Answer 26

idk why is shows thos question marks

Answer 27

what do you mean?

Answer 28

for #2. y is just unknown number, and we know that for each person, movie ticket costs $5

Answer 29

do you see these: � in my question

Answer 30

so you just multiply number of people by cost of movie ticket

Answer 31

how many people are there?

Answer 32

� may be some kind of strange symbols you copied

Answer 33

we don't know, so we can just call them "y"

Answer 34

y is just variable, to hold in place for unknown number. get it?

Answer 35

we can use " ? " as unknown number, but there may be more than two different unknown numbers, so we use letters instead

Answer 36

Answer 47

A?

Answer 48

yep

Answer 49

okay sweet

Answer 50

did you open the pic?

Answer 51

for #8, problem says that r = 60 mph and t = 3 hours

Answer 52

yeah I did

Answer 53

for #8, you just plug in 60 for r and 3 for h then solve for d

Answer 54

Yeah its D

Answer 55

So you have \(d = \color{red}r\color{blue}t \\ d = (\color{red}{60})(\color{blue}3)\)

Answer 56

that's right

Answer 57
