80 and 20
Step-by-step explanation:
80+80+20=180
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3
110-8.75= 101.25. 101.25 divided by 9 = 11.25. Each pizza cost 11.25
the easiest way is to make the fractions the same, with common denominators.
that means you have to multiply (1/4) by 2, to make it 2/8.
then you can see that she can make 3 total trips, not including driving back home.
