What is the equation to the problem the sum of one half of a number and 6 equals one third of the number?
1/2x+6=1/3x 3x+36=2x 3x=2x-36 x=-36
What size is 2x?
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
Why is x plus x equal to 2x?
It is equal to 2x because if you were to replace the "x" with a number say, 2 for example so 2 + 2 would be 4 and 2 times 2 would also be 4 which is what "2x" stands for (2 times x). So then if you had x + x you would get 2x.
What is nine more than four times a number is the same as one less than twice the number?
9+4x=2x-1 2x=-10 x=-5
Replace 7 for x and evaluate the expression 9x - 2x?
X = 7 9x - 2x = 49

One number is 10 more than the other find the number if their sum is 40?
Let x = one number. x + 10 is the other one. 2x + 10 = 40 2x = 30 x = 15 x + 10 = 25 15 + 25 = 40
Nine less than twice a number is thirty one what's the number?
The Answer:You are implying that 2x - 9 = 31. Add 9:2x = 40Divide by 2:x = 20Therefore, the number must be 20.
What is this in number form Seven less than twice a number is negative one hundred forty-seven?
Let 'x' represent "the number": 2x - 7 = -147 Solving: 2x = -140 x = -70
How do you perform 2x plus 2y and raise the whole thing to the negative one?
The answer to your question is (2x + 2y)^-1 = 1/(2x + 2y)^1. When you raise a number to a negative power, you can rewrite it by dividing one by the original number with the negative sign dropped from the exponent. Because the power here is 1, you can rewrite the answer again to 1/(2x + 2y) since any number raised to the power of 1 is simply the number itself. You can't add 2x and 2y because they are two different variables.
If 12 is decreased by twice a number is -7 what is the number?
Let the number be x 12-2x = -7 -2x = -7-12 -2x = -19 x = 9.5
