Answer:
x(x)=1/4(30+60+x)
Step-by-step explanation:
minutes spent on math homework= x
minutes spent on history homework= 30 min
minutes spent on English homework= 60 min
Total minutes spent on homework = x+30 +60
Also
x= 1/4(x+30 +60)
x= x/4 + 90/4
x-x/4= 90/4
(4x-x)/4=90/4
3x=90
x=30
Hence time spent on maths=30 min
total time spent= 30+60+30
= 120 min
1/4 of 120 min= 30 mins!
