Time period is directly proportional to the square root of the length So as we increase the length four times then period would increase by ./4 times ie 2 times.
6x-2
Let the number be x:- 4x+40 = 100-x => 5x = 60 => x = 12 So the number is 12
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
10x + 5 > 12x - 2 7 > 2x 7/2 > x
When 3 times a number is decreased by 4 the result is 17. what is the number?
2n - 8 < 5n + 10 -3n < 18 n < -6
3x+32=4x-15 3x-4x=-15-32 x=-47
The number is 4
Then the number is 20.5
Then the number is 20
7x - 8 = 3x + 4 4x - 8 = 4 4x = 12 x = 3 Check it. 21 - 8 = 9 + 4 It checks.
The number is 26
three times a number decreased by eleven
