Part A
(85 km)/(51 min) = (x km)/(60 min)
85/51 = x/60
85*60 = 51x
5100 = 51x
51x = 5100
x = 5100/51
x = 100
<h3>Answer: 100 km</h3>
=====================================================
Part B
510 m = 0.510 km
(85 km)/(51 min) = (0.510 km)/(x min)
85/51 = 0.510/x
85x = 51*0.510
85x = 26.01
x = 26.01/85
x = 0.306
This represents the number of minutes. Multiply by 60 to get the number of seconds
0.306 min = 0.306*60 = 18.36
<h3>Answer: 18.36 seconds</h3>

Answer: 1320 (choice C)</h3>
Explanation:
There are 12 choices for left field.
Then there are 12-1 = 11 choices for right field.
Lastly, there are 11-1 = 10 choices for center field.
In total we have 12*11*10 = 1320 different permutations or orderings.
Answer: Can you take a more clear picture
Step-by-step explanation:
<span>When two lines are crossed by a transversal, the lines are </span>parallel if <span>the </span>Alternate Interior Angles are equal<span>.
</span><span>Alternate Interior Angles in the diagram are 1 and 5; 4 and 8; 2 and 6 and 3 and 7.
If lines a and b are parallel, then angle 1 must equal angle 5.
If that's the case then </span><span>2x+30 equals 5x ‒ 45
</span><span>Solving 2x+30 = 5x ‒ 45
3x = 75
x = 25
So, when x = 25, the lines are parallel.
