By finding the least common denominator (LCD), and then go from there.
<span>Which ordered pair is the best estimate for the solution to the system?
</span>A. (2, −6.5)
2.25/12.50 = 0.18. then turn 0.18 into a percentage by doing 0.18 x 100 = 18%. Therefore, he gave an 18% tip.
For this case we have the following equation:

Rewriting we have:

For expressions to be equal, exponents must be equal. So:

To factor, we look for two numbers that, when multiplied, result in -3 and when added, result in -2. These numbers are -3 and 1.

Thus, the roots are:

Answer:


Cost per metre = Rs. 5
Total cost = Rs. 2000
Then total length of the fence = Rs.2000/Rs.5
= 400 metre
Total length of the fence = 400 metre
