24.8 km

Step-by-step explanation

To do this we would just multiply 24.8 by 10,000 which is 248000 and if we divide that by 10000 (to get km) we would get 24.8km

Solve the system by substitution.

kirill [66]

<h2>Answer:</h2>

x = 1

y = 1

<h3>Step-by-step explanation:</h3>

$y=-3x+4\\ y=x$

Substitute into one of the equations

$-3x+4=x$

Rearrange variables to the left sider of the equation

$-3x-x=-4$

Combine like terms

$-4x=-4$

Divide both sides of the equation by the coefficient of variable

$x=\frac{-4}{-4}$

Determine the sign for multiplication or division

$x=\frac{4}{4}$

Cross out the common factor

$x=1$

Substitute into one of the equations

$y=1$

The solution of the system is

$\left \{ {{x=1} \atop {y=1}} \right.$

<em>I hope this helps you</em>

Help me math is not my thing and plz tell me how you did it

We need to get m by itself. to do that, we divide each side of the equation by -3.3. so, m = 0.333 (repeating decimal).

$n^{3}$ -4 $n^{2}$ +6n-24
factor out $n^{2}$ from the first two values and 6 from the last two values:
$n^{2}$ (n-4)+6(n-4)
( $n^{2}$ +6)(n-4) is your final answer
