Question

The sum of two numbers is 
26. 
The first number is 
3/10 
of the second number. What are the numbers?

Answer 1

Hi welcome to Openstudy!

let x be the first number
and y be the 2nd number

x + y = 26

x = 3/10y since it says "The first number is  3/10  of the second number"

solve for the two unknown numbers by combining the two equations we have:

x+ y = 26
3/10 y + y =26

can you simplify this to solve for y? i'll check it don't worry, just try :)

Answer 2

20?

Answer 3

:-)yep

Answer 4

ahem why did you delete that ?? O.o

Answer 5

yes great :)

so now let's solve for x, using x= 3/10 y
plug in the y value that you calculated in x = 3/10 y
and tell us what you will get

Answer 6

delete what? ? O-o?

Answer 7

*secret*

Answer 8

lol okay :3

Answer 9

@idiotXatXmath what are we going to get if replace y with 20 in x= 3/10 y?

it will look like this: x = 3/10 (20) which is equal to?

Answer 10

my bad 6y

Answer 11

yes! x will be six

therefore the unknown numbers that you are looking for are 20 and 6 ^_^
great job @idiotXatXmath !
