Answer:

Subtract 3 and one-fifth from both sides of the equation

Step-by-step explanation:

Well to find n you gotta separate it.

3 1/5 + n = 9

-3 1/5

n = 5.8

<em>to seperate it you subtract 3 1/5 from both sides.</em>

Answer:

Step-by-step explanation:

$a+c=236\\ \\ a=236-c\\ \\ 1.5c+2.5a=525\\ \\ 1.5c+2.5(236-c)=525\\ \\ 1.5c-2.5c+590=525\\ \\ -c=-65\\ \\ c=65\\ \\ a=236-65\\ \\ a=171\\ \\ \text{So there were 171 adults and 65 children at the pool that day.}$

I need help answering the question in the photo

Lana71 [14]

Given:

Results of a spinner shown in the table.

To find:

The experimental probability of the spinner landing on a 1 or 7.

Solution:

From the given table it is clear that,

Spinner landing on 1 = 12 times

Spinner landing on 7 = 9 times

Spinner landing on 1 or 7 = 12+9 = 21 times

Total number of times spinner landed = 12+35+72+29+40+18+9+65+42 = 322 times

Now, the experimental probability of the spinner landing on a 1 or 7 is

$P=\dfrac{\text{Spinner landing on 1 or 7}}{\text{Total number of times spinner landed}}$

$P=\dfrac{21}{322}$

$P=0.06521739$

$P\approx 0.065$

Therefore, the correct option is A.
