If x varies directly as y, and x=24 when y=8, find x when y=10

when y= 10 x=30

How is it x= 30 you may ask?

x varies directly as y. This means that:

(x/y) is a constant. Let us call this constant as "k". i.e: x/y=k

for the first one which is x=24 y= 8

24/8= 3

BUT... about y=10?

for y= 10 its the same rule x/y= k in this case we already found K which is 3

*we don't have x so we cant divide anything however we do have  "k" and y so all we have to is multiply so its 10*3= 30*

And that's how x= 30 when y= 10

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
