Sin (x/2)= √2- sin (x/2) solve for the exact solutions in the interval (0, 2π)
serg [7]

sin\left( \frac{x}{2} \right)=\sqrt{2}-sin\left( \frac{x}{2} \right)\implies sin\left( \frac{x}{2} \right)+sin\left( \frac{x}{2} \right)=\sqrt{2}\implies 2sin\left( \frac{x}{2} \right)=\sqrt{2} \\\\\\ sin\left( \cfrac{x}{2} \right)=\cfrac{\sqrt{2}}{2}\implies sin^{-1}\left[ sin\left( \cfrac{x}{2} \right) \right]=sin^{-1}\left( \cfrac{\sqrt{2}}{2} \right) \implies \cfrac{x}{2}= \begin{cases} \frac{\pi }{4}\\\\ \frac{3\pi }{4} \end{cases} \\\\[-0.35em] ~\dotfill

\cfrac{x}{2}=\cfrac{\pi }{4}\implies \boxed{x=\cfrac{\pi }{2}}~\hfill \cfrac{x}{2}=\cfrac{3\pi }{4}\implies \boxed{x=\cfrac{3\pi }{2}}

The equation 3x + 6 = 12 involves two operations performed on x: multiplication by 3 followed by addition of 6. What operations
BlackZzzverrR [31]
3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

\frac{3x}{3} = \frac{6}{3}
3 and 3 cancels out
x = 2

Please help with step one and two.​
Nikitich [7]

Please keep in mind that the answers may not be correct. I have tried my best to answer.

1. 83.333...% would fit. We must first solve for x. As you can see, we have a similarity in the picture. 16 and 4. It's 4. So, we multiply that by 6 which equal 24=x. Now, we know that space (Not provided) is 4. So, we just divide 20 by 4. It will equal 5, add the space not provided and becomes 6. All you gotta do is now divide 100/6. 16.666... Multiply by 5 since that is how much it is providing. Then, your answer will be 83.333...%

2. 88.888...% would fit. Like the above, we must solve for x. As you can tell, the situation is similar to the original. Divide 18 by 4, 4.5. Multiply 6 by 4.5, 27. Subtract 27 by 24, 3. Now we know that the space (not provided) is 3. Divide 24" by 3, 8. Add 1 due to the non provided space. 9. Divide 9 by 100, 11.111... Multiply by 8 and get the answer. 88.888...%

A frozen pizza is stored in a grocery store's freezer at - 6°C. During its transport home, its temperature rises 13°C. When the
Rasek [7]
At the start pizza has -6
the temperature rises 13 during the transport, so it should have -6+13=7
because the temperature goes down 19 when pizza is put in the home freezer, the final temperature should be 7-19=-12
so b is the correct answer
if the temperature rises -> +
if the temperature goes down -> -
