Answer: k = 2x
Step-by-step explanation:
x2 = k
Swap sides so that all variable terms are on the left hand side.
k=x
2
Answer:
x = log 10/log 3
Step-by-step explanation:
3^x - 4 = 6
3^x = 10
We take log base 3 of both sides since log_3 3^x is simply x.
log_3 3^x = log_3 10
x = log_3 10
We have an answer for x, but it is a log base 3. We want log base 10.
Now we use the change of base formula.
log_b y = log y/log b
x = log 10/log 3
well if you know the unit rates
12 mph=Terrance
8 mph=Jesse
so to find Sandra just simplify
(8*60)/(45*1)(miles/hour
= (480/45)mph)
so 10 2/3 miles per hour
