What number gives the same result when it is added to five as when it is multiplied by five?
1.253x1.25 =6.253+1.25=6.25 this is the correct answer i checked it
Why does negative two plus positive two equal zero?
Because if a negative is multiplied by another negative it will always be positive. But, if a positive is multiplied or divided by a negative it will always be negative. If the two signs are the same and or being multiplied or divided they will be positive. If the two signs are different and or being multiplied or divided will be negative. True, but the question is not about multiplication, but addition. i like to think of it like this on a number line there are positives and negatives -3 -2 -1 0 1 2 3 if you added 2 to zero you move up to the number positive 2 then move down two number, which represents subtracting two or negative two. you should end up on zero
What is A number sentence that gives two expressions that have the same value is a?
equation
A number multiplied by itself and then by itself again gives - 1000. What is the number?
Let's label the number we seek as x. Then: x * x * x = 1000, which is the same as: x3 = 1000, let's cubic root both sides: [that is equivalent to raising both sides to the power of 1/3: (x3)1/3 = 10001/3 ] x = 10, which is our result.
Does the inequality sign change when both sides are multiplied or divided in an equation?
no because if the same is added to both sides they stay inequal example: 4≠6 (*5) 20≠30
