Answer 1

Step-by-step explanation:

6. 5m=60. (10,5,12,15)

if m=10, 5(10)=60

=>50≠60

m =10 doesnot satisfy

if m=15, 5(5)=60

25≠60

m =5 doesnot satisfy

if m=12, 5(12)=60

=>60=60

m =12 is satisfies

if m=15, 5(15)=60

=>75≠60

m =15 doesnot satisfy

7. 3n+7=22

if n=5,. 3(5)+7=22

=>15+7=22

=>22=22

8. x+4=11

=>7+4=11

=>11=11

therefore,x=7

9. (a),(b),(d)
