Laila took five math tests, each worth a maximum of 100100 points. Laila's score on each test was an integer between 00 and 100100, inclusive. Laila received the same score on the first four tests, and she received a higher score on the last test. Her average score on the five tests was 8282. How many values are possible for Laila's score on the last test

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
