2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like:
Second, regroup your terms. / Your problem should look like:
Third, add 4 to both sides. / Your problem should look like:
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:
Fifth, subtract r from both sides. / Your problem should look like:
Sixth, subtract 2r - r to get r. / Your problem should look like:

Answer:
r = 9
Answer: The answer is 7√3
Step-by-step explanation:
Since the hypotenuse is twice as long as the shortest leg and the triangle is 30°-60°-90°, therefore the shortest leg is 7 (not the answer to your question) and the other leg is 7√3. I hope this helps :)
Answer:
The innings pitched last season is 225.
Step-by-step explanation:
Given that,
Earned run average = 2.80
Allowed earned run = 70
The given equation is
![E=\dfrac{9R}{I}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B9R%7D%7BI%7D)
We need to calculate the innings pitched last season
Using given equation
![E=\dfrac{9R}{I}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B9R%7D%7BI%7D)
![I=\dfrac{9R}{E}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B9R%7D%7BE%7D)
Where, E = earned run
R = allowed earned run
I = innings pitch
Put the value into the formula
![I=\dfrac{9\times70}{2.80}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B9%5Ctimes70%7D%7B2.80%7D)
![I=225](https://tex.z-dn.net/?f=I%3D225)
Hence, The innings pitched last season is 225.
Its d. i took the k12 test.
d. The temperature steadily decreases before it levels off briefly. Then the temperature steadily decreases at a slower rate for the same amount of time as it decreased initially. After reaching its lowest temperature of the night, the temperature begins to steadily increase. When the temperature gets close to the same temperature it started at, the temperature levels off and remains the same.
34,669 to the nearest thousand is 35,000 because you look at the number to the right of that place value. less than 5, round down. 5 and up, round up.
