Answer:
462 mi
Step-by-step explanation:
Gloria gets 420 mi/tank.
10 % of 420 is
420 × 0.10 = 42 mi
She will be able to drive an extra 42 mi.
420 + 42 = 462 mi
With her new tires, a tank of gas will take her 462 mi.
Y=125,000 (1+.035)^10
Y=125,000 (1.035)^10
Y=125,000 (1.410598716) or 125,000 (1.41)
Y= $176324.85 or $176250
We have been given a system of nonlinear equations.

In order to solve this system we can first equate the two equations in order to get a quadratic in x.

Our next step is to bring all the terms on one side.

Now we have to solve this equation. We can solve it by factoring using the splitting middle term method.



Upon setting each of these factors equal to zero using zero product property we get

Upon solving both these equations we get

Now we can substitute these values of x in the equation

We get


Therefore, our final set of solutions are

One-third of a number......1/3n
increased by 12....+ 12
(1/3)n + 12
