Kitty [74]
<span>Potato salad=$2.25/(1 1/2)=$2.25/(1+0.5)=$2.25/1.5=$1.50 per pound
Ham=$2.00/(1/2)=$2.00/0.5=$4.00 per pound
Cheese: $0.60/(1/4)=$0.60/0.25=$2.40 per pound

A. 4 pounds of turkey, 1 pound of ham, and 1/2 pound of shrimp salad
1/2=0.5
Total cost: T
T=4($3.50)+1($4.00)+0.5($5.50)=$14.00+$4.00+$2.75→T=$20.75>$20  No

B. 1 1/2 pounds of cheese, 2 pounds of ham, and 1 1/2 pounds of shrimp salad
1 1/2=1+0.5=1.5
</span>Total cost: T
T=1.5($2.40)+2($4.00)+1.5($5.50)=$3.60+$8.00+$8.25→T=$19.85

The value of x in the equation \frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2} is x = -1 or x = -2

<h3>How to solve the equation?</h3>

The equation is given as:

\frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2}

Start by taking the LCM

\frac{4x(x - 2) - 5x(x - 1)}{(x - 1)(x -2)} = \frac{2}{x^2 - 3x + 2}

Expand the denominator

\frac{4x(x - 2) - 5x(x - 1)}{x^2 -3x +2} = \frac{2}{x^2 - 3x + 2}

Cancel out the common factor

4x(x - 2) - 5x(x - 1)= 2

Expand

4x^2 - 8x - 5x^2 + 5x = 2

Evaluate the like terms

-x^2 - 3x = 2

Rewrite as:

x^2 + 3x + 2 = 0\\

Expand

x^2 + 2x + x + 2 = 0

Factorize

x(x + 2) + 1(x + 2) = 0

Factor out x + 2

(x + 1)(x + 2) = 0

Solve for x

x = -1 or x = -2

Hence, the value of x in the equation \frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2} is x = -1 or x = -2
