when u add a positive to a negative u see which there is more of. in this case there are more negatives so u know your answer will me negative. when u add a positive to a negative you do:
-9.25+3.72 which you can also just do as 9.25-3.72 but remember to add in your negative sign in since we know your answer must be negative. there for you get
9.25-3.72=5.53 then add your negative sign. your answer is -5.53
There are two expressions in the question but no equation - so nothing to solve.
2m + 717 is an expression. It has no equality (or inequality) sign and so there is nothing to solve.
372 is an integer and so is already rounded to a tenth.
x plus 0.068 is not an equation -- it has no equal sign -- so it can't be solved.
well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9
There is no equation (nor inequality) in the question. There is also no unknown variable. So there is nothing to solve.
(y + 7).(y + 7) = zeroy + 7 = zeroand so y = -7
To solve the above inequality equation it has to have an equality sign so that i group all the the knowns and the unknowns.
372 is composite, as it ends in an even number (0 2 4 6 8), so it is not a prime number,
You should memorize your addition, subtraction and multiplication and division facts so that you just remember that 5 plus 9 is 14.
-5(3n plus 4) 40 is a set of disjointed expressions: it is not a formula and so cannot be solved.
If you mean: 80 = 3y+2y+4+1 then 80 =5y+5 and so y = 15
