I think its the 3rd option
Answer:
=5(9)+6+1. =45+7 =52
=52.move the x with the negative exponent into the denominator and change the sign. 1,3x'y+2xy-5y.solve when x = - 2;y = 3
Step-by-step explanation:
1/2, because you multiply your denominators together and your nominnators together, getting you 6/23, then you simplify to get 1/2.
Answer:
n = 1/2
Step-by-step explanation:
So the equation is 4/5n - 1/5 = 2/5n.
So, the first thing that we need to do is get the variable on one side.
So, to do that we need to subtract 4/5n on both sides.
Now our equation is -1/5 = -2/5n
Now the last step is to simplify.
To do that, we need to multiply by the reciprocal of 2/5 on both sides.
That leaves us with 1/2 = n
The 4th one is the answer
