n+3 the sum of a number and three means a number plus three.
in the equation 3+4=7, 3 and 4 are the addends. 7 is the sum.
It means that some number is having 14 added to it. The sum of 3 and 14, for example is 3 + 14.
If: 9+x = 3 then x = -6
The associative property means that in a sum (for example), (1 + 2) + 3 = 1 + (2 + 3). In other words, you can add on the left first, or on the right first, and get the same result. Similar for multiplication. How you use this in an equation depends on the equation.
3(x + 12)
It is an algebraic equation.
n+3 the sum of a number and three means a number plus three.
in the equation 3+4=7, 3 and 4 are the addends. 7 is the sum.
The appropriate equation is: 5*(-3 + N) = -20
3 (n + 7) = 16
It means that some number is having 14 added to it. The sum of 3 and 14, for example is 3 + 14.
If: 9+x = 3 then x = -6
i dont now
I must change your description to read " ... 3 times as much as ... ".Then the equation is 0.33 N = 3 x (0.17 N) . The equation has no solution. That means that no numbercan make the equation a true statement.
No. The sum of its digits, 5 + 3 + 1, is divisible by 3, which means the number itself is also divisible by 3.
1/2 x + 2/3 x < 14
