For the equations given below, which statement is true?
allochka39001 [22]

Answer: C. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.

Step-by-step explanation:

You know that the first equation is:

-3x-8=19

And the second equation is:

-3x-2=25

According to the Addition property of equality:

If a=b; then a+c=b+c

Then, you can add 6 to both sides of the first equation to keep it balanced. Then, you get:

-3x-8=19\\\\-3x-8+(6)=19+(6)

-3x-2=25

Therefore, you can observe that the second equation can be obtained by adding 6 to both sides of the first equation, therefore, the equations have the same solution.

If you want to verify this, you can solve for "x" from both equations:

- First equation:

-3x-8=19\\\\-3x=19+8\\\\x=\frac{27}{-3}\\\\x=-9

- Second equation:

-3x-2=25\\\\-3x=25+2\\\\x=\frac{27}{-3}\\\\x=-9

The cost, C dollars, of hiring a taxi is given by the formula C=2.00+320n, where n is the number of tenths of a mile driven. Wha
Ainat [17]

Answer:

$14.80

Step-by-step explanation:

I'm assuming you meant to put 3.20 since $320 a mile would be ridiculous.

C(n)=2.00+3.20n

If n = 4 miles we have:

C(4)=2+3.20(4)

C(4)=2+12.80

C(4)=14.80

So the cost of the taxi is $14.80.
