Question

Raoul prints a poster using an aspect ratio of

Answer 1

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

Answer 2

Which of the following aspect ratios could Raoul also use without distorting the picture?

Answer 3

\[\frac{ 1 }{ 4 }\]

Answer 4

\[\frac{ 5 }{ 6 }\]

Answer 5

\[\frac{ 8 }{ 10 }\]

Answer 6

or \[\frac{ 8 }{ 9 }\]

Answer 7

i think the question is asking
"what fraction is equivalent to \(\frac{4}{5}\)?"

Answer 8

idk i just putwhat the question says

Answer 9

k
which fraction is equivalent to \(\frac{4}{5}\) out of your list?

Answer 10

8/10?

Answer 11

yes

Answer 12

so thats the answer?

Answer 13

yes

Answer 14

thx :)

Answer 15

Which pair of ratios forms a proportion?
\[\frac{ 11 }{ 36 },\frac{ 121 }{ 180 }\]

Answer 16

\[\frac{ 13 }{ 21 },\frac{ 39 }{ 63 }\]

Answer 17

\[\frac{ 14 }{ 23 },\frac{ 70 }{ 92 }\]

Answer 18

or\[\frac{ 20 }{ 51 }, \frac{ 4 }{ 5 }\]

Answer 19

not the last one for sure

Answer 20

this is what you do to check the first one
with a calculator,
\[11\times 180\] and
\[36\times 121\]
if those numbers are the same,then the fractions are equal
if not, they are not

Answer 21

ok so not the first on not the last one?

Answer 22

right

Answer 23

for the second one, compute
\[13\times 63\] and \[21\times 39\] and see if they are equal

Answer 24

yes so it is the second one

Answer 25

yes

Answer 26

Which ratio forms a proportion with\[\frac{ 4 }{ 5 }\]

Answer 27

\[\frac{ 2 }{ }\]

Answer 28

\[\frac{ 4 }{ 10 }\]

Answer 29

\[\frac{4}{5}=\frac{8}{10}=\frac{12}{15}=\frac{16}{20}=...\]

Answer 30

multiply the top and bottom by the same number, and you get the same fraction

Answer 31

Solve the x proportion for \[\frac{ 3 }{ x+2 }=\frac{ 6 }{ x-1 }\]

Answer 32

x = −5

x = 1

x = 4

x = 5

Answer 33

cross multiply and solve
\[3(x-1)=6(x+2)\]

Answer 34

uh

Answer 35

do you have any idea what i mean?

Answer 36

ys

Answer 37

ok then the first step is to use the distributive property to remove the parentheses

Answer 38

how are you supposed to multiply 3 by x-1

Answer 39

\[a(b-c)=ab-ac\] so
\[3(x-1)=3\times x-3\times 1\] more succinctly written as
\[3x-3\]

Answer 40

so the answer?

Answer 41

do the same thing on the right, with the \(6\) and the \((x+2)\)

Answer 42

maybe it is better if we try this:
you have 4 possible answers
replace \(x\) by the answers given and see which one works
for example, if \(x=4\) then you get
\[\frac{3}{4+2}=\frac{6}{4-1}\] or
\[\frac{3}{6}=\frac{6}{3}\] which is definitely false, so it is not \(\)

Answer 43

try \(x=-1\) and see what you get

Answer 44

like im not even taking this class i cant have the answer?

Answer 45

lol yeah i told you how to get it
where is says "solution" here
www.wolframalpha.com/input/?i=\frac{+3+}{+x%2B2+}%3D\frac{+6+}{+x-1+}

Answer 46

http://www.wolframalpha.com/input/?i= \frac{+3+}{+x%2B2+}%3D\frac{+6+}{+x-1+}

Answer 47

guess you have to copy and paste

Answer 48

Solve for x in the proportion \[\frac{ 9 }{ 27x }=\frac{ x }{ x+3 }\]

Answer 49

here this should work
http://www.wolframalpha.com/input/?i=3%2F%28x%2B2%29%3D6%2F%28x-1%29

Answer 50

if you just want the answer, type it in just as you see it
you will get it where it says "solution"

Answer 51

idk what to type in!

Answer 52

exactly what you wrote
look at my example

Answer 53

you can even copy and paste what you wrote above

Answer 54

that wasnt any answer options

Answer 55
