Question

i am stuck on this problem and none of the multiple choice answers fit
the uk, denmark, and norway have a total of 20 territories. norway has 1/5 as many as the uk. denmark has 2 territories. how many territories does norway have.

Answer 1

hey, how's it going

Answer 2

good thanks

Answer 3

uk denmark and norway have 20 territories, denmark has 2 territories so uk+norway = 18

Answer 4

now you need to set up a system of equations to solve

Answer 5

the first one is u+n=18

Answer 6

i got that then i divided it by .2 but it didn't fit

Answer 7

try to turn the sentence-form information they give you into a math equation

Answer 8

divided what by .2? did you understand the idea of a system of equations?

Answer 9

the 18 because it said that had 1/5 as many territories...sorry meant multiplied 18 by .2

Answer 10

basically if you have two variables, you need two equations to work with to solve for the variables

Answer 11

1/5 as many territories as the UK

Answer 12

not 1/5 as many territories as 18

Answer 13

opps

Answer 14

norway has 1/5 as many as the uk.

Answer 15

norway = 1/5 * uk

Answer 16

n = 1/5 * u

Answer 17

sorry we just start algebra and the teacher didn't explain this and i couldnt find an example in the book

Answer 18

don't be sorry, it's no problem

Answer 19

now that you have n+u=18 and n=1/5 * u, you want to substitute n back into the first equation so you have only 1 variable to work with

Answer 20

i'm so confused :(

Answer 21

would it be 1/5 * u+u=18 or 2u=18-1/5 or something like that

Answer 22

are you still able to help me

Answer 23

thanks for your help i will ask the teacher thank you i have to go to bed
