Marking brainliest to whoever can help and explain

lyudmila [28]

Answer: I hope I got it right. You can mark brainliest if you want. I don't really care.

Step-by-step explanation:

Well, it seems that for every week, Pragitha swims x + 2 laps. So if she swims x + 2 laps twice, she will get 2x + 4. So x is equal to 4. You add that four and you get three x. So for one week, she swims x + 2 laps and for the second lap, she swims 2x + 4. Which according to the table, is equal to 3x. So for 3 weeks, she clearly swims less, because maybe she's tired or something. So it's 2x+1. And for week 4, it's week one and week 2 combined.

The expression on the other hand is

10x + 9

Can someone help me please.... with number 6,7,8,9

Alenkasestr [34]

Answer :

6. x=28

7.x =6

8. x =9

9. x =9

Step-by-step explanation:

$\frac{x + 2}{10} = 3$

$x + 2 = 3 \times 10 \\ x + 2 = 30 \\ x = 30 - 2 \\ x = 28$

(x+2)/10 = 3

Cross multiply

x+2 = 10 ×3

x+2 =30

Collect like terms and simplify

x =30-2

x = 28

$8x + 9 - 5x = 27 \\ 8x - 5x = 27 - 9 \\ 3x = 18$

$\frac{3x}{3} = \frac{18}{3} \\x = 6$

8x +9 -5x= 27

Collect like terms and simplify

8x-5x =27-9

3x =18

Divide both sides of the equation by 3

3x/3 = 18/3

x = 6

10x+8=8x+26

Collect like terms

10x-8x=26-8

2x = 18

Divide both sides of the equation by 2

2x/2 = 18/2

x = 9

2(x-5)+4x=x+35

Use 2 to open the bracket

2 × x =2x

2×(-5) =-10

2x-10+4x =x+35

Collect like terms and simplify

2x+4x-x = 35+10

5x = 45

Divide both sides of the equation by 5

5x/5 = 45/5

x =9

Eli, a pretty smart ape in the Salt Lake City zoo, has correctly picked the winner of the last 7 Super Bowls. Read about Eli's p

Anna [14]

Answer:

There is a 0.78% probability that Eli chooses 7 winners in a row.

Step-by-step explanation:

There were 7 Super Bowls.

In each Super Bowl, there were two teams.

So, the probability that Eli chooses 7 winners in a row is

$P = \frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2} = \frac{1}{128} = 0.0078$

There is a 0.78% probability that Eli chooses 7 winners in a row.
