It's B.) The student’s answer is not reasonable. Estimation: 170 + 90 = 260

The answer is B because if you round to the nearest 10, B would be the answer. C is not correct because 93 rounded to the nearest 5 (like 175) is not 100. A is not correct because the estimation is not reasonable. D is also not correct because you would need to add the numbers, not subtract.

X + (x+1) = 2x+1
Here, 2x+1 is always odd
For example the value of x is 2 then we can say that,
x=2; x+1=3; 2x+1 = 5 <u>[odd number(5)]</u>
= 2 + 3 = 5

Write the expression as the sine or cosine of an angle sin(pi/7) cos(x) + cos(pi/7) sin(x)

Natasha_Volkova [10]

Answer:

$\sin(\frac{\pi}{7}+x)$

Step-by-step explanation:

We are going to use the identity

$\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)$

because this identities right hand side matches your expression where

$a=\frac{\pi}{7}$ and $b=x$ .

So we have that $\sin(\frac{\pi}{7})\cos(x)+\cos(\frac{\pi}{7})\sin(x)$ is equal to $\sin(\frac{\pi}{7}+x)$ .
