Mathematics

saul85 [17]3 years ago

Answer:

x = \sqrt{m(\frac{a}{b})^{2} +n  }

Step-by-step explanation:

a\sqrt{(\frac{x^{2} - n }{m}) } = \frac{a^{2} }{b}

\sqrt{\frac{x^{2} - n }{m} } = \frac{a}{b}   [Divide both sides by a]

\frac{x^{2} - n}{m} = (\frac{a}{b} )^{2}   [Square both sides]

x^{2} -n = m(\frac{a}{b} )^{2}   [Multiply both sides by m]

x^{2} =m(\frac{a}{b} )^{2}  + n   [Bring n to the right]

x = \sqrt{m(\frac{a}{b})^{2} +n  }   [Square root both sides]

The taxi fare in Metropolis is $3.75 for the first mile and additional mileage charged at the rate of $0.30 for each additional
Alexxx [7]

Answer:

Total charge

=

$

4.25

+

$

1.50

(

m

−

1

)

Total charge for 12 miles  

=

 

$

20.75

Explanation:

Building the rule

The trick with algebra is to think what you would do with numbers, then substitute letters.

Mile number 1 costs

$

4.25

The rest of the miles

⇒

(

total miles

−

1

)

×

$

1.50

Putting this all together we have:

$

4.25

+

(

total miles

−

1

)

×

$

1.50

The question instructs that we are to use the letter m for the total miles so we now have:

$

4.25

+

(

m

−

1

)

×

$

1.50

This would be written as:

$

4.25

+

$

1.50

(

m

−

1

)

So

 Total charge

=

$

4.25

+

$

1.50

(

m

−

1

)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Determine the charge for 12 miles

Total charge

=

$

4.25

+

$

1.50

(

12

−

1

)

Total charge

=

$

4.25

+

$

1.50

(

11

)

Total charge for 12 miles

=

$

4.25

+

$

16.50

 

=

 

$

20.75

Hope this helps you...
