Answer:
sorry I don't know please forgive because I can't copy the question
So if a number is 5 or greater you round up but if the number is 4 or less you round down so the number 6 is above five so you would round the 6 to 10 therefore making it 7.8 instead of 7.76
It is possible to convert a fraction to a decimal in mathematics. First, -3/11 is a fraction. To convert a fraction which is -3/11, divide 3 by 11 which you get .272727... and you get the idea. The '27' repeats. Therefore, the answer would be -.27 with a <span>Vinculum symbol which is a horizontal line above the number to indicate its repeating. Also, don't forget to put a negative sign!</span>
- (1 + 7x) - 6(- 7 - x) = 36
- 1 - 7x + 42 + 6x = 36
41 - x = 36
- x = - 5
x = 5
