Question

please solve it. Question is Complete the following tables assumingthat x is.in direct variation with y​

Answer 1

in direct proportion, x 1/ x 2 = y 2/ y 1

so , let's take the unknown number as x.

x / 3.5 = 9/4.5

x/ 3.5 = 1/0.5

x = 1/ 0.5 × 3.5

x = 7

ii) 9/4.5 = x/ 6.5

1/0.5×6.5 = x

13 = x

iii) 9/4.5 = 15 / x

1/0.5 = 15/x

x = 0.5/1 ×15

x = 7.5

iv) 9/4.5 = x/ 9.25

1/0.5×9.25 = x

18.5 = x

v) 9/4.5 = 26.5/x

1/0.5 = 26.5/x

x = 26.5×0.5/1

x = 13.25

hope it may help you.
