Let the number be x: 7x < or = to 6x-2 7x-6x < or = to -2 x = -2
20 less than 2 times a number is 40 = 2x - 20 = 40Let x = the number2 times a number = 2x20 less than = - 20is 40: =40Translating it into mathematical symbols :2x - 20 = 40
2x = 3x - 22x - 3x = -2-x = -2x = 2Therefore, the number is 2.
Thirty decreased by three times a number is six less than three times the number. Find the number.
2/3 the number. Two thirds the number
Let the number be x: 7x < or = to 6x-2 7x-6x < or = to -2 x = -2
2 times 3 = 6 which is less than 7 or 1 times 3 = 3 which is less than 7
Let the number be x 4x - 2 < 3x 4x - 3x < 2 x < 2 (x must be less than 2 for that to be possible)
5x - 2
2x = 3x - 22x - 3x = -2-x = -2x = 2Therefore, the number is 2.
2/3 the number. Two thirds the number
5A-2
3x + (x-2) ----> 3x + x - 2 = 4x - 2, so the answer is four times the number, minus 2.
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
three less than four = 1 1< *number* > 4 times the sum of the number + 1 1 < *number* > 5 So all numbers that are greater than one but less than five. 2, 3, 4
the number is 8 2 times 8 = 16 16 minus 5 = 11
Suppose the number is x. The sum of the number and two is x+2 Four times the sum is 4(x+2) The number times 8 is 8x 24 less than the number times 8 is 8x-24 4(x+2) = 8x-24 4x+8=8x-24 so 4x = 32 and x = 8
