Their sum is three times the middle number.
"The sum of a number and three times another number is 18. find the numbers if their product is a maximum?"
The sum of three times a number and its square is 10 more than 6 times a number?
The number is 7.
Is this exactly how the problem was written?
21 and 63
The larger number is 12.
450N, where "N" represents the unknown number.
The answer is 3
The numbers are 21 and 63.
The mean times three will be the total of all three numbers. Multiply the mean times three and subtract the sum of the two numbers from that total.
Negative two (-2).
( 5 + 3x )
3(x + 12)
30 is the Answer
Sum = Sum + first number Sum = Sum + second number Sum = Sum + third number Average = 1/3 x Sum
