Answer:
Step-by-step explanation:
2(4x - 8) - 10
8x - 16 - 10
|_______|
8x - 26
-5x + 8 - 11x - 12
___ ___ _____ ____
___ ____
-16x - 4
-3(4x - 5)
-12x + 15
For the third and first exercises, you just use the Distributive Property, and for the second exercise, all you are doing is combining like-terms.

Step-by-step explanation:
sum of the arithmetic sequence
a1 = 8
a2 = a1 + 8 = 8+8 = 16
...
an = 8×n
the sum of the first n elements of such a series is
n/2 × (2×a1 + (n - 1)×d]
with d being the difference between 2 consecutive elements (= the added constant).
so,
s30 = 30/2 × (2×8 + 29×8) = 15×(31×8) = 3720
Answer:
Step-by-step explanation:
Angle E is (7x+27) because it is corresponding.
So, 7x+27+15x-5=180 (angle on a straight line is 180 degrees
22x+22=180
22x=158
x= 158/22 = 7.18'
Answer:
5 and -3
