Answer:
27 cm
Step-by-step explanation:
We usually use the distributive property because the two terms inside the parentheses can't be added because they're not like terms.
Make sure you apply the outside number to all of the terms inside the parentheses/brackets.
Answer:
Step-by-step explanation:
If given tables in the picture show the proportional relationship,
Number of wheels (w) ∝ Number of buses (b)
w ∝ b
w = kb
Here, k = proportionality constant
k = ![\frac{w}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Bw%7D%7Bb%7D)
Number of buses (b) Number wheels (w) Wheels per bus ![(\frac{w}{b})](https://tex.z-dn.net/?f=%28%5Cfrac%7Bw%7D%7Bb%7D%29)
5 30
8 48 ![\frac{48}{8}=6](https://tex.z-dn.net/?f=%5Cfrac%7B48%7D%7B8%7D%3D6)
10 60 ![\frac{60}{10}=6](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B10%7D%3D6)
15 90 ![\frac{90}{15}=6](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B15%7D%3D6)
Here, proportionality constant is 6.
Similarly, If number of wheels (w) ∝ Number of train cars (t)
w = kt
Here, k = proportionality constant
k = ![\frac{w}{t}](https://tex.z-dn.net/?f=%5Cfrac%7Bw%7D%7Bt%7D)
Number of train cars(t) Number of wheels(w) Wheels per train car (
)
20 184 ![\frac{184}{20}=9.2](https://tex.z-dn.net/?f=%5Cfrac%7B184%7D%7B20%7D%3D9.2)
30 264 ![\frac{264}{30}=8.8](https://tex.z-dn.net/?f=%5Cfrac%7B264%7D%7B30%7D%3D8.8)
40 344 ![\frac{344}{40}=8.6](https://tex.z-dn.net/?f=%5Cfrac%7B344%7D%7B40%7D%3D8.6)
50 424 ![\frac{424}{50}=8.48](https://tex.z-dn.net/?f=%5Cfrac%7B424%7D%7B50%7D%3D8.48)
Since, ratio of w and t is not constant, relation between number of wheels and number of train cars is not proportional.

Answer:
D*1.2 (OR) 1.2D
Step-by-step explanation:
Because the new menu has one hundred percent of the original menu (D), plus twenty percent, the new menu is 120%, or 1.2
You can then multiply the number of items on the original menu (D), by the new menu's value, which is 1.2 (or 120%).
This brings you to the answer of 1.2D
