2/3x -3.2 = -8.1 please help

andriy [413]

Answer:

x = -7 - 17/20 or -157/20

Step-by-step explanation:

2x/3 - 3.2 = -8.1

2x - 9.6 = -24.3

20x - 96 = -243

20x = -157

x = -157/20

x = -7 - 17/20

Group of 7 people spend 33.50 movie tickets 6.50 adults and 3.50 for child ticket. Which system of equation could be used to fin

kramer

The answer is
x + y = 7
6.50x + 3.50y = 33.50

x - the number of adult tickets
y - the number of child tickets

<span>Group of 7 people: x + y = 7
</span> 6.50 adults and 3.50 for child ticket cost <span>33.50: 6.50x + 3.50y = 33.50

So, we have two equations:
</span>x + y = 7
6.50x + 3.50y = 33.50

• What is the solution to 5x+ 20 = 7(x+2)?

o-na [289]

For this case we must find the solution of the following equation:

$5x + 20 = 7 (x + 2)$

Applying distributive property on the right side of the equation we have:

$5x + 20 = 7x + 14$

Subtracting 7x from both sides of the equation:

$5x-7x + 20 = 14\\-2x + 20 = 14$

Subtracting 20 from both sides of the equation:

$-2x = 14-20$

Different signs are subtracted and the major sign is placed.

$-2x = -6$

Dividing between -2 on both sides of the equation:

$x = \frac {-6} {- 2}\\x = 3$

Thus, the solution of the equation is $x = 3$

Answer:

$x = 3$

Suppose a basketball player has made 390 out of 434 free throws. If the player makes the next 2 free throws, I will pay you $40.

alukav5142 [94]

Answer: a) -$0.19, b) -$111.72 .

Step-by-step explanation:

Since we have given that

Number of free throws = 434

Number of throws made by them = 390

Amount for making the next 2 free throws = $40

Amount otherwise he has to pay = $169

a) Find the expected value of the proposition.

Expected value of success in next 2 free throws = $\dfrac{390}{434}\times \dfrac{391}{435}=0.8077$

Expected value would be

$0.8077\times 40+(1-0.8077)\times -169\\\\=32.308-32.4987\\\\=-\$0.19$

b) If you played this game 588 times how much would you expect to win or lose?

Number of times they played the game = 588

So, Expected value would be

$588\times -0.19\\\\=-\$111.72$

Hence, a) -$0.19, b) -$111.72
