What is 15 less than a number squared?
x² - 15
Six times a number minus five is less than twice the number plus ten?
Six times a number minus five is less than twice the number plus ten. 6 * n - 5 < 2 * n + 10 6n - 5 < 2n + 10 4n - 5 < 10 4n < 15 n < 15/4 This statement will hold true for all n < 15/4
The product of what number and 7 is less than 49?
your expression is this... 7x < 49 x < 7 so any number below 7 can be your answer
What is one third of a number that is 10 less than the number itself?
one third of a number that is 10 less than the number itself = 15Let x = the number1/3 of a number = 1/3 * x10 less than the number itself = x - 10Equation: 1/3 * x = x - 10multiply the equation by 3(1/3 * x = x - 10) 33/3 x = 3x - 30x - 3x = -30-2x = -30-2x/-2 = -30/-2x = 15
If you multiply a non zero whole number by a decimal less than one would the product be less than or greater than the whole number?
It depends on the signs of the two numbers.The answer is tricky when at least one number is negative because you have to remember that "less than" means "farther to the left on the number line" and NOT "greater in magnitude". E.g. -20 is less than -4 because -20 is farther to the left even though its magnitude (absolute value) is greater.There are four possible cases:Whole number and decimal are both positive: The product is less than the whole number. The decimal reduces the magnitude of the product, so the product is to the left of the whole number on the number line. E.g. 0.5 * 10 = 5, which is less than 10.Whole number positive, decimal negative. The product less than the whole number. A negative times a positive is ALWAYS negative, so regardless of its magnitude the product is to the left of the positive whole number on the number line. E.g. 15 * (-0.2) = -3 and -3 < 15Whole number negative, decimal negative. The product is greater than the whole number. The product is negative but like in Case 1, the magnitude of the product is smaller, so the product is to the right of the whole number on the number line. E.g. (-8) * 0.3 = -2.4 and -8 < -2.4Whole number negative, decimal negative. The product is greater than the whole number. A negative times a negative is positive, and ANY positive number is always greater than any negative number regardless of magnitude. E.g. (-0.25) * (-12) = +3 and -12 < +3
Which expression shows 15 less than 7 times a number?
15 less than 7 times a number is:15-7n
I am greater than 15 and less than 40 if you double me i become a number that ends in 0 1 out of5 of me is equal to 5?
25
I am greater than 15 and less than 40 If you double me I become a number that ends in zero One fifth of me is equal to 5 Who Am I?
25
Why is15 a deficient number?
That means that the sum of the number's factors, less than the number itself, is less than the number in question - in this case, if you add the factors of 15 (except 15 itself, which is also a factor of 15), you get a total that is less than 15.
Is an even number less than 15?
No, however there are even numbers less than 15. An even number is any number that can be divided by two evenly, so it can be greater than 15 too.
What is 15 less than a number squared?
