Answer:
2
Step-by-step explanation:
The answer is this: $3.60
4 x 10 = 40 - 0.4 = 3.6
Answer:
x = 15
Step-by-step explanation:
3x / 3 = 45 / 3 x = 15
Okay so i would do this with a logarithm.
5^(2x) = 28
take the log of both sides
log5^(2x) = log28 and because of this log rule: logA^n = nlogA
(2x)log5= log28
then divide by log5 on both sides
2x = log28 / log5
and divide by 2
x = (log28 / log5) /2
this can be found with a calculator:
x= about 1.03521...
round that to whatever the question says to
