Answer:
BD = 78
x = 7
Step-by-step explanation:
As we can see, BC plus CD will be equal to BD. That means we can set up the equation 6x+15+3x = 10x+8. First, we combine like terms to get 9x+15 = 10x+8. Then we can subtract 9x from both sides, to get 15 = x+8. We then subtract 8 from both sides to get x = 7. Since x = 7, we can plug in x for the equation given for BD, 10(7)+8. This will come out to 78.
The answer is: D) 115
The explanation is shown below:
1. You have that the frequency with which a cricket chirps varies directly with the temperature, which you can express it as following:
Where is the frequency with which a cricket chirps, is the temperature and is the constant of proportionality.
2. If the cricket chirps 100 times per minute in 80° weather, you can calculate as below:
3. Therefore, the frequency in 92° weather is:
I think it’s just asking you to add the two functions (f + g)(x)
If f(x) = sqrt x + 3
And g(x) = x + 2
Then (f + g)(x) = (sqrt x + 3) + (x +2)
And I’m pretty sure that’s all you can simplify
