The sum of eight and a number ( y ) can be expressed mathematically as ( 8 + y ). This represents the total when you add the constant value of eight to the variable ( y ). The result will depend on the specific value of ( y ).
4 + y.
The word sum is the clue. It means the problem will be an addition problem.y + 3(8) = ?y + 24 = ?
x + y = 48
16 + x = y
5+y=12
4 + y.

16 + x = y
There is no two digit number which, when added to Y gives Y.
x+y=6x^2 + y^2=20 x=2 and y=4 or vice versa
The expression "twice the quotient of 50 and the sum of a number y and 8" can be written mathematically as ( 2 \times \frac{50}{y + 8} ). This represents taking the sum of ( y ) and 8, finding the quotient of 50 divided by that sum, and then multiplying the result by 2.
y=x+70
In an addition sum, if the missing number is the first number, for example, x + 5 = 10, then to find x, perform the sum 10 - 5, producing the solution x = 5. In a subtraction sum, if the missing number is the second number, for example, 7 - y = 4, then to find y, perform the sum 7 - 4 = 3, production the solution y = 3.
To write the sum of a number, you typically express it as an equation or an algebraic expression. For example, if you want to represent the sum of the number ( x ) and another number ( y ), you would write it as ( x + y ). If you're summing multiple numbers, you can extend this to ( x + y + z + ... ). In formal mathematics, the summation symbol ( \Sigma ) can also be used to denote the sum of a series of numbers.
Not necessarily. If the number is 0, then the sum of 8 times the number and -192 is -192.
