Answer 9

it's rather self explanatory

Answer 10

Ugh, I hate these.

Answer 11

thst isn't really helpful. It just holds you back to say that. Anyways find "One number is 7 times as large as another" or something similar on that page I linked to, then tell me what it is

Answer 12

the first 1 i guess.
x+7?

Answer 13

"ten more than x" uses none of the same words as "7 times as large"

Answer 14

look

Answer 15

It doesn't sound like you actually even read the site at the current moment in time

Answer 16

none of them say large though...that's throwing me off

Answer 17

did you scroll down to where it tells you what words mean what functions?

Answer 18

Yup

Answer 19

what does times mean?

Answer 20

Answer 21

so, if something is 7 times larger than a number,

Answer 22

let "a number"= x

Answer 23

@Rohith15 , why u delete it?

Answer 24

it was wrong
i took 7 greater than the first number

Answer 25

i dont think the sum is 72/7

Answer 26

well, I just need a formula to work with. I can probably go off of that

Answer 27

see you take the two numbers as x and 7x. Now take their individual reciprocals i.e, 1/x and 1/7x. Their sum is given. Equate both sides . Take LCM. You will get an equation. Solve it.

Answer 28

1/x+1/7x=72/7?

Answer 29

yep. you got it!!

Answer 30

So, I just added the numerator & denominator...I just got lost again.

Answer 31

See when i simplified i got x = 1/9 an the other number is 9. But they are not satisfying, So I thought the sum must be wrong

Answer 32

The 1/9 s correct, but not the 9. I jut checked the answer

Answer 33

@wolf1728 , can you help me, please?

Answer 34

i got it!!!

the answers are 1/9 and 7/9. Just take the reciprocals nd add nd u get 72/7

Answer 35

Thank you !!!!
