Answer:
solving we get Solution set = {4,0}
Step-by-step explanation:
We are given system of equation:
Multiply eq(1) by 2 and eq(2) by -3
We get y=0,
Now finding x by putting value of y in eq(1)
So, solving we get Solution set = {4,0}
Answer: C.V=C1.V1 +C2.V2
Step-by-step explanation: C=(C1V1 + C2V2)/V -> C=(20%.V+25%V)/2V-> C=22,5%
1. Distributive
This is because you multiply the number outside the parentheses into the numbers inside the parentheses.
Hope it helped.
46
Divide 69 by 3
