To solve this equation, you can represent "4 less than a number n" as n - 4. So, the equation becomes n - 4 = -15. To isolate n, you can add 4 to both sides of the equation, resulting in n = -15 + 4, which simplifies to n = -11. Therefore, the number n is -11.
The multiple of 4 less than 15 is 12. A multiple is the result of multiplying a number by an integer. In this case, 4 multiplied by 3 equals 12, which is less than 15. Therefore, the multiple of 4 less than 15 is 12.
Let's denote the number as x. The quotient of the number and 4 is x/4. Five less than this quotient would be (x/4) - 5. The equation we have is (x/4) - 5 = 15. By solving this equation, we find that x = 80.
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.
