45 - 100 = -55
1,000 if u add 55 and 45 u get 100 and the differance of 55 and 45 is 10 so multiply 100 and 10 to get 1,000

1 + 55 + 345 + 87 + 98 = 586
(-45) - (-55) *Minus plus is equals to minus.( -,+ = - ) minus minus is equal to plus (-,- = + ) and plus plus is equal to plus (+,+ = +) so the ans is that, (-45) +55 -45 + 55 (+10)ans Greater value sign has been used, which is 55 so the ans is +10.
For this set of numbers, 45 87 61 73 55 78 69 80: σ=14.0204
45-5x = 5x+55 -5x-5x = 55-45 -10x = 10 x = -1
45.
4x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9
The answer is 100. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
Assuming that there is a "plus" after the second 58, the answer is - the associative property of addition.
45 -87 = -42
simply do addition and your answer comes out to be 246
