Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x
![\frac{x}{3x} \times 120 \\ =40](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3x%7D%20%20%5Ctimes%20120%20%5C%5C%20%3D40)
![\frac{2x}{3x} \times 120 \\= 80](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B3x%7D%20%20%5Ctimes%20120%20%5C%5C%3D%2080)
40 and 80 are in the ratio 1:2 of 120.
Hope it helps!!!

Answer:
t(d(n)) = 12n + 7
Step-by-step explanation:
- t(d) = 3d + 1
- d(n) = 4n + 2
<u>t(d(n)) = t(4n + 2) </u>
Substitute the function d(n) into the function t(d) for the variable d.
t(4n + 2) = 3(4n + 2) + 1
t(d(n)) = 12n + 7
