Question

I dont understand can you help me

Answer 1

`(9)/(10)x = 18`

`(2)/(3)y = 18`

we can make these two equations.

solve for x and y:

`(9)/(10) x / (9)/(10) = 18 / (9)/(10)`

x = 20

`(2)/(3) y + / (2)/(3) = 18 / 2 (2)/(3)`

y = 27

The total number can be calculated by:

x + y = 20 + 27 = 47

Your answer:

47

which is D.
