Question

Diego collected x kg of recycling. Lin collected 2/5 more than that. [ Select ] Lin biked x km. Diego biked 3/10 less than that. y = 10/3x Diego read for x minutes. Lin read 4/7 of that. y = 7/4x

Answer 1

I assume you want to mathematically represent the above

Answer and explanation:

If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:

Diego = x

Lin = x +2/5 of x= x+2/5x

if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:

Lin=x

Diego= x-3/10 of x= x-3/10x

If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:

Diego=x

Lin =4/7 of x = 4/7x
