Answer:
11x+7
Step-by-step explanation:
This is because, in order to simplify, first you need to distribute the 2 into the x+5. So, you get 2x+10. Then you get 9x-3+2x+10. The 9x and 2x combine to get 11x. The -3+10 combine to get 7. So you have 11x+7.
Answer:
1 hour and 6 minutes
Step-by-step explanation:
- A temperature difference of 58-40 = 18°F was obtained in 2 hours
- A temperature difference of 68-40 = 28°F will be obtained in x hours
The next proportion must be satisfied:
18 °F / 28 °F = 2 hours / x hours
x = 2*28/18
x = 3.1 hours in total
Given that she has already waited 2 hours, she must wait 3.1 - 2 = 1.1 extra hours. 1 hour is equivalent to 60 minutes, then 0.1 hours is equivalent to 0.1*60 = 6 minutes.
