Answer 7

can u help me on another one

Answer 8

sure

Answer 9

An airline had a policy of maintaining a certain ratio of the number of members of cabin crew to the number of passengers, on every flight. A certain flight had a six member cabin crew on board. The following equation represents this information, where x is the maximum number of people, including the crew, on that flight.

x = 6 + twenty three-twenty fourthsx

How many passengers were on that flight?

Answer 10

do u know how to do it

Answer 11

what do you mean with twenty fourthsx

Answer 12

\[23/24x\]

Answer 13

23 over 24 x

Answer 14

\[x=6+\frac{ 23 }{ 24 }x\]

Answer 15

What do you think you do first

Answer 16

distribute the 6

Answer 17

yes

Answer 18

\[x-6=\frac{ 23 }{ 24 }x\]

Answer 19

IS this right?

Answer 20

i dont know what to do next

Answer 21

yeah

Answer 22

When you have an X like that you can change it to:\[x−6=\frac{ 23x }{ 24 }\]

Answer 23

Do you know what to do now?

Answer 24

distribute the 24 over???

Answer 25

Yep, by multiplying

Answer 26

yeah then add the like terms right

Answer 27

So you will get:\[24x-144=23x\]
And yes add the like terms

Answer 28

idk whats next

Answer 29

Is this right?\[-x=-144\]

Answer 30

yeah

Answer 31

How do you make the x positive?

Answer 32

thanks Which of the following is not equivalent to the formula for the circumference of a circle, C = 2 pir ?

c over quantity r times pi equals 2

c over quantity 2 times pi equals r

c over quantity 2 times r equals pi

2 times pi over c equals r

Answer 33

is it d

Answer 34

That is correct

Answer 35

4 over 5 y + 2 =6

Answer 36

What should you do first?\[\frac{ 4 }{ 5 }y+2=6\]

Answer 37

subtract the 2

Answer 38

Yep

Answer 39

\[\frac{ 4 }{ 5 }y=4\]

Answer 40

then mutiply the 4/5

Answer 41

What can you do with the \[Y\]

Answer 42

Remember now \[\frac{ 4y }{ 5 }=4\]

Answer 43

move the 5

Answer 44

over

Answer 45

yes by multiplying

Answer 46

so 4y=20

Answer 47

Yes\[4y=20\]

Answer 48

Now what

Answer 49

then divide the 4 into 20 which is 5 soo y=5

Answer 50

\[Great\] \[Job\]

Answer 51

yeah

Answer 52

Write the equation of the line in slope-intercept form that passes through the point (3, -2) and has a slope of 2.

Answer 53

Are you doing \[y=mx+b\]

Answer 54

yeah

Answer 55

What does M equal

Answer 56

slope

Answer 57

So then fill it in

Answer 58

y=2x+??

Answer 59

Ok when you have (3, -2) what does 3 and -2 mean

Answer 60

3 is the y and the -2 is x

Answer 61

good so fill that into the equation

Answer 62

\[3=2(-2)+b\]

Answer 63

3=2(-2)+b

Answer 64

3=-4+b

Answer 65

No combine like terms

Answer 66

b=7

Answer 67

Now fill that in for "b" in this equation:\[y=2x+_\]

Answer 68

y=2x+7

Answer 69

That is correct :D><

Answer 70

2 + (a + b) = (2 + a) + b is an example of which algebraic property?

Distributive Property

Associative Property of Addition

Commutative Property of Addition

Symmetric Property

Answer 71

r u good with this stuff

Answer 72

I am great in math that is why I am in head in school

Answer 73
