Solve using Combining Like Terms (CLT) 7 + 4d + 5d = 7d + 3

Mathematics
1 answer:
Vesnalui [34]3 years ago
3 0

Answer:

d= -2

Step-by-step explanation:

7 + 4d + 5d = 7d + 3

Combine like terms

7+9d = 7d+3

Subtract 7d from each side

7+9d-7d = 7d-7d+3

2d +7 = 3

Subtract 7 from each side

2d+7-7 = 3-7

2d = -4

Divide each side by 2

2d/2 = -4/2

d = -2

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

Can someone explain to me how to do this and give me the answer please?​
pantera1 [17]

Answer:

To find x, y, z, p and q, you need to know about the property of Rhombus.

13y + 10 = 7y + 16 (pair of equal opposite sides)

=> 6y = 6

=> y = 1

x = 7x + 16 (2 equal adjacent sides)

  = 7*1 + 16

  =23

z = 90 deg (angle between 2 diagonals)

q = 22 deg (isosceles triangle)

p = 90 - 22 = 68 deg (right triangle)
