The sum of 3 and a number, equaling 5, (if you want to know what the number is...) is 2
3+2=5
That would be an addition problem such as 2+3=5 5 would be the sum.
3(x+5)
(x + 5) + 3
A number ending in 0 or 5, whose digits sum to a multiple of 3.
If the sum of the digits of the number is a multiple of 3 then that number is divisible by 3. For example: 156351 The sum of the digits is 1+5+6+3+5+1 = 21 which is divisble by 3 156351/3 = 52117
It is the sum of the whole number part and the fractional part. eg 5 2/3 = 5 + 2/3
5x + 6
5 is the sum. 2 and 3 are the addends.
5
That would be an addition problem such as 2+3=5 5 would be the sum.
3(x+5)
A number ending in 0 or 5, whose digits sum to a multiple of 3.
That number would be 3
If the sum of the digits of the number is a multiple of 3 then that number is divisible by 3. For example: 156351 The sum of the digits is 1+5+6+3+5+1 = 21 which is divisble by 3 156351/3 = 52117
2(x + 3)= 5? x + 3 = 2½ x = -½
The appropriate equation is: 5*(-3 + N) = -20
You can find the sum of 8, 5, and 7, and then multiple that sum by 3, which is equal to 60.
