Answer:
-1/7
Step-by-step explanation:
The first step is to isolate the variable, x. To do so, add x to both sides. This gives you the new equation: 2 + 7x = 1.
Now, subtract 2 from both sides to further isolate the variable, giving you 7x = -1.
Divide both sides by 7, giving you the final equation of x = -1/7.
Call the radius r and the height of the cone h. The formula for the volume of a cone is r^2*h*pi/3, and the formula for the volume of a sphere is 4r^3/3, so half of a sphere has volume 2r^3/3. Adding these, our answer is:
Answer:
X= - 5
Step-by-step explanation:
Answer: 1 27
2. 54
9 243
10. 270
Step-by-step explanation: for one batch, the total minutes will be 15 + 12, so 27. Multiply 27 times b, the number of batches.
There may be another solution IF he is starting to prepare the next batch while the preceding is in the oven. Since this is not stated, I won't offer that solution here.
