VERY IMPORTANT QUESTION PLEASE SOLVE IT;(:(:(

1)20

2)55

3)35

4)math=15, English=20

5)shown above

Step-by-step explanation:

1) add 15 students who like math only and 20 liked English only and 5 who did not like any subjects

15+20+5=40

subtract by total class of 60 students

60-40=20 students to like both subjects

2) add 15 students who like math only, 20 students who like English only and 20 students who like both subjects

15+20+20=55 students to like at least one subject

3) add 15 students who like math only and 20 students who like English only

15+20=35 students to like only one subject

4) as shown in Venn diagram

math=15 students, English=20 students

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
