Since they must total 30, and be equal, divide 30 in half. 30 divided by 2 will give you the answer.
If the numbers in the specified range are specified from lower to higher, then, to be in the range, your number must be greater than or equal to the first, and it must also be less than or equal to the second.
"Mean" means average. To get this, you must add the numbers and divide them by how many numbers there are. For instance, What is the mean of 29, 30, 67, and 52? Add them up to equal 178, then divide it by 4, which is 44.5.
The answer depends on what mathematical operations are permitted and on whether or not all four number must be used.

The sum of the mass numbers and the sum of the atomic numbers must be equal on both sides of a balanced nuclear equation.
The oxidation numbers in a neutral compound must equal zero. This is because the overall charge of a neutral compound is zero, so the sum of the oxidation numbers must balance out to zero.
5 odd numbers must always equal an odd number so can never equal 1000
If ' A ' is a number, then that's one of them.The other number must be the same as the first number, becausetwo different numbers can't both be equal to the same number.So both of the two numbers that equal ' A ' must be the same number that ' A ' is.
What are equal sets?? A set is a grouping of numbers. Set P = {1,4,9} if set Q is equal it must contain exactly the same numbers.
equal numbers of positive and negative charges.
Equal parts.
The sum of oxidation numbers in a neutral compound is always zero. In an ion, the sum is equal to the charge of the ion.
An atom must have the same number of electrons and protons to have a neutral charge.
No, because the numerator (top number) must always be larger then the denomenator (bottom number) to be an improper fraction. To equal 1, both numbers must be the same.
There are 9 numbers. Assuming the question refers to a 3x3 "magic" square, the answer is no. The sum of all nine numbers is 36 so each of the 3 rows must sum to 12.
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
