Evaluate 33/5 - 1/10

azamat

Answer:

$\large\boxed{\dfrac{13}{2}=6\dfrac{1}{2}=6.5}$

Step-by-step explanation:

We have the different denominators.

The common denominator is 10.

$\dfrac{33}{5}=\dfrac{33\cdot2}{5\cdot2}=\dfrac{66}{10}$

We can subtract these fractions now.

$\dfrac{33}{5}-\dfrac{1}{10}=\dfrac{66}{10}-\dfrac{1}{10}=\dfrac{66-1}{10}=\dfrac{65:5}{10:5}=\dfrac{13}{2}\\\\\dfrac{13}{2}=\dfrac{12+1}{2}=6\dfrac{1}{2}$

Find the values of x and y that maximizes the objective function P=3X+2Y for the graph. what is the maximum value?

diamong [38]

Substitute in the 3 points to find the values.

P(0,8) = 3(0) + 2(8) = 16 
P(5,4) = 3(5) + 2(4) = 15 + 8 = 23 
P(9,0) = 3(9) + 2(0) = 27 

Therefore (9,0) is the maximum value.
