Step-by-step explanation:

The equation of a line is y-mx+b with m being slope and b being y-intercept. Using the values provided in your problem, your answer would be y=2/3x+9, or C.
Distance hiked by Sara last week = 8 miles
Distance hiked by Sara on Monday this week = 3 miles
<span>Distance hiked by Sara on Tuesday this week = 4 miles
</span><span>Distance hiked by Sara on Thursday this week = 3 miles
</span>So
Total distance hiked by Sara this week = (3 + 4 + 3) miles
= 10 miles
The number of more miles hiked by Sara this week = (10 - 8) miles
= 2 miles

Amplifiers : Time Taken in minutes
5 : 30
5x= 125
x= 25
so
5*25 : 30*25
125 : 750
750 minutes.
12 hours 30 minutes.
I see you're probably trying to use a math editor to present this problem. Unfortunately, I'm unsure how to decipher your "-\frac {a }{8.06)." What fraction are you speaking of?
Given "<span>#-\frac { a } { 8.06} + 7.02= 18.4#," all I can say with certainty is that you could legitimately subtract 7.02 from both sides:
</span><span>#-\frac { a } { 8.06} + 7.02= 18.4#
- 7.02 = -7.02
After I've heard back from you, I'll try to help you solve the entire problem.
