Asking this for a third time now

You buy a watch for $60. There is a 6% sales tax. What is your total cost for the<br> watch?

lara [203]

Answer:

$63.3

Step-by-step explanation:

You buy a 60 dollar watch.

60

There is a 6 percent tax. When adding tax, multiply the 6 percent by the original amount.

60 x 0.06

3.6

Add the tax to the original amount.

60 + 3.6 = 63.3

So, your total cost is 63.3 dollars.

Which of the points (s, t) is inside the shaded region of the set of inequalities shown below?

sergejj [24]

Answer:

Only point C. (9,4)

Step-by-step explanation:

To check if the points are inside the region of the inequalities, we just need to use the values of the point in each inequation, and if the point satisfy all inequations, the point is inside the region.

point A = (1,8): s = 1 and t = 8

first inequation: s<24 - 0.66t

1 < 24 - 0.66*8

1 < 18.72 (true)

second inequation: s>12 - t

1 > 12 - 8

1 > 4 (false)

So point A is not inside the region.

point B = (-9,21): s = -9 and t = 21

As we can see from the fourth inequation, the s value needs to be greater than 0, and point B has s negative, so point B is not inside the region.

point C = (9,4): s = 9 and t = 4

first inequation: s<24 - 0.66t

9 < 24 - 0.66*4

9 < 21.36 (true)

second inequation: s>12 - t

9 > 12 - 4

9 > 8 (true)

third inequation: s< 30 - t

9 < 30 - 4

9 < 26 (true)

fourth inequation: s>0

9 > 0 (true)

fifth inequation: t>0

4 > 0 (true)

As all conditions are true, point C is inside the region.

point D = (30,10): s = 30 and t = 10

first inequation: s<24 - 0.66t

30 < 24 - 0.66*10

30 < 17.4 (false)

So point D is not inside the region.

3x + 2y = 10 2x + 3y = 15/2

Zinaida [17]

Hello Friend!

Solve the following system of equations:

$3 * [3x + 2y = 10] ---\ \textgreater \ 9x + 6y = 30$
$2 * [2x + 3y = 15/2]--\ \textgreater \ 4x + 6y = 15$

$Subtract: 5x = 15$

$Solve: x = 3$

In Other Words, $[(3, 1/2) ]$ OR $x = 3, y = 1/2$ .
<span>
Option "D".

Which expression is equivalent to -2(3a + 6b) + (4a - 2b)? A) -2(a + 7b) B) -2(a - 7b) C) 2(a + 7b) D) 2(a - 7b)

leonid [27]

I would go with A because if u use the distributive property u get something very similar
