Question

c varies directly as d, and c = 24 when d = 6. Find d when c = 36. 1
a. 1/4
b. 4
c. 6
d. 9

Answer 1

So scale factor

Answer 2

\[\frac{ 24 }{ 6 } = \frac{ 36 }{ x }\]

Answer 3

To solve this, you can cross multiple and set equal. 24x = 216, solve for x.

Answer 4

huh

Answer 5

The problem I set up is Proportions. if there is 24 of c, then there will be 6 of d.

Answer 6

so what do i do?

Answer 7

You would have c, which was 24, over d which was 6, but then since they say now that if c was to be 36, what would d be. so 36 over x

Answer 8

Any specific points you're curious on?

Answer 9

\[\frac{ 24 }{ 6 } = \frac{ 36 }{ }\]
