How about getting your parents to call your teacher if he/she is in the bed
The equation would be Black + brown
(2.3x^2 - 5.6x + 2.3) + (<span>2.4x^2 + 7.2x + 0.97)
combine all like terms:
4.7x^2+1.6x+3.27</span>
Unit rate means one. So the best way to solve this is using a proportion over one. If there are 258 pencils in 3 purses 258/3 then how many are in one purses x/1. Cross multiply next.
258/3 * x/1. You get 3x and 258. To get the x alone, divide both sides by three. Your answer is 86 pencils in one purse.
