Question

WILL GIVE MEDAL AND FAN!

Answer 1

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 20 child bikes and 6 adult bikes in the week.

Answer 2

i thought ur picture was something else XD

Answer 3

A.No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
B.No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
C.Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
D.Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answer 4

its inappropriate i cant say XD

@quickstudent @ganeshie8 @Hero

Answer 6

PLZ HELP

Answer 7

@iloveW.M.B<3.<3 its chocolate

Answer 8

@zepdrix @thomaster

Answer 9

I know its not A or C

Answer 10

I think it is c becuase\[4c + 6a = 120 4(10) + 6(12) <= 120 40 + 72 <= 120 112 <= 120 -- this is correct 4c + 4a <= 100 4(10) + 4(12) <= 100 40 + 48 <= 100 88 <= 100 -- this is correct\]

Answer 11

No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Answer 12

but my first option was c and I got It wrong......-.-

Answer 13

@sawq

Answer 14

oh. im gonna try again. i want to help u

Answer 15

thank you @sawq

Answer 16

All you really need to do is plug in c and a and check

Answer 17

c = 20 and a = 6

Answer 18

ok........

Answer 19

the building time is 4c+6a<120
testing time is: 4c+4a <100
when c=10
and a=12
the building time: 112 ≤ 120. Yes
the testing time: 88 ≤ 100
So it's D
I hope I did it right this time... :/

Answer 20

but if I would do that it would be a or c....@jenniferjuice
I AM SOOOO CONFUSED RIGHT NOW...

Answer 21

@sawq isnt c = 20 and a = 6 ?

Answer 22

what? Im getting confused myself right now... @jenniferjuice

Answer 24

reference to old version of question

Answer 25

The question being asked as of now is modified to c = 20 and a = 6

Answer 26

oh so then lets switch it, Why did i do those numbers????

Answer 27

children I thnk was 20 bikes and adults were 6 bikes

Answer 28

so that's why you probably did tht

Answer 29

I'm really not good at inequalities. Sorry.

Answer 30

:( @quickstudent

Answer 31

the building time is 4c+6a<120
testing time is: 4c+4a <100
when c=20
and a=6
the building time: 116 ≤ 120. Yes
the testing time: 104 > 100
So its definitely not c or d.
Is it a or b?
i guess a

Answer 32

ok thank u for trying to help me, if I get it wrong again, I won't blame u ;)

Answer 33

np! i hope you get it? are u doing a or b? cuz u sed you thought it wasnt a. But i think it is.
