Asked by maham237 @ in Mathematics viewed by 399 People
What is the solution to 3/4(x + 8) > 1/2(2x + 10)?
A (–∞, –4)
B (–4, ∞)
C (–∞, 4)
D (4, ∞)
Answered by maham237 @
3/4(x + 8) > 1/2(2x + 10)
(3/4)x +(3/4)*8 > (1/2)*(2x)+(1/2)*10
(3/4)x +6 > x +5
(3/4)x - (3/4)x+6 > x-(3/4)x +5
6-5>(1/4)x +5-5
4*1>4*(1/4)x
4>x, or x<4
So, answer is C (–∞, 4).
