Question

Thom worked 18 hours last week at the sporting goods store and earned $92.00. If he continues to earn the same hourly pay, how many additional hours must he work to earn another $138.00?

Answer 1

can someone please try to help im not good with proportions

Answer 2

Well, if he worked 18 hours, and got payed 92 dollars, how much did he get payed per hour?

Answer 3

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.

Answer 4

ok yea that makes sense so just break it down step by step

Answer 5

Yes.

Answer 6

how do i find a proportion for x like this x/6 = 6/4

Answer 7

but its like x is above the 6 and the 6 is above the 4 i guess like cross multiply

Answer 8

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

Answer 9

wow thank u i should of typed it like that lol ok so 4x = 36 and x = 9 but is that the answer ?

Answer 10

Yes.. you are wanting to know what x equals and x = 9

Answer 11

ok so i should only get one answer which is x

Answer 12

In other words
9 6
- = -
6 4

if you reduce both of those fractions you get

3
-
2

Answer 13

ok can u please tell me how to reduce do u just find the factors that go into each numbers

Answer 14

ok im confused im trying to do 9.5/19 and x/30

Answer 15

please can someone help

Answer 16

i did 9.5 times 30 and got 285 but now im stuck

Answer 17

9.5 x
--- = ---
19 30

30(9.5) = 19x
285 = 19x
x = 15

Answer 18

oh so i do 30 times 9.5 ok sorry i did the oposite

Answer 19

It doesn't matter which way you multiply, you get the same answer.

Answer 20

oh ok yea because i did get 285

Answer 21

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?

Answer 22

shadow / height = shadow / height

Answer 23

9 divided by 6 = 1.5 correct

Answer 24

9 6
- = -
x 4

9(4) = 6x
36 = 6x
6 = x

Answer 25

i had to cross mutiply

Answer 26

WAIT I WAS WRONG.

Answer 27

um ok

Answer 28

9 4
- = -
x 6

9(6) = 4x
54 = 4x
16 = x

Answer 29

Shadow of tree Shadow of person
------------ = --------------
Height of tree Height of person

Answer 30

ok i understand now so that would mean the answer is 16=x

Answer 31

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

Answer 32

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)

Answer 33

its ok really everyone makes masteakes

Answer 34

ok so the answer is 13.5

Answer 35

Yes

Answer 36

:) thank you wonderful

Answer 37

Answer 39

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

Answer 40
