Answer:
5
alternates
Step-by-step explanation:
The series is for k = 0 to 4, so k = 0, 1, 2, 3, 4.
That is 5 terms.
-1/2 is inside the parentheses and is raised to 0, 1, 2, 3, 4.
A negative number raised to an even integer is positive.
A negative number raised to an odd integer is negative.
The sign of each term in the series alternates.
Mike is 29.
5+2x+x=41
5+3x=41
3x=36
x=12
5+2x=Mike’s Age
5+2(12)= Mike’s Age
29= Mike’s Age
30x - 20 = 50
use inverse operations to isolate x
30x - 20 = 50
+ 20 +20
30x = 70
(30x = 70) /30
x= 7/3 (this is the simplified term)
