do I multiply or divide?

anonymous · Answer

cross muiltiply that :]

anonymous · Answer

3x + 2x = 250
5x = 250
x = 50

so 3x  = 150 minutes on aerobics
and 2x = 100 minutes on weight training

anonymous · Answer

It is not 3/2 = 250/x that would be if it said she spent 250 minutes doing aerobics

anonymous · Answer
