Is there a story that goes with the question.
Answer:
13/30=m
Step-by-step explanation:
if 2/5 +m=5/6 than 2/5-5/6=-m
step 1 find a common detonator which would be 30
12/30-25/30=-m
-13/30=-m
now take away the negative both sides
13/30=m
Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.
In oyur case,
Solve this equation to find x:
Answer: 6, choice B.
Answer:
the ones you can use are A,B and E
Step-by-step explanation:
Plug each one in and find out if it works or not
Train a speed = x+15
Train b speed =x
255/x = 300/(x+15)
255(x+15) = 300x
255x +3825 =300x
3825 = 45x
X = 3825/45 =85
<span>Train B = 85 miles
per hour</span>
<span> Train A = 85+15 = 100
miles per hour</span>
