Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36
hope this helps!!
Im not sure, but i will try to get back to you
we are ratio as

It will be equivalent to only those terms which would be multiple of this term
so, we will multiply top and bottom term by 5
and we get



so, it is very similar to 12/35
so, it will be equivalent to 12/35
so, option-C.......Answer
I think the answer is 6 because 900/150= 6 and 6X150 is 900 :)
