Answer:

x = -8

Step-by-step explanation:

The first choice is the correct one, as is easily verified by putting it in the equation and evaluating:

... 6(-8-1) = 9(-8+2)

... -54 = -54

_____

You can solve the equation to get the same result.

... 6x -6 = 9x +18

... -24 = 3x . . . . . add -18-6x

... -8 = x . . . . . . . divide by the coefficient of x

5 2/3 gave to her 4 friends how much did each one receive

Olin [163]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

$5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3}$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\$

So each of her friends receive 17/12 .

_________________________________

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

$5 \times \frac{2}{3} = \frac{10}{3} \\$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\$

So each of her friends receive 10/12 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

The Penn's Landing Ferry sells deluxe and economy seats for each tour it conducts. In order to complete a tour, at least 28 econ

kenny6666 [7]

The maximum profit for 1 tour would be $2650

if there are 90 seats and 10 deluxe seats must be sold, you have to multiply 10 times 25 which gives you 250.

if there are 90 seats, 10 must be deluxe (which is cheaper), and you are trying to find the max profit for 1 tour, then 80 of the seats must be economy seats.
to find out how much 80 economy seats would cost you need to multiply 80 times 30 which gives you 2400.

then you need to add the profit of 80 economy seats and 10 deluxe seats and that would give you $2650

and $2650 would be the max profit you could make for 1 tour.
