→ Here,
- y varies directly as x means that y = kx
- here value of (k) is not known
by substituting the values of x and y, y = 18 when x = 12
![\rm{y = kx} \\ \\ \rm{18 = 12k} \\ \\ \rm{k = \cancel \frac{18}{12} } \\ \\ \rm{ k = 1.5}](https://tex.z-dn.net/?f=%5Crm%7By%20%3D%20kx%7D%20%5C%5C%20%20%5C%5C%20%20%5Crm%7B18%20%3D%2012k%7D%20%5C%5C%20%20%5C%5C%20%5Crm%7Bk%20%3D%20%20%5Ccancel%20%5Cfrac%7B18%7D%7B12%7D%20%7D%20%5C%5C%20%20%5C%5C%20%20%5Crm%7B%20k%20%3D%201.5%7D)
Now, substituting value of k nd x in y = kx

2/3 ⇒ 8/12
5/6 ⇒ 10/12
Hope that is what you were looking for :)
Check the picture below
the angle is in degrees, thus, when taking the sine, make sure your calculator is in Degree mode
3.24, 500=53*(2)^t, simplify it to get the answer
Is this for area and perimeter? If so, first make the fraction a decimal, (that would be 3.5). Then, for permeter, add 3.5 + 3.5 + 9 + 9, which is 25, for area, multiply 3.5 by 9, which is 31.5. Hope this helped!
