Given that y varies directly as x and y = 18 when x = 6

Find the value of y when x=5
find the value of x when y=30

  y = 15,    x = 10

Step-by-step explanation:

NOTE: "varies directly" is of the form      where k is the constant of proportionality.

First, input the given x and y-values to find k

Next, input the given value and k = 3 to solve for the missing variable.

true

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.
