Answer:
x=1
Step-by-step explanation:
3/2+1/2x=2x
Multiply each side by 2 to get rid of the fractions
2(3/2+1/2x)=2x*2
3+x = 4x
Subtract x from each side
3+x-x = 4x-x
3 = 3x
Divide each side by 3
3/3 = 3x/3
1 =x
Answer:
<u>Sum of n terms of a GP:</u>
#1
- a₁ = 5
- r = 2
- n = 9
- S₉ = 5(2⁹ - 1)/(2 - 1) = 5(511) = 2555
Correct choice is C
-----------------------------
#2
- a₁ = 12
- r = 1/2
- n = 5
- S₅ = 12(1 - (1/2)⁵)/(1 - 1/2) = 12(31/32)/(1/2) = 23.25
Correct choice is A
