Answer:
Step-by-step explanation:
When you multiply and irrational by a rational, you are doing nothing to change the nature of an irrational number. The two numbers have different kinds of properties and though a multiplication can be indicated, there is no way you can change the properties of an irrational number with a rational.
Their properties just do not mix.
It is like take a solvent and mixing it with something that is not a solvent. You cannot do anything to anything to the insolvent to make it solvent simply by adding more. Their properties remain in tact.
Take 3 * 4√7
The properties of the 3 and 4 remain the same when multiplied and they can be combined. 3*4 = 12
But nothing can be done with √7. The 3 cannot effect it, anymore than what the 4 did.
Answer:
n + 7/5
Step-by-step explanation:
<u>Solve</u>
Let "n" be the varable.
Add 7 = +
Then, Divideby 5 = ÷
Therefore, the equation for this is n + 7 ÷ 5
Answer:

Step-by-step explanation:

The two fraction have the same denominator , so put them under a common denominator

Simplify
-7-4=-11

write in mixed fraction form

Answer:
D) 2X + 4Y = 6
3X - 4Y =9
Step-by-step explanation:
Adding the equations can be informative. The sums are ...
A) 0 = 11 . . . . . no solution
B) 0 = 0 . . . . . infinite solutions
C) 0 = 2 . . . . . no solution
D) 5X = 15 . . . one solution (x, y) = (3, 0)
