60 = 45 + 15
(15 X 3 = 45) thus 45 is thrice the value of 15.
3
Thrice the same number.
Let the numbers be x and y:- If: x+3y = -4 and 3x+y = 44 Solving the above simultaneous equation by elimination method: x = 17 and y = -7 Check: 17+(-21) = -4 Check: 51+(-7) = 44
Add an observation that is bigger than the mean or remove an observation that is smaller than the mean.
Simple! The number is 0.
3
Thrice the same number.
answer is 3 because 27, 54, 81
Let the numbers be x and y:- If: x+3y = -4 and 3x+y = 44 Solving the above simultaneous equation by elimination method: x = 17 and y = -7 Check: 17+(-21) = -4 Check: 51+(-7) = 44
Add an observation that is bigger than the mean or remove an observation that is smaller than the mean.
Thrice is three, "a number" can be shown as n. This is 3n. 3n/3=n
50 x 3 = 150Note: thrice is three.

Oh, what a happy little question! To translate "five less than thrice a number" into an algebraic expression, we can let the number be represented by 'x'. "Thrice a number" is 3x, and "five less than" would be -5. So, the expression would be 3x - 5. Just remember, algebra is like painting a beautiful picture with numbers!
Let the number be 'n' 'Thrice' means three times. algebraically it is written as '3n' 'and '8' is 3n + 8 The answer is '3n + 8' .
Simple! The number is 0.
Let the numbers be x and y:- If: x+3y = -4 and 3x+y = 44 Then: 3x+9y = -12 and 3x+y = 44 Subtracting 3x+9y = -12 from 3x+y = 44: -8y = 56 => y = -7 By substitution: x = 17 and y = -7 Check: 17+3(-7) = -4 Check: 3(17) -7 = 44 Therefore the two numbers are: 17 and -7
