Right triangles have a 90 degree corner.
Reading - 44
Sports - 55
Video games - 55
Music - 66
--------------------------
= 220
Reading = (44/220) x 100 = 20%
Sports = (55/220) x 100 = 25%
Video games -> same as sports
Music = (66/220) x 100 = 30%
20 + 25 + 25 + 30 = 100%
hope this helps :)
plz let me know if this was not your question
110 - 4x = x + 10
100 = 5x
x = 20
2x - 20 = 3y - 10
Plug in x
2(20) - 20 = 3y - 10
40 - 20 = 3y - 10
20 = 3y - 10
30 = 3y
y = 10
