false
That statement is FALSE
The true statement is that 25 is a multiple of 5
(13 - 6) x 5 = 56 - 21
It has no solution. Equations have solutions, but expressions have not. Had you asked, 'What is the solution to -2x + 5 + 21 = 0 ?', then I would reply, '26 = 2x; therefore, x = 13', is your solution. You can check this, to see whether it is true. The equation is clearly true, if we substitute 13 for x: -2(13) + 5 + 21 = -26 + 5 + 21 = 0. The moral is that equations are statements and may be true or false. Mere expressions are not statements, and they are therefore neither true or false.

1. false 2. true 3. false 4. true, but that statement can be a compound statement, ie a statement-block between {} 5. false
That statement is FALSE
It is a FALSE statement.It is a FALSE statement.It is a FALSE statement.It is a FALSE statement.
The statement is false.
AND,OR,NOT AND(&&): if both statements are true, result is also true,else false OR():either one statement must be true for result to be true NOT(!):opposite/reverse of i/p Example: int i=5; if(i==5&&i>3) printf("true"); here 5==5 and greater than 3 also;result is true NOT: int i=0; if(!i==1) printf("true"); here NOT(1) is 0 same as NOT(TRUE)=FALSE NOT(0) is 1 same as NOT(FALSE)=TRUE
There is no equation. An equation is true, whereas the statement ( 5 + 7 = -12 ) is false.
True
The true statement is that 25 is a multiple of 5
true
True. Apatite is harder than calcite on the Mohs scale, so it can scratch calcite.
