Answer:

=6(1 + c)

Step-by-step explanation:

Given that:

= -2/3(12c-9)+14c

By simplifying:

Negative sign before bracket will alter the inner signs

=-24c/3 + 18/3 +14c

= -8c + 6 + 14c

= 6 + 6c

By taking 6 common:

=6(1 + c)

I hope it will help you!

Answer:

6(c + 1)

Step-by-step explanation:

Given: $ - \frac{2}{3} (\ 12c - 9 )\ + 14c $.

Distributing $ - \frac{2}{3}$ over $ 12c - 9 $ we get:

$ - \frac{2}{3} (12c) + \frac{2}{3} (9) + 14c $.

On simplifying we get: $ -2(4c) + 2(3) + 14c $

$ \implies -8c + 6 + 14c = 6c + 6 = 6(c + 1) $

Therefore the answer is $ 6(c + 1) $.

Help worth a lot of pounts
Anton [14]

Answer:

See below.

Step-by-step explanation:

Let x = amount of money you have in your account.

The money in your account plus the $125 extra that you need equals the total cost of the computer.

The equation is:

x + 125 = 2250

Now we solve the equation by subtracting 125 from both sides.

x = 2125

Answer: You have now $2125 in your account

PLEASE HELP ME THIS.. I REALLY NEED<br> HELP
Colt1911 [192]

9514 1404 393

Answer:

  5 hours

Step-by-step explanation:

A quick way to look at this is to compare the difference in hourly charge to the difference in 0-hour charge.

The first day, the charge is $3 more than $12 per hour.

The second day, the charge is $12 less than $15 per hour.

The difference in 0-hour charges is 3 -(-12) = 15. The difference in per-hour charges is 15 -12 = 3. The ratio of these is ...

  $15/($3/h) = 5 h

The charges are the same after 5 hours.

__

If you write equations for the charges, they will look like ...

  y1 = 15 + 12(x -1)

  y2 = 3 + 15(x -1)

Equating these charges, we have ...

  15 +12(x -1) = 3 + 15(x -1)

  12x +3 = 15x -12 . . . . . . . . eliminate parentheses

  15 = 3x . . . . . . . . . . add 12-12x

  x = 15/3 = 5 . . . . . . divide by 3

You might notice that the math here is very similar to that described in words, above.

The charges are the same after 5 hours.
