Step-by-step explanation:
6x-11+8x-29+3x-1= 180
17x-41= 180
17x = 139
x= 8.17
m<K = 36.4°
Answer: warmer to the cooler
Step-by-step explanation :Conduction is the movement of heat through a substance by the collision of molecules. ... The slower molecules gain more thermal energy and collide with other molecules in the cooler object.
= 1455
generate a few terms of the sequence using 
= 3n + 2
= ( 3 × 1) + 2 = 5
= (3 × 2) + 2 = 8
= (3 × 3 ) + 2 = 11
= (3 × 4 ) + 2 = 14
= ( 3 × 5 ) + 2 = 17
the terms are 5, 8, 11, 14, 17
these are the terms of an arithmetic sequence
sum to n terms is calculated using 
= 
[ 2a + (n-1)d]
where a is the first term and d the common difference
d = 8 - 5 = 11 - 8 = 14 - 11 = 3 and = 5
= 
[( 2 × 5) + (29 × 3) ]
= 15( 10 + 87) = 15 × 97 = 1455
The answer is 22220. just add all the numbers together
