Answer:
when x = 7, y = 21
Step-by-step explanation:
This is about direct variation. If y varies directly with x, then there is a constant factor of variation, k. The constant of variation can be found by ʸ⁄ₓ
k = ʸ⁄ₓ
k = ¹⁵⁄₅ = 3
Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.
y = 3x
y = 3(7)
y = 21
Answer:
i believe itd be 66 dollars :D
hope this helps !!
Step-by-step explanation:
x - 18 = 48
add 48 and 18 and get the answer = $66
The answer is 13.
Because this is a kite, the diagonals intersect perpendicularly or with a 90° angle.
In the triangle DIC, which is a right triangle, the legs are 5 and 12. To find the hypotenuse, we use Pythogarean theorem:

Plug in the givens:

Take the squares:

Take the square root of both sides:

We find the line segment DC. In the question it says "BD = DC". So BD is equal to 13.
