10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x
40 divided by 4= 10 10 x 3=30 so three quarters of 40 is 30

Its "30 dollars". use calculators brother it saves times.
The standard for conversion of metric (cm) to Imperial (inches) is 1 inch = 2.54 cm. Hence 30 cm x 40 cm x 10 cm = 30/2.54 X 40 / 2.54 x 10 /2.54 = 11.811 ins. X 15.748 ins. X 3.937 ins. As an approximation 12 ins. X 16 ins. X 4 ins.
Let x = one number. x + 10 is the other one. 2x + 10 = 40 2x = 30 x = 15 x + 10 = 25 15 + 25 = 40
