nekit [7.7K]
If you change all the variables to the given valuables, the new equation would be (-3 + -9) - (-2 - 2 x -9)


Solve what's in the parenthesis first. -3 + -9 is -12. -2 x -9 is -18, and -2 - -18 is 16. Then you do -12 - 16 and you get -28

-28 is the answer :D

A person invested $420 in an account growing at a rate allowing the money to double
AURORKA [14]

Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t  log(2)

divide by log 2

1.19264508=  10 /t

10(1.19264508)

11.926450779=t
