AleksandrR [38]

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

$4T + 7F = 38.3$

$5T + 5F = 40.75$

Required

Determine the values of T and F

$5T + 5F = 40.75$

Divide through by 5

$T + F = 8.15$

Make F the subject

$F = 8.15 - T$

Substitute 8.15 - T for F in the first equation

$4T + 7F = 38.3$

$4T + 7(8.15 - T) = 38.30$

$4T + 57.05 - 7T = 38.30$

Collect Like Terms

$4T - 7T = 38.30 - 57.05$

$-3T = -18.75$

Solve for T

$T = -18.75/-3$

$T = 6.25$

Recall that:

$F = 8.15 - T$

$F = 8.15 - 6.25$

$F = 1.90$

Delicious77 [7]

The easiest way it to solve it.
${x}^{2} + 5x + 2 = 0$
You have
$\rho = 25 - 4 \times 1 \times 2 = 17$
Thus
$x = \frac{ - 5 \pm \sqrt{17} }{2}$
