A park ranger hiked 3/4 mi to a lookout, another 5/7 mi to a bird's nest, and finally 5/14 mi to a campsite. How far did the par
dusya [7]

Answer:

2 miles and 88 yards.

Step-by-step explanation:

4 has 2*2 as prime factors

5 is prime

10 has 2 and 5 as prime factors

Thus, the lowest common denominator will be 2*2*5

3/4=15/20

3/5=12/20

7/10=14/20

Now that we have three fractions with the same denominator, we can add the numerators

15+12+14=41

So 41/20ths

That’s 2 and 1/20th

So the final answer is 2 miles and 88 yards! :)

J and M are base angles of isosceles trapezoid JKLM. If mJ = 20x + 9, and mM = 14x + 15, find mK.
Rainbow [258]
20x + 9 = 14x + 15 
<span>6x = 6 </span>
<span>x = 1 </span>

<span> So base angles are 20 + 9 means 29 degrees. To calculate the m of  angle k, subtract 29 from 180: </span>

<span>180 - 29 = 151 degrees.
hope it helps</span>
