Answer:
6 miles
Step-by-step explanation:
From the above question:
Stan ran 4 and StartFraction 7 Over 10 EndFraction miles
The number of miles stan ran =
4 7/10 miles
We are also told that this number of miles was 1 and StartFraction 3 Over 10 EndFraction fewer miles than Matt ran.
Let the number of miles Matt ran = m
Hence,
4 7/10 miles = m - 1 3/10
m = 4 7/10 + 1 3/10
m = (4 + 1) + ( 7/10 + 3/10)
m = 5 + (7 + 3/10)
m = 5 + (10/10)
m = 5 + 1
m = 6 miles
Therefore, the number rod miles Matt ran was 6 miles
In this question, you're solving for a.
Solve for a:
-84 = 6(4a - 2)
<em>Distribute the 6 to the variables inside the parenthesis</em>
-84 = 24a - 12
<em>Add 12 to both sides</em>
-72 = 24a
<em>Divide both sides by 24</em>
-3 = a
This means that answer choice D would be the correct answer.
Answer:
D). -3
Here, the distance traveled is not given, but Irina's bike-riding speed is: it is 16 mph.
Let the distance traveled be d. Then d = (27 mph)(0.4 hr) = 10.8 miles.
By bicycle, distance = rate times time. Here, 10.8 miles = (16 mph)(time), and so
10.8 mi
time = --------------- = 0.675 hour (40.5 minutes).
16 mph
The dollar amount of the discount is 440 - 154 = $286.
