4/6 is equivalent to 2/3. Both the numerator and the denominator is divisible by three, so you divide each by three. that gives you 2/3.
I believe his brother is 4 at the moment, since 4*3 is 12. in 4 years John will be 16 and his brother will be 8, and 8 is half of 16. so 16?
Answer:
Nothing too simplified in this. That's in its most simplified form.
Step-by-step explanation:
2) The slopes and y intercepts should be the same. In other words, the system of equations should overlap infinitely (meaning the lines overlap as “one line”).
3) y=3x+1 and y=3x-1 can be used for a system with no solutions. No value of x can make the equations equal.
