Ted practices two types of swimming styles for a total of 50 minutes every day. he practised the breaststroke 20 minutes more than he practices the butterfly stroke.

part a: write a pair of linear equations to show the relationship between the number of minutes ted practices the butterfly stroke every day (x) and the number of minutes he practised the breaststroke every day (y). (5 points)

part b: how much time does ted spend on practising the breaststroke every day? (3 points)

part c: is it possible for ted to have spent 45 minutes practising the butterfly stroke every day? explain your reasoning. (2

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

its an acute right triangle
