n - 4 = -15
Multiple of 4 less than 15
First write the equation for this which is (n / 4 ) - 5 = 15. The number is 80. 80 divided by 4 equals 20 and 20 minus 5 equals 15.
989. If there is a remainder of 2 when divided by 3, the number is one less than a multiple of 3. If there is a remainder of 4 when divided by 5, the number is one less than a multiple of 5. Thus the number required is one less than a multiple of the lowest common multiple of 3 and 5 (that is 15). So what is needed is an even multiple of 15 less than or equal to 1000: 1000 ÷ 15 = 662/3 Thus the highest even multiple of 15 not greater than 1000 is 66 x 15 = 990, and the required number is 989.
13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
The number is less than 18.
Multiple of 4 less than 15
4p - 9 > 15
3/15 is less than 4/7.
X = number. 4X + 9 = 2X - 15 ===========
First write the equation for this which is (n / 4 ) - 5 = 15. The number is 80. 80 divided by 4 equals 20 and 20 minus 5 equals 15.
Because half of any number's factors are less than its square root. Once you have half, you can find the other half. The square root of 15 is less than 4.
12 is the only number which satisfies this. Multiples of 4 are: 4, 8, 12, 16, . . . .

4 more than 15 is 4 + 15 = 19.
4x - 11 = 49 4x = 60 x = 15
It is 15 when rounded to the nearest whole number because .4 is less than .5
