Answer:
The number is 9.
Step-by-step explanation:
Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.
80 - 3x = 5x + 8
First, let's add 3x to both sides.
80 - 3x + 3x = 5x + 3x + 8
80 = 8x + 8
Next, let's subtract 8 from both sides.
80 - 8 = 8x + 8 - 8
72 = 8x
Finally, let's divide both sides by 8.
72/8 = 8x/8
9 = x
<em>"x" is 9.</em>
<em>So the secret number is 9.</em>

Step-by-step explanation:
The value of N is 289.
Step-by-step explanation:
A sequence of number is given with a missing number "N".
To find N, find which pattern is followed in the sequence:
The sequence goes on reducing with small number than the previous one.
so, finding the difference= 400-361= 39
361-324= 37
It is found that 39-37= 2.
37-2= 35 and follows as 33 and 31.
So, the next number N can be find by 324-N= 35
324-35= N
N= 289
check whether the next number is followed correctly or not,
289-256 must give 33 and 256-225 gives 31. <u>So the N value is correct.</u>
I am pretty sure the correct solution would be 43.
You would add all the times: 30+45+30+60+50=215
And then you would divide that number by the amount of values: 215/5
This would give you the answer which is 43. Hope this helps!
