Well, if he worked 18 hours, and got payed 92 dollars, how much did he get payed per hour?
anonymous
  • anonymous
The question is how much did he make per hour.... per means to divide so word for word make per hour means 92 / 18 That would give you 5.11 per hour. so how many $5.11 are there in $138 138/5.11 27.0058 hours I would assume you would answer 27 hours.

ok yea that makes sense so just break it down step by step
anonymous
  • anonymous
Yes.

how do i find a proportion for x like this x/6 = 6/4
anonymous
  • anonymous
but its like x is above the 6 and the 6 is above the 4 i guess like cross multiply
anonymous
  • anonymous
Whenever you have a fraction = a fraction you can always cross multiply (top left times bottom right = bottom left times top right) x 6 - = - 6 4 so x times 4 = 6 times 6 4x = 36 x = 9
anonymous
  • anonymous
wow thank u i should of typed it like that lol ok so 4x = 36 and x = 9 but is that the answer ?
anonymous
  • anonymous
Yes.. you are wanting to know what x equals and x = 9
anonymous
  • anonymous
ok so i should only get one answer which is x
anonymous
  • anonymous
In other words 9 6 - = - 6 4 if you reduce both of those fractions you get 3 - 2
anonymous
  • anonymous
ok can u please tell me how to reduce do u just find the factors that go into each numbers
anonymous
  • anonymous
ok im confused im trying to do 9.5/19 and x/30
anonymous
  • anonymous
please can someone help
anonymous
  • anonymous
i did 9.5 times 30 and got 285 but now im stuck
anonymous
  • anonymous
9.5 x --- = --- 19 30 30(9.5) = 19x 285 = 19x x = 15
anonymous
  • anonymous
oh so i do 30 times 9.5 ok sorry i did the oposite
anonymous
  • anonymous
It doesn't matter which way you multiply, you get the same answer.
anonymous
  • anonymous
oh ok yea because i did get 285

At a certain time of day, a tree casts a 9-foot shadow at the same time that a person 6 feet tall casts a 4-foot shadow. What is the height of the tree?
anonymous
  • anonymous
shadow / height = shadow / height
anonymous
  • anonymous
9 divided by 6 = 1.5 correct
anonymous
  • anonymous
9 6 - = - x 4 9(4) = 6x 36 = 6x 6 = x
anonymous
  • anonymous
i had to cross mutiply
anonymous
  • anonymous
WAIT I WAS WRONG.
anonymous
  • anonymous
um ok
anonymous
  • anonymous
9 4 - = - x 6 9(6) = 4x 54 = 4x 16 = x
anonymous
  • anonymous
Shadow of tree Shadow of person ------------ = -------------- Height of tree Height of person
anonymous
  • anonymous
ok i understand now so that would mean the answer is 16=x
anonymous
  • anonymous
OR You can do Shadow of tree Height of tree ------------- = ------------ Shadow of person Height of person 9 x - = - 4 6 9(6) = 4x 54 = 4x x = 13.5
anonymous
  • anonymous
I am SO sorry... don't know what is wrong with my math. They both = 13.5 because 54/4 = 13.5 (I don't know WHERE I got 16)
anonymous
  • anonymous
its ok really everyone makes masteakes
anonymous
  • anonymous
ok so the answer is 13.5
anonymous
  • anonymous
Yes
anonymous
  • anonymous
:) thank you wonderful
anonymous
  • anonymous
U R Welcome
anonymous
  • anonymous
im going to try the next one if i get stuck ill get back to to
anonymous
  • anonymous
x/27 = 4/9 i did x times 9 and i got 9x the i did 9x times 9x and got 81 is that correct
anonymous
  • anonymous
blexting
