The value of nth term is calculated by the equation,
an = (a1) x r^(n - 1)
Using this equation to find for the common ratio,
-8192 = 8 x r^(6 - 1)
The value or r is -4. Using the same equation to find for the 12th term,
a12 = 8 x (-4)^(12 - 1)
a12 = -33554432
Let the number of weeks to have same amount = x Then:-
1200 + 40x = 700 + 50x
1200 - 700 = 50x - 40x
10x = 500
x = 50
answer is 50 weeks
Answer:
3x
Step-by-step explanation:
-(x-1) +5 = 2(x+3) - c
C is the unknown term
Distribute the negative sign and the 2
-x+1 +5 = 2x+6 -c
Combine like terms
-x+6 = 2x +6-c
Solve for c
Add x to each side
-x+x +6 = 2x+x +6-c
6 = 3x+6 -c
Add c to each side
6+c = 3x +6 -c+c
c+6 = 3x+6
Subtract 6 from each side
c+6-6 = 3x+6-6
c = 3x
When c = 3x, the two sides of the equation are equal, and the solutions are infinite.

Answer:
y=11
Step-by-step explanation:
1.) isolate the variable and coeffient by subtracting 10 from both sides to get 22=2y
2.) do the inverse operations to get y by itself so 22 divided by 2 which equals 11
3.) y=11
