Answer:
27x-68
Step-by-step explanation:
-4(2x+3)+7(5x-8)
= -8x-12+35x-56
=27x-68
Answer: k = 76 degrees
Step-by-step explanation:
A linear pair of angles are always supplementary. (They sum to 180)
If the pair of angles are k and 104, they have to add up to equal 180.
180-104= 76
K has to equal 76 degrees
Answer:
The first one can be simplified, but the second one cannot be (that i know of). The first one simplified would be 9 to the power of 8.
Step-by-step explanation:
Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
Equation: 80 - 6.75x = 19.25
Sandwiches: 9
(x=9)
