The sum of 3 numbers is 1305. The first number is 360. The second number is twice the first number. What is the third number?

225

Step-by-step explanation:

x + y + z = 1305

x = 360

y = 360×2 = 720

z = 1305 - 360 - 720 = 225

225

Step-by-step explanation:

since the first number is 360 and the second number is twice the first number meaning it's (360×2) which is 720,you have to add the two and subtract by 1305 to find the value of the third number(which I have represented by x)

360+720+x=1305

1080+x=1305

x=1305-1080

=225

therefore the third number is 225,you can prove it by adding the three to see whether you will get 1305.
