DEC=72 degrees. The two angles equal each other so you much set them to equal each other.
Hello there!
Answer: C
Step-by-step explanation:
C) -2 + 2 = 2 + (-2)
Why?
Well, we know that when we have a negative sign and a positive sign, we ended up having negative.
Thus, 2 + (-2) = +2 - 2 which is the inverse of the other side.
I hope this answer helps you. As always, it is my pleasure to help students like you!
The answer is 4+8+16+32+64+128+256+512+1024: This is equivalent to 2044
You're looking for an inequality of the form
, or
, or
.
Start with
![350^\circ\le t\le400^\circ](https://tex.z-dn.net/?f=350%5E%5Ccirc%5Cle%20t%5Cle400%5E%5Ccirc)
Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get
![-25^\circ\le t-375^\circ\le25^\circ](https://tex.z-dn.net/?f=-25%5E%5Ccirc%5Cle%20t-375%5E%5Ccirc%5Cle25%5E%5Ccirc)
so we can set
and
, and we can rewrite this inequality in terms of absolute values as
![|t-375^\circ|\le25^\circ](https://tex.z-dn.net/?f=%7Ct-375%5E%5Ccirc%7C%5Cle25%5E%5Ccirc)
