x+15
To find the number that, when added to -15, gives a sum of 0, you can set up the equation: -15 + x = 0. Solving for x gives you x = 15. Therefore, the number you need to add to -15 is 15.
Let the number be represented as ( x ). The expression for the sum of 10 times the number and 15 added to 11 times the same number can be written as ( 10x + (11x + 15) ). Simplifying this gives ( 21x + 15 ). Therefore, the sum is ( 21x + 15 ).
You will have 3(x + 5) or 3x + 15
The sum of 45 and 15 equals 60. 15 x 3 equals 45.
If x + 7 = 15, then 15 - 7 = x, therefore x = 8.If x = 8, then 4x is equal to 4 x 8 = 32.
(x + 15)
It is 15 + 1x.
Let the number be x and if 9+2x = 15 then x equals 3
x+15 if you are trying to find the value of x it would be x+15 x=-15
Well, honey, if the sum of a number and 7 is 15, then all you gotta do is subtract 7 from 15. That'll give you the number, which is 8. Math doesn't have to be harder than picking out a good bottle of wine, darling.
Let the number be represented as ( x ). The expression for the sum of 10 times the number and 15 added to 11 times the same number can be written as ( 10x + (11x + 15) ). Simplifying this gives ( 21x + 15 ). Therefore, the sum is ( 21x + 15 ).
(15 x 1) + (15 x 3) = 15 x 4 = 60
3(z+15)
You will have 3(x + 5) or 3x + 15
The sum of 45 and 15 equals 60. 15 x 3 equals 45.
If x + 7 = 15, then 15 - 7 = x, therefore x = 8.If x = 8, then 4x is equal to 4 x 8 = 32.
