Answer:
19
Step-by-step explanation:
8+4=12 +7=19
Answer:
As critical path is the longest path during estimation,so 50 days is maximum time to complete this project.So probability to complete a project before 0n 50 days or before 50 days days is 1
Pr=1
Given:
Consider the given equation is:

To find:
The slope of the line that is represented by the given equation.
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the slope of the given equation is
.
Answer:
9h² + 51h + 28
Step-by-step explanation:
(5h + 4)(4h + 7)
=> 9h² + 35h + 16h + 28
=> 9h² + 51h + 28
Therefore, 9h² + 51h + 28 is the simplified expression.
Hoped this helped.
Our current equation is:
-8r -31 = -3(5r -6)
To solve for this, we need to get r on one side of the equation and then simplify if needed.
On the right side of the equation, we have a pending Distributive Property, which is when you multiply the number/variable outside of the parenthesis by all numbers/variables in the parenthesis.
Let's simplify this Distributive Property to help understand our equation better.
-3(5r -6)
Multiply -3 by each number/variable separately (unless they are already being multiplied, like 2x, 1/2x, etc).
-3(5r) + -3(-6).
-3(5r) = -15r
-3(-6) = 18 (both negatives need to be in parenthesis to keep a product as negative, and if you do not multiply them in that way, you will end up with a positive product).
Your equation now is:
-8r -31 = -15r + 18
Add 15r to both sides to get r on one side.
7r -31 = 18 is now our current equation.
Add 31 to both sides to get 7r by itself.
7r = 49 is now our equation.
r is still being multiplied by 7, so we need to do the opposite of multiplying by 7.
Divide both sides by 7.
r = 7.
I hope this helps!
