The multiplicative inverse of a number x is a number y such that their product xy is 1.
So, we want a number such that

Divide both sides by 10:

5
0-(-5) =5. ( big minus small)

Answer:

C is correct Option
Step-by-step explanation:
Let,
Base of the triangle = b = 16
Perpendicular of the triangle = p = 21
Hypotenuse of the triangle= h = ?
According to Pythagoras theorem;






She should use the spinning wheel because its a 2/12 chance, with a wheel its a 1/6 chance.
A and C are irrational.
We know that B is rational because it's just asking 8 - 5, which is 3.
There is, however, no perfect square root of 73 or 56, and so the answer will be irrational.
