I don’t know if you can solve it since it is an expression?

The answer is X=1.5

x squared = 2.25 (1.5 x 1.5)

18 x 2.25 = 40.5

40.5 - 1.5 = 39

Find the sticker price and dealer's cost for the MT-5 Sedan with a base price of $10,600.00. Options cost $542.00, $140.00, $318

Bas_tet [7]

<h3>Answer:</h3>

sticker: $12,620
dealer's cost: $10,712

<h3>Step-by-step explanation:</h3>

The total cost of options is the sum of their individual costs.

total options = $542 +140 +318 +580 = 1580

The sticker price is ...

sticker price = base price + total options + destination charge

= $10600 +1580 +440

sticker price = $12,620

The dealer cost is ...

dealer cost = 82% × base price + 100% × total options + destination charge

= 0.82·$10600 +1580 +440

dealer cost = $10,712

In a science-fiction story, a spaceship travels 3 times faster each minute than it traveled during the minute before. If the shi

The expression is:

$speed(minutes)=3\frac{km}{h} ^{minutes} \\\\speed(15minutes)=(3^{15})\frac{km}{4} =14348907\frac{km}{g}$

Why?

From the statement we know that the spaceship travels 3 times faster each minute that it traveled during the minute before, it can be expressed using an exponential function, its base will be the starting speed (during the first minute).

The expression will be:

$speed(minutes)=(3^{minutes})\frac{km}{h} \\\\speed(15minutes)=(3^{15})\frac{km}{h}=14348907\frac{km}{h}$

Have a nice day!

Answer:

$\: x = 10$

Step-by-step explanation:

prefer the attachment

according to the question

$\displaystyle \: \frac{6}{17.5-x} = \frac{8 + 6}{17.5}$

simplify addition:

$\displaystyle \: \frac{6}{17.5-x} = \frac{14}{17.5 }$

simplify fraction;

$\displaystyle \: \frac{6}{17.5 - x} = 0.8$

cross multiplication:

$\displaystyle 6 = 14 - 0.8x$

cancel 14 from both sides:

$\displaystyle - 8= - 0.8x$

divide both sides by -0.8:

$\therefore \: x = 10$
