Step-by-step explanation:
Direct variation has this equation:
y = kx
where k is the constant of variation
y = -5 ; x = -15
y = kx
-5 = k(-15)
-5/-15 = k
1/3 = k
Choice D. y = 1/3 x

Answer:
Jhon
Step-by-step explanation:
At the rate of 4 minutes per problem, it take Juaqine ...
(4 min/prob)×(6 prob) = 24 min
to solve the problems.
That is more time than it takes Jhon, so Jhon is faster.
If there are 15 boards there are 14 gaps in-between.
But first, 15 boards each 9 and 1/4th inches so you get a total of 138 inches and 3/4th
If you subtract that from 144 you get 5 inches and 1/4th. The remaining amount is the total of all of the distance from the spacing.
Then you divide that by 14 (number of gaps/spacing in-between.)
So you get .375 inches. (3/8)
So width of the spacing between each board is 3/8ths of a inch
