Let x = John's age now
half of what johns age was 4 years ago: (1/2)(x-4)
is equal to one third of what it will be in 5 years time: (1/3)(x+5)
(1/2)(x-4) = (1/3)(x+5)
3(x-4) = 2(x+5)
3x - 12 = 2x + 10
Answer:
B) 6

Thank you.
Answer:
2) (0,-3)
Step-by-step explanation:
hello :
put x=0 and y= -3 in this system !
Y = 3/4x - 3
3x - 4y = 12
- 3 = 3/4(0) - 3 means : -3 = -3 ......true
3(0) - 4(-3) = 12 means : 12= 12 ......true
Yo sup??
We can solve this problem by applying trigonometric ratios.
sin36=XY/WY
WY=5/sin36
=8.5
Hope this helps.
