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.
Daniel [21]

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

In a certain Algebra 2 class of 28 students, 14 of them play basketball and 19 of them
erastova [34]

Answer:

13/28

Step-by-step explanation:

Total number of students = 28

Number of students that play basketball = 14

Number of students that play baseball = 19

Number that play neither sport = 5

Number of students playing sports = 28 – 5 = 23

Number of students playing both basketball and baseball = 14 + 19 – 23 = 10

Number of students that play only basketball = 14 – 10 = 4

Number of students that play only baseball = 19 – 10 = 9

Number of students playing basketball or baseball = 4 + 9 = 13

P(a student chosen at random plays basketball or baseball) = 13/28
