since the cross multiples are equal, you find a product and use the inverse operation as you would in an equation
Example 4 is to 36 as 3 is to X: 4/36 = 3/X --> 4*X = 3*36. Divide both sides by 4, to solve for X = 27.
is over of = percent of 100
is/of=%/100
What is 10% of 40.
is = x
x/40 = 10/100
cross mulitply 40*10= 400/100=4 x=4

How do you solve the Fahrenheit if the given is Celsius?
F to C: Deduct 32, then multiply by 5, then divide by 9 C to F: Multiply by 9, then divide by 5, then add 32
2x divided by 7 equals 11 solve for x?
2x/7 = 11 Multiply both sides by 7: 2x = 77 Divide both sides by 2: x = 77/2 = 38.5
To solve 5x 65 you must both sides by 5?
divide
Which best describes how to solve the equation 64x equals 37?
Divide both sides by 64 to find the value of x
Solve the system by the elimination method 7x-9y equals 35 plus -3x plus 6yequals -15?
7x - 9y = 35-3x + 6y = -15 (divide the second equation by 3, after that multiply it by 7)7x - 9y = 35-7x + 14y = -35 (add both equations)5y = 0 (divide both sides by 5)y = 07x - 9y = 35 (substitute 0 for y)7x = 35 (divide both sides by 7)x = 5Thus the solution of the given system of the equations is x = 5 and y = 0.
