Divide 72 in a ratio of 3:5
Keith_Richards [23]
The ratio is 3:5.
\frac{x}{y}=\frac{3}{5} \ \ \ |\hbox{cross multiply} \\&#10;5x=3y \ \ \ |\div 5 \\&#10;x=\frac{3}{5}y

You have to divide 72, so the sum of x and y is 72.
x+y=72 \ \ \ |-y \\&#10;x=72-y

Set both expressions equal to each other:
x=x \\&#10;\frac{3}{5}y=72-y \ \ \ |\times 5 \\ &#10;3y=360-5y \ \ \ |+5y \\&#10;8y=360 \ \ \ |\div 8 \\&#10;y=45 \\ \\&#10;x=72-y=72-45=27

72 divided in a ratio of 3:5 is 27:45.

I do not know what x is please help
amm1812

Answer:

I think x is 1/2.

Step-by-step explanation:

Because the triangles are similar, you can set 9x + 1 = x + 5. Subtract x and 1 from both sides to get 8x = 4. divide and you get x = 1/2.

(double check me though.)
