Since a negative times a positive makes a negative you can change your equation to 7 - 5n=42. You can now subtract 7 from both sides to get -5n = 35. Next get divide -5 on both sides giving you n = -7.
In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials

4^3= 64
2^6= 64
Therefore, n=6.
You can also figure this out if you know that 2^3*2^6=2^9. When you multiply exponents with the same base, add the exponents. 3+6=9
Final answer: n=6
117miles/180minutes ~~ 117miles/3hours ~~ miles/hour(mph)
117miles ÷ 3hours = 39miles/hour or 39 miles per hour.
(<em>Speed=x</em>) Speed needed is: x ≥ 39mph.

When two fractions have the same numerators, the one with the smaller denominator is the greater fraction.

So Kelvin is right.
