Change the denominators to be the same:

Simplify each fraction:

Add the fraction in the bracket:

Multiply:
Answer: 3:1 or 3 to 1
The ratio tripled is 18:6 or 18 to 6
Simplified it is 3:1 or 3 to 1
A=p(1+i/k)^kn
24000=p(1+0.064/4)^4*15/12
24000=p(1.016)^5
P=24000/(1.016)^5
P=22,168.83
Since the lines are parallel their slopes are equal. So, the equation is y=4x+b
Now we need to find the y-intercept, which is b.
Now, Plug in point p to find b:
3=4*(-1)+b
b=3+4=7
The equation is: y=4x+7
