Answer:
x = 1/2 or 0.5
Step-by-step explanation:
Subtract 2 from both sides of the equation
x + 2 - 2 = 5x -2
Simplify
x = 5x -2
Subtract 5x from both sides of the equation
x = 5x -2
x - 5x = 5x - 2 - 5x
Solution
x = 1/2

You would start by finding out how much 10 and 20 cost per copy
10: 40-25 = 15/10 = $1.50 dollars per copy
20 (This is for checking your math, not required): 55-25 = 30/20 = $1.50 dollars per copy
So, to find 15 copies you would use this formula: 25 + 1.5x
25 + 1.5(15)
25 + 22.5
$47.50 for 15 copies
Now for the second question:
160 - 25 = 135/1.5 = 90 copies
90 copies for $160
Yes it is. Also, a= 43 & b=43
Answer:
24
Step-by-step explanation:
add 5 to both sides to get 2x=16
divide both sides by 2
x=8
3(8)=24
Answer:
0.184
Step-by-step explanation:
As the statistician consultant, I would have to calculate the chance of having 2 ambulances on the freeway at this hours and relay the message to the dispatcher.
Probability of having the need for 2 ambulances.
We will have a poisson distribution:
Lambda = 1
P(x=2) = e^-2*1/2!
= 2.71828^-1/2
= 0.368/2
= 0.184
I would tell the dispatch rider that the possibility that 2 ambulances would be required is 0.184.
Thank you
