2(8 + 5) = 2(13) = 26
The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
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.
Let the number be represented by ( x ). According to the problem, if the sum of the number and five is tripled, it can be expressed as ( 3(x + 5) ). This is equal to eight less than twice the number, or ( 2x - 8 ). Setting up the equation, we have ( 3(x + 5) = 2x - 8 ). Solving this gives ( x = -1 ).

According to the statement twice a number minus 2 is 8 the answer is 5.
The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
2n + 8 = 33
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
five times the sum of a number and 8 is -15.
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
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.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
