9.58507409207 is rounded to the nearest whole number of 10
Answer:
1/2x - 8
Step-by-step explanation:
Let
x = number of pledges she collected last year
The number of pledges that Melissa collected for this year's charity walk is 8 less than half the number of pledges she collected last year.
Number of pledges she collected this year = 1/2x - 8
The expression which represents the number of pledges she collected this year = 1/2x - 8
Answer:
x=242/3
alternative form= 80 2/3, x=80.6
Step-by-step explanation:
3x-4y=242
substitute y = 0
3x-4x0=242
calculate the product
3x-0=242
remove 0
3x=242
divide both sides (by 3 in order to leave x by itself)
done
The objective function of a linear programming problem is a linear function.
A valid objective function is (b) Min 4x+3y+(2/3)z
The form of the objective function of a linear programming problem is:

The above function means that:
- The objective function cannot contain the product of the variables
- The objective function cannot contain the quotient of the variables
The above highlights mean that:
- The objective function can contain the sum of the variables
- The objective function can contain the difference of the variables
Hence, the valid objective function is (b) Min 4x+3y+(2/3)z
