The answer is 45 and 81. To find it out you need to use double algebra. 1. (x+y)-(x-y)=90 x-x=0 y+y=2y/2= 1y=y 90/2= 45 y=45 2. (x+y)+(x-y)=162 y-y=0 x+x=2x 2x/2= 1x=x 162/2=81 3. check your work x+y-x-y=90 81+45-81-45=90- x+y+x-y+=162 81+45+81-45=162 81+45= 126 81-45=36 126+36=162 That is how you find the answer.
Let the numbers be x and y. Given that x + y - (x - y) = 90 and x + y + (x - y) = 162. Simplifying these equations gives y = 45 and x = 72, so the numbers are 72 and 45.
Addition of numbers is neither exothermic nor endothermic because it does not involve any chemical reactions or energy transfers between substances. It is a mathematical operation performed to find the sum of two or more numbers.
The distributive property states that when multiplying a number by the sum of two other numbers, the result will be the same as if each of the two numbers were multiplied by the first number separately and then added together. In algebra, it is commonly written as a(b + c) = ab + ac. This property is essential for simplifying expressions and solving equations.
Subtraction is an operation in mathematics that involves finding the difference between two numbers. The result of a subtraction operation is called the difference. Subtraction is the opposite of addition, and it involves taking away one quantity from another.
The atomic number of an element is the sum of the number of protons in the nucleus.
First, you have to know the difference between Prime Numbers and Composite Numbers. Prime Numbers are numbers that has only two factors: 1 and itself. Composite Numbers are numbers that have factors other than 1 and itself. Composite numbers are always even, with only one exception: number 2. Two is the ONLY EVEN PRIME NUMBER. Never will you encounter another even prime number because it will always have AT LEAST 3 factors. # ITSELF. # ONE. # TWO. Now that we know the difference between Prime and Composite, we can answer your question. 4,567,278 is an even number. It is divisible by itself, one, two and probably more numbers. Therefore, it is COMPOSITE!
The numbers are 98 and 64
65 + 97 = 162 97 - 65 = 162 The two numbers are therefore 65 and 97.
The difference of two numbers is 8. Their sum is 22. What are the two numbers?
It is 162.

Two numbers with a sum of 4 and a difference of 9 are -6.5 and 2.5.
Difference. A sum is the result of adding two numbers, and a difference is the result of subtracting two numbers.
