Mary purchased 4 tires by mail order. She paid $63.80 per tire plus $4.20 per tire for shipping and handling. There is no sales

tax, because the tires were purchased out of state. She also had to pay $7.41 per tire for mounting and balancing. At a local store, Mary's total for the 4 tires with mounting and balancing would be $356 plus 6% sales tax. How much did Mary save by purchasing the tires through the mail?

Lerok [7]

Answer:

9*10^{12}km

Step-by-step explanation:

9,460,730,472,580.8 km

First, we can work out 5% of our number, by multiplying it by 0.05

9,460,730,472,580.8 * 0.05 = 473,036,523,629

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}

We can see that 9*10^{12} is in the range of valid answers, as:

8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}

So, our final answer is:

9*10^{12}km

Solve the following by factoring. 12x^2 -7x -12 = 0
nirvana33 [79]

Solution:

The given equation is

12x^2 -7x -12 = 0

Now we will factor the middle term as per the ac-method because the given equation is a quadratic equation.

12x^2 -7x -12 = 0\\\\12x^2-16x+9x-12=0\\\\4x(3x-4)+3(3x-4)=0\\\\(3x-4)(4x+3)=0\\\\3x-4=0,or, 4x+3=0\\\\x=\frac{4}{3},x=\frac{-3}{4}\\
