Step-by-step explanation:
2x + 1 = 3x -3 + 4 ➡ 2x + 1 = 3x + 1
x = 0
So, since it is continuously, we need to think of PERT

So, we just plug our numbers in to solve for T

It will take 15.479 years
Answer
Find out the At how many hours of work will the total cost be the same for both families .
To prove
Let us assume that the number of hours at which the total cost be the same for both families be x .
As given
Smith's family contractor charges $16.50 per hour plus $289 in supplies .
Jackson's family contractor charges $18.75 per hour and $274.60 in supplies.
Than the equation becomes
16.50x + 289 = 18.75x + 274.60
16.50x - 18.75x = 274.60 - 289
-2.25x = -14.4

x = 6.4 hours
Therefore in 6.4 hours of work will the total cost be the same for both families .
Answer:
78
Step-by-step explanation:
50 questions worth 2 a piece and you miss 11 questions so we are going to take 2(11) off of 50.
We are doing 100-2(11).
100-22=78.
Or if you miss 11 questions you get 39 right. So 39(2)=78.
