Answer:
14,15,16
Step-by-step explanation:
Let x be the first number
Consecutive means in a row
x+1 is the second number
x+2 is the third number
x+ x+1 + x+2 = 45
Combine like terms
3x+3 = 45
Subtract 3 from each side
3x+3-3=45-3
3x = 42
Divide each side by 3
3x/3 = 42/3
x =14
The first number is 14
The second number is 14+1 = 15
The third number is 14+2 =16
The independent quantity is 20-25 hours per week because time will go on no matter what. The dependent quantity is the amount of money Windiest is paid per hour.
Answer:
2
Step-by-step explanation:
We must first solve the first equation to solve the second question. If we make up an answer for each variable in the first equation, it will make it easier to solve the next. Now lets say that each of the fractions will be equal to 1/3. We can then find out that x=2, y=4, and z=4012. We then have to factor the second equation's fractions. we can factor out x, y, and z out of each fraction respectively. The equations become the same as the first set, but x, y, and z instead of 1, 2 and 2006. because we know that x=2, y=4, and z=4012, we can simplify each fraction to become 2/3, and add these fractions up to equal 2.
Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:
From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.
