to determine the product of three fractions.

Nico’s Method
Lorena’s Method
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over 30 EndFraction = Negative StartFraction 4 over 15 EndFraction
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over Negative 30 EndFraction = StartFraction 4 over 15 EndFraction

Whose solution is correct and why?
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction.
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction.
