THE WIDTH OF A PHOTOGRAPH IS 4 CENTIMETERS MORE THAN THREE TENTHS OF THE LENGTH. IF THE WIDHT IS 13cm.FIND THE LENGHT
-----------------------------------
Let the length be "x" cm.
Width is (3/10)x+4
------------------------
EQUATION:
(3/10)x+4 = 13
Multiply thru by 10 to get:
3x + 40 = 130
3x = 90
x = 30 cm (The length)
