Answer:

p = 11.2

Step-by-step explanation:

2.6(5.5p - 12.4) = 127.92

14.3p - 32.24 = 127.92

Add 32.24 to both sides

14.3p = 127.92 + 32.24

14.3p = 160.16

Divide both sides by 14.3 (the coefficient of p)

p = 11.2

Y = – 3

KonstantinChe [14]

The best approximation for the solution to this system of equations is (-2.2,-3)

Option C is correct.

Step-by-step explanation:

Solving the system of equations to get the exact value of x:

$y = -3\\y = x-0.8$

Let

$y = -3\,\,eq(1)\\y = x-0.8\,\,eq(2)$

Putting value of y from eq(1) into eq(2)

$-3=x-0.8$

$x=-3+0.8$

$x=-2.2$

So, Value of x is -2.2

The best approximation for the solution to this system of equations is:

x=-2.2 and y = -3

(-2.2,-3)

Option C is correct.
