Write the direct variation equation If B= 6 when x = 2 , and find when x = 3

Answer 1

Find ratio

`\\ \sf\longmaosto (x)/(B)=(2)/(6)`

`\\ \sf\longmaosto (x)/(B)=(1)/(3)`

Put x=3

`\\ \sf\longmaosto (3)/(B)=(1)/(3)`

`\\ \sf\longmaosto B=3(3)`

`\\ \sf\longmaosto B=9`

Answer 2

B would equal 9

Explanation:

take 3/2 you get 1.5

multiple what b is now x 1.5

6*1.5 = 9
