Answer is 4.
Right angle= 90
50+ 10(4)= 90
If you reduce the 5 for 20, you will get 1 for $4. Therefore, 12×4 will be the answer ($48)
The answer for the question shown above is the first option, which is:
- Direct.
The explanation is shown below:
1. The problem says that <span>The number of tons of coal varies as the number of hours.
2. Therefore, you can write the following equation:
number of tons:x
number of hours:y
x=ky
Where k is the constant of variation.
3. Therere the variation is direct.</span>
Answer:
x = 9.6
