Plug in 6 for x in the equation:
f(6) = 3(6) - 5
Remember to follow PEMDAS. First, multiply
f(6) = 3(6) - 5
f(6) = 18 - 5
Finally, subtract
f(6) = 18 - 5
f(6) = 13
f(6) = 13 is your answer
hope this helps
Answer:
David's average speed is 55 mph and Andrew's average speed is 70 mph
Step-by-step explanation:
Let David's speed be s.
Average speed is given as:
speed = distance / time
They both spent the same time, t.
David's speed is:
s = 110 / t
=> t = 110 / s
Andrew travels 15 mph faster than David.
Andrew's speed is:
(15 + s) = 140 / t
=> t = 140 / (15 + s)
Therefore, since they spent the same time:
110 / s = 140 / (15 + s)
Cross multiply:
110(15 + s) = 140s
1650 + 110s = 140s
1650 = 140s - 110s
30s = 1650
s = 1650 / 30
s = 55 mph
Andrew's speed is:
15 + 55 = 70 mph
Therefore, David's average speed is 55 mph and Andrew's average speed is 70 mph.

8 1/2 as improper fraction is 17/2
You get that by multiplying the whole number 8 by the denominator of the fraction. That equals 16 and the 1 from the numerator of the fraction 1/2 so it looks like 16+1=17
This is your new numerator 17. Your denominator is 2 from the original fraction.
17/2
