Question

If "u" varies directly with "v," and u = 6
when v = -7, what is "u" when v = 4

Answer 1

9514 1404 393

Answer:

u = -3 3/7

Explanation:

The new value of v is 4/-7 = -4/7 of the old value. Because u varies directly, its new value will also be -4/7 of the old value.

u = -4/7(6) = -24/7

u = -3 3/7
