Trains A and B left stations R and S simultaneously on two separate parallel rail tracks that are 350 miles long. The trains pass each other at point X after traveling for a certain amount of time. Up to point X, the average speed of train B was 25% less than the average speed of train A. How many miles of the rail tracks has train A traveled when the two trains passed each other?

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
