Answer:
B. 6 < n < 25
Step-by-step explanation:
We are given the triangles WXY and WZY with sides XY and ZY congruent and equal to 8.
As the sides WX = 11 > WZ = 9.
Then, the angles opposite to WX will be greater than the angle opposite to WZ.
i.e. ∠WYX > ∠WYZ
i.e. (7n+5)° > 47°
i.e. 7n° > 42°
i.e. n > °
i.e. n > 6°
Since in ΔWXY, the sum of all three angles is 180°.
This means that (7n+5)° < 180°
i.e. 7n < 175°
i.e. n < °
i.e. n < 25°
Hence, we get that the range of n is 6 < n < 25.

Answer:
x = -1
Step-by-step explanation:
combine like terms on both sides (like terms refers to the variable, x in this case) so
3x + 7 = 11x + 15
then get x terms to one side and non-x terms to the other
this gives you: 7 - 15 = 11x - 3x
-8 = 8x
dived both sides by 8 (since its the constant with x) which gives you
x = -1
hope I could help ( I messed up at first but I fixed it)
Answer:
976.80
Step-by-step explanation:
880 times 0.11 to find amount that it increased by added to the amount it was gives you 976.80
