Art had $415.75 in his account at the beginning of the month. he wrote checks for $134.16, $78.90, and $15.67. how much must he transfer from his savings to cover a rent check for $250?

62.98

Step-by-step explanation:

Since he has 415.75 in his account, and wrote checks to take out money, we can say his current balance is 415.75-134.16-78.9-15.67, which gives us 187.02. Thus, 250-187.02=62.98, which is our answer!

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

for future students the answer is b
