1) (-2x+4)+(x-6) is simplified into =-x-2

2)  (uv-3)+(4uv+1)  is simplified into 5uv-2\\

3) (11x-8)-(2x+3) is simplified into -9x-11

4) (x^2-4)-(x-2) is simplified into x^2-x-2

5) (12-3t-7t^2)+(1+3t-t^2) is simplified into -8t^2+13

Step-by-step explanation:

We need to solve the polynomials.

1) (-2x+4)+(x-6)

Solving:

(-2x+4)+(x-6)\\=-2x+4+x-6\\Combining\,\,like\,\,terms:\\=-2x+x+4-6\\=-x-2

So, (-2x+4)+(x-6) is simplified into =-x-2

2) (uv-3)+(4uv+1)

Solving:

(uv-3)+(4uv+1)

Expanding:

=uv-3+4uv+1\\Combining\,\,like\,\,terms:\\=uv+4uv-3+1\\=5uv-2\\

So,  (uv-3)+(4uv+1)  is simplified into 5uv-2\\

3) (11x-8)-(2x+3)

Solving:

(11x-8)-(2x+3)

Expanding:

=11x-8-2x-3\\Combining\,\,like\,\,terms:\,\,\\=11x-2x-8-3\\=-9x-11

So, (11x-8)-(2x+3) is simplified into -9x-11

4) (x^2-4)-(x-2)

Solving:

(x^2-4)-(x-2)

Expanding:

=x^2-4-x+2\\Combining\,\,like\,\,terms:\\=x^2-x-4+2\\=x^2-x-2

SO, (x^2-4)-(x-2) is simplified into x^2-x-2

5) (12-3t-7t^2)+(1+3t-t^2)

Solving:

(12-3t-7t^2)+(1+3t-t^2)

Expanding:

=12-3t-7t^2+1+3t-t^2\\Combining\,\,like\,\,terms:\\=12+1-3t+3t-7t^2-t^2\\=13+0t-8t^2\\=-8t^2+13

So, (12-3t-7t^2)+(1+3t-t^2) is simplified into -8t^2+13

Solving the linear equations variable on one side
Brums [2.3K]

The pick up fee is $2.50.

After each mile, $1.95 is added.

That is, after the first mile, we have;

\begin{gathered} \text{Fe}e=\text{ 2.50 + 1.95(1)} \\ \text{After the second mile, we have;} \\ Fee=\text{ 2.50+1.95(2)} \end{gathered}

Isaac total charge = $27.46;

Generally, let the number of miles driven by the taxi be x, then we have;

1.95x+2.50=27.46

Solving for the number of miles Isaac travelled, we have;

\begin{gathered} 1.95x=27.46-2.50 \\ 1.95x=24.96 \\ x=\frac{24.96}{1.95} \\ x=12.8\text{miles} \end{gathered}

CORRECT OPTION:

1.95x+2.50=27.46;\text{ Isaac traveled 12.8 miles.}
