Which number replaces the box to make this a true number sentence? 6 × (7 - 3) = (6 × 7) - ( × 3)
The missing number is 49. This is why: 1 plus 2 equals 3, then 3 squared is 9. 2 plus 3 equals 5, then 5 squared is 25. Therefore, the missing number must be 49 to make the number sentence (3 plus 4 equals 7, then 7 squared is 49) true.
The answer is the number that 'x' must be in order to make it true.3 = 12 + xSubtract 12 from each side of the equation:-9 = x
(9+3) - (2 +4) = 6
22 + 3 = 7 Since 2 is the only even prime number, this is the only number for which this holds true.
Is |-8|+|3|=|-8+3| true or false?
5 plus 3 plus 7 does equal 5 plus 7 plus 3; this is an example of the commutative property of addition. Therefore, the statement is true.
The trivial answer is: Because there is no possible number that 'x' can beand make the equation a true statement.If the equation is true ... if the left side is actually equal to the right side ...then it must still be true after we subtract the same thing from both sides.Let us subtract 4x from both sides. Then we have 3 = 1 .That statement is clearly not true. So there's no way for the original equationto be true, regardless of what number you tell 'x' to be.
3 is a number and plus 3 is adding three to a number
true. 5+3=8 8+7=15 5+7=12 12+3=15
3 is the true!
