Answer:

16

Step-by-step explanation:

To solve this equation you need to do the opposite to factor everything out. Since the 6 is being multiplied you need to divide it by 6 and whatever you do to one side you do to the other:

48=1/2b(6)

6÷6=1

48÷6=8

8=1/2b

Multiplying by 1/2 is the same as dividing by 2. So what we want to do is multiply by 2:

8=1/2b

1/2×2=1

8×2=16

16=b meaning you base is 16

To check your answer you can put 16 in as b

48=1/2(16)6

48=1/2(96)

Remember multiplying by 1/2 is the same as dividing by 2:

48=48

Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.
Cerrena [4.2K]

Answer:

Non-mutually exclusive

Step-by-step explanation:

both events can happen simultaneously... 3 is an odd number, events A and B  have a common outcome.

It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.

Y= x^2 -5 solve for x
dexar [7]

Y= x^2 -5

We need to solve for x, we need to get x alone

Y= x^2 -5

Lets start by removing -5

Add 5 on both sides

y + 5= x^2 -5 + 5

y + 5= x^2

Now to isolate x , we need to remove the square from x

To remove square , take square root on both sides

+-\sqrt{y+5} = \sqrt{x^2}

square and square root will get cancelled

+-\sqrt{y+5} = x

So x = +\sqrt{y+5} and  x = -\sqrt{y+5}
