Answer:
A
Step-by-step explanation:
Speed = distance/ time
=10km/ 1hr(60mins)
= 10km/ 1hr
=10km/hr
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
Answer:
10
Step-by-step explanation: substitute 2 for all the x’s and add.
The answer is 6 because you do this
1/3 of 18 divide 18 by 3 amd get 6
