<span>Let x be Joanna's heart rate immediately after running one mile.
After this heart rate x decreased by 2 over 5, Joanna's heart rate was 60 beats per minute. We can set up an equation to solve this question.
x - (2/5) x = 60
(3/5) x = 60
x = (5/3) 60
x = 300 / 3
x = 100
Joanna's heart rate immediately after running one mile was 100 beats per minute.</span>
bro i read it wrong that's my bad hold on ill get the right one rq
x,x+2,x+4 the answer here is how i got it =x+x+2+x+4=180
=3x=174
=x=58
x=58
x+2=58+2=60
x+4=58+4=62
It would be -2x+3x=2, you combine like terms and divide. your answer should be 2, hope this helps
